One of the things I'm personally doing is creating water harvesting earthworks in Greece! We are about two weeks away from planting out our food forest. When the swales are full, we can slow, spread and sink 50,000 liters / 13208 gallons of water, recharging the aquifer after giving a good drink to our fruit trees. I am also planting a whole bunch of support species such as acacias, vetiver and willow in order to create biomass that will further absorb carbon.
I'm very curious as to what these water harvesting earthworks are! I'd love to hear more about this. I'll do some research myself but thank you for the guidance!
@@JBaxter-pi8oj Most water harvesting strategies are to control and reduce the surface flow by topology and permeable materials. The idea is to let the water soak into the ground to rejoin the shallow underground acquifers rather than erode the surface and flow away. Swales are basically channels of rocks and pebbles into which the water would flow and it's speed reduced as well as directed into low lying areas where it should soak in, think of them as a French drain or ditch. In India, there's an ancient practice of piling up the soil in chevrons against the natural flow of the water on the surface so they slow down and have a chance of soaking in. If we used permeable pavements on our streets, sidewalk and driveways, a lot more water would soak into the ground to replenish the aquifers. Of course, these are just the shallow aquifers and hence more likely to absorb pollutants. Permeable surfaces are certainly important but offers little mitigation against the probable climate changes from a cessation or slowdown of the AMOC and an AMOC slowdown would likely result in more snow and frozen soil moisture accumulation in the northern hemisphere as less heat is brought north hence the benefits of shallow aquifers accumulation might actually become a moot point. Shallow acquifers aren't really sufficient to buffer the changes in precipitation and snowmelt, it's just something we could do something about. By all means, we should try to harvest water wherever we can but really it has little benefit with AMOC concerns.
Here in Ireland we are at the same latitude as Japan, Victoria Island, Newfoundland etc... and we are far warmer/milder in Winter. Without the AMOC we are fcuked and freezing!
I dunno, I think Japan and Victoria island are probably warmer and milder than Ireland, they grow citrus fruits in BC, and grapes, they barely even experience winter compared to say New York. Due to the wonders of climate patterns, New York seems to get the sh** kicked out of it compared to where I live on the east coast of Canada, despite being a solid 12 hour drive north by car away...
VICTORIA Island is way way way up in the north. Vancouver Island is on Canada's West Coast - City of Victoria is on Vancouver Island. SOURCE - I live in Victoria the city, and I looked on Google maps
I'm an oceanographer. My research was done in the arctic ocean studying sea ice and heat budgets. The concern about AMOC slowing is what it means for the southern ocean. The conveyor belt (as it is colloquially known as) is more than a heat distribution mechanism for the planet. It also distributes nutrients. As AMOC sinks, the North Atlantic Deep Water (NADW) forms. This flows southward and eventually starts to upwell in a region called the Antarctic divergence. This upwelling brings in nutrients that in essence fuels the southern ocean's food web. This is why it is so productive and you have all the krill, baleen whales, orcas, etc, etc. A slowdown in AMOC will result in a slowdown of nutrients upwelling adversely impacting this ecosystem. HOWEVER, recent research have revealed what the potential mechanisms for a complete collapse of AMOC would look like. It is not just the melting of Greenland's ice. This melting does indeed slow down deep water formation. But to completely stop deep water formation, a sudden large volume injection of freshwater needs to happen and happen quickly. Melting of Greenland's ice does not achieve this. As the ice melts, there is mixing, the fresh water gets entrained, but regional currents move this water westward (causing sea level rise along the eastern seaboard of North America). What these new researches found was when a huge amount of ICE breaks off from Greenland, then carried south by currents where they then melt at once, it is this shock to the system that can stop deep water formation. As Greenland's ice melts, the likelihood of huge chunks of ice breaking off continues to decrease. Therefore, this mechanism is unlikely to occur. To determine and measure this mechanism, the researchers used isotopes of Thorium to make these assessments. A second mechanism is a sudden flush of freshwater into the North Atlantic. About 13k years ago, there was a lake in North America called Lake Agassiz. It formed due to the ice sheets melting back. Then around 12k years ago or so, there was a sudden influx of this freshwater into the North Atlantic and it is thought to have contributed to the Younger Dryas era where ocean circulation was disrupted and planet wide temperatures cooled considerably. (This is the 12k years ago period referenced in this video). There is a possibility for a similar situation happening today. In the arctic ocean, there is the Beaufort Gyre. It is an anticyclonic (clockwise) gyre which means there is a concentration of water in the middle (with subsequent downwelling). Due to increased riverine inputs, increased precipitation, loss of sea ice, there is a buildup of freshwater in this gyre. A new oscillatory system, the Arctic Dipole (of which I was a part of in discovering and describing this system) controls whether or not sea ice continues to flow within the arctic ocean or is pushed out through the Fram strait. Right now, this freshwater buildup is contained. If conditions change and become just right, this freshwater in the arctic ocean can be rapidly introduced into the North Atlantic. This would be the necessary shock to stop deep water formation. This is what people need to be keeping close tabs on. I do have my own channel here where I discuss many of such topics and have posted recent videos of this over the past several months.
So I should infer that a collapse could be beneficial as it may trigger a global rapid cooling of the poles while a heating of equatorial regions. Though in the short to medium term this could dramatically disrupt food cultivation as it will eliminate monsoons until the system basically self resets after the rapid cooling period. The issue is with our current rate of additional heating, does this offset the collapse? Can offsetting the collapse and reset actually present more of an issue towards long term survival than that short period of rapid cooling and disruption to food cultivation resulting in the same collapse but at a point where the rapid cooling doesn't take effect due to the excess heating. (Facts to be observed, if AMOC collapses, poles will rapidly cool during their winter periods due to the massively reduced sunlight; the counter will happen at equatorial region as it will begin to rapidly warm and not be regulated with precipitation taking places that are naturally well suited for farming to become deserts (given enough time))
Think they should just start teaching us how some of us might survive after these tipping points because I do not believe our world governments will "allow" the massive changes that are needed to prevent them.
It is unbelievable to me how you can make such a quality video, well researched, animations, interviews etc. etc. Mention AMOC about 150 times, without ONCE saying what it stands for. This was the most frustrating watch ever. For all normal people that watch it and surely don't want to hear constantly AMOC AMOC AMOC without context: It stands for: Atlantic meridional overturning circulation. You're welcome.
you're^ nobody is going to listen to you if you sound uneducated. let me tell you so you can hear. men can't get pregnant. if you voted for kamala you don't understand science, nor are you for it. men can't get pregnant and american democrats have abandoned science.
Here... she keeps leaving this out: "The Atlantic Meridional Overturning Circulation (AMOC) is a system of ocean currents that circulate water in the Atlantic Ocean, carrying warm water north and cold water south." *it makes farming and food production possible on the North American continent and Eurasia.
Thank you, I haven't heard that acronym before, knew about the current and it's affects and possible changes global warming was having, but couldn't figure that out
Also it makes farming and food production possible in South Asia, South America and Africa by stabilising the monsoon rains. I don't think people understand how much we would be fucked by not having those currents
Back in 2015/2016, I was part of an Internnational Arctic Circle Traverse team. We setup the largest Firn Compaction network in history - 13 sites across the entire Greenland icesheet. We were trying to help NASA determine why we were experiencing a significantly accelorated melt beyond what the current models had predicted. We setup data stations, did firn compaction readings, setup Thermister strings 65 feet into the ice sheet, multiple ice core samples at each site, did vacuum measurements, setup radar to track the ice melting through the ice layers, chemical anaylsis of each core back 30 years (10 cm chunks), checked surface reflectivity, and monitored each site's movement using hyper-sensitive GPS tracking. We confirmed there were giant shelves of monophorus ice that were stopping the snow from being absorbed into the sheet and forcing the new melt water to exit off the the icesheet on the surface instead of it's normal absorbtion cycle. We did the same chemical measurements on our ice cores (going back 30 years).
@@OkieJammer2736 This is a long-winded answer because the effects are complex and ripple across the globe in multiple ways. Firstly, the arctic ice sheet won't be able to repair the ice lenses that have formed for decades to come. That damage has already been done, to be frank. Time and carbon polution-reduced atmosphere is the only healer. Locally, the ice sheet is "super lubricated" underneath causing faster movement combined with significant 7x normal run-off. The core damage is already done. We are already seeing some of the effects in increased and stronger weather events due to increased and more frequent carbon overloadiing of our oceans and in turn, clouds absorbing more warm air over the oceans. The most critical effect of the ocean's warming is the effect and ripple effect of it's effect on plankton, the ripple effect on the ocean's food source for much of what the ocean's creatures eat and also it's affet on land animals. Ocean's water levels in the southern hemisphere will increase due to the moon's gravitational force on our ocean. We expect the shifting jet streams to cause instability in weather causing incereased and exagerated droughts. The human effect - Currently, we have a problem of human ego (We can't possibly be affecting the entire planet. This is a normal cycle that can't be stopped.), Greed (Oil and Gas and iit's industries spreading misinformation to distract from it's affect. It's the cows, volcano's, etc that are the poluton. Not us. Don't look here). Ignorance (It's not warmer here. It's colder. The ocean looks the same to me.). What we choose to do as a species will either allow us to recover from what we have already done, or feel earth's inadvertant wrath, to be blunt. The two major absorbtions of carbon polution are trees and the ocean. It's not enough to simply use more effecient forms of energy that are available. How quickly we respond to this crisis will exponentially affect the future generations of everything, either positively or negatively. The ice lenses will eventually be buried deep enough into the Arctic icesheets and lose their effect on the water loss. However, that process can't even start to happen until we reach a balance point of the oceans' and trees' ability to absorb the excess carbon.
I'm reminded of people who downplay the problem of climate change by saying "The climate has changed in the past!" Yeah. We know. That's how we know what it'll do, how we know how awful it is for us, for it to change now, as fast as it is changing. How those shift events in the past, even as slow as they were, devastated ecosystems and caused mass extinctions. How going as fast as it is now will be so much worse, giving life so very little time to adapt, to say nothing of our civilizations and how dependent we are on the climate staying the same with where we live and how we grow our food. This isn't a difficult concept!
Its the speed of change that is deadly. Fastest rate of change in at least 380,000,000 years! Seems like a lot of people are going to ignore it till that becomes impossible. Then blame it on weather weapons and polority switch.
@@guitarista666 We're on track to experience changes over 200-300 years that natural climate events in the record took tens of thousands of years to go through, as measured by ecosystem shifts, global temperatures, and co2 levels.
As a scientist studying AMOC (and in agreement with those scientists who did not want to be interviewed - I’m pretty sure I know who they are), I found this report to be highly biased. Yes, some climate models indicate a 50% slowdown, but just as many indicate no significant change. And higher-resolution models which get the physics of the Southern Ocean and eddies correct don’t suggest much of a slowdown. And AMOC is controlled as much by physical wind-driven upwelling in the Southern Ocean and tropics that is not modeled well in many low-resolution climate models. Also, the idea of a “collapse” comes from model runs in the 1980s that were significantly biased because the salinity and temperature of the North Atlantic was not close to correct. I suspect many people referencing the paper as proof of a “collapse” have never actually read it. Look it up yourself and decide for yourself. Manabe and Stouffer (1988) Two Stable Equilibria of a Coupled Ocean-Atmosphere Model. Journal of Climate, Vol 1, pp 841-866.
But isn't the whole point that the patterns emerging in the temperature anomalies of the North Atlantic are reminiscent of the cooling patch that an AMOC slow-down would produce. This is *despite* the (modern) model predictions suggesting that no major AMOC slowdown should be happening at our current warming. We both know that models are not perfect and unrecognized model biases could mean that we've underestimated the sensitivity of the AMOC to perturbation. If this is true (and I agree - it's early days in trying to determine from short noisy observational datasets if this is indeed what is happening), then a major slowdown of the AMOC could have big consequences over the coming decades.
I'm of an opinion (not asked for assuredly) that a great chastisement is about to be poured out upon mankind. This is but 1 facet of the catastrophe cycle. The sun, the earth's weakening magnetic field, the approaching WWIII, diabolic influence in global society, etc; are examples of equally important other facets influencing our future. Morality is the hidden sign, as it decreases danger increases. This is human history and no one notices.
I'm curious about your thoughts concerning potential effects from the Beaufort Gyre. If the Gyre collapses, it could dump a large amount of fresh water into the North Atlantic.
Funnily enough, they actually showed that terrible “day after tomorrow” movie about the AMOC break down in my middle school science class. It’s a shame that they chose to make a ridiculous disaster movie where the ice literally chases the protagonists down 5th avenue on a real theory
Just a movie. Reality is so much harder to grasp, and propaganda worldwide disabled us to get to a society with decisions based on facts.... Not that I know these facts. I am just sure the more somebody says that he does, the less I trust that person
An article in Scientific American magazine (1970's?) explored the science behind the 'radiosonde' buoys used to map ocean currents. This mapping program was to determine transitions in temperature, salinity and other factors. The authors stated that such transitions were natural 'hiding places' for submarines....sound waves bounce or are refracted by said transitions. Regular mapping of the currents was necessary, as they changed over the seasons. Almost as a footnote, the author noted a weakening in the 'transporter current' that kept central Europe from freezing. 'They' saw the trends over 50 years ago, hid it under Defense.
don't forget that the party that told you this also claims men can get pregnant. i really wish the average human was more intelligent than this... you are so easily manipulated, even back in the 1970's. wow. 🤣🤣🤣🤣
this happens no matter what its how the earth cools it self down. technically we are still in a ice age. watch the beauford gyre once it is let loose its on
I thought that AMOC stood for the Atlantic Mid-Ocean Current. I was incorrect. It actually stands for the Atlantic Meridional Overturning Circulation .
Good video, Really don't like the chart at 12:09 . It is 2025 and we are still increasing our CO2 emissions year on year, yet that chart shows a dramatic slowdown, starting at 2020. Lets be real, we are never going to drop emissions and definitely not within the next 4 years. That chart needs to start at 2030 to be at all realistic.
Dont worry about the chart bcuz we wont ever reach net zero. Billionaires own the world and they dont give a shit about anything or anyone but being the first a hole to be a Trillionaires.
In addition the only reason we had a dramatic slowdown was because of COVID and businesses converting to work from home wherever they could. The dramatic reduction in traffic was why we had dramatic reduction in pollution.
Humans won’t generally accept the facts because it would mean them being much more frugal - no flying, no SUVs, nothing luxury, no global goods, although it would be better for everyone.
@@StefanoCap13 I can't be sure if you're being serious or joking, but an interesting fact is that the fossil records don't show a mass extinction event or a large shift in the climate when the magnetic field last switched. And it's weakening because it's on its way to flipping, so magnetic north would be where today's magnetic south is. As it's one of the things we humans haven't obviously messed up on this planet I'm fine with it being a novelty so far.
Reducing emissions is only part of the solution. I'd like to see a show on reforestation of land and sea. By planting and nurturing kelp beds, sea grasses, and mangrove estuaries, we can remove carbon at the same time. A similar thing happens on land. But we know that it takes about 25 years for a newly planted forest to sequester more carbon than it emits. So we concentrate on prairie grasses, regenerative agricultural practices, and selective logging and replanting.
There’s a channel here on RUclips that does demonstrations of Rewilding Projects across the globe. They are 100% crowdfunded too, do check them you Theyre called Mossy Earth
What are you trying to solve? It's not clear to me that there is an actual problem with the climate at the moment. We were probably closer to the truth in the 70s when we feared the next ice age. Don't get me wrong, humans got some problems with environmentalism, like monocropping, glyphosphate, land use, etc etc ... CO2 is not likely a problem. Tippinging points likely cause a correction back to the normal state of the earth, which seriously more icy cold than anything. Besides, look at CO2 atmosphere concentrations. Everytime they get high.... An ice age comes and they drop. It's almost as if the CO2 concentration _causes_ the ice age to occur.
@@kayakMike1000 It's interesting that you think CO2 isn't a problem. That sounds like the misinformation/ disinformation the oil/ gas industry is putting out. There is very clear evidence that CO2 is a problem. However, you are correct in that it isn't the only problem. From my understanding of this the programme is interested in is finding out (a) if there is a collapse imminent and (b) what the outcomes of that collapse could be. So it is limited to that particular issue.
Reforestation is an excellent idea as it allows nature to take the lead in healing itself. I believe the Japanese experienced the results of deforesting an island that was previously rich in organic matter and the effects of deforestation were that the land could no longer produce "food". Interestingly, it also impacted the ocean in the vicinity. And that included marine life. I recommend the work of Dr. Suzanne Simard, Julia Beresford-Kroeger and Peter Wohlleben for further information.
But can we keep up with the rate of emissions? I mean, if I'm not wrong, the Amazon forest removes from the atmosphere about 2 gigatons of CO2 each year, but we emit like 38, which are 19 amazonias each year. I know that I'm not accounting for biomass etc but my point is that the amount of CO2 we are emitting is no joke. Your approach feels "too slow" proportionally speaking. And if we account for biomass, according to chatgpt the amazon stores like 900 gigatons of CO2 at most, which equals to 25 of emissions at the current year. In other words, we would need to create four full replicas of the amazonia each century to keep up with the rate of emissions.
11:00 - So... what were the consequences of the last AMOC collapse during the last interglacial??? The video explained what the blob indicates but didn't take a further step to explain the consequences of an AMOC collapse during an interglacial period beyond "it's a tipping point and stuff will happen". Will the AMOC collapse still have a cooling effect similar to previous glacial periods or will the effect be different now, given we are in an interglacial period?
Thank you for this series. I am closely watching weather developments because I don’t want to be caught off guard by ‘unprecedented’ patterns and events. I’m trying to harden my home against the extreme events that might occur in my area during my lifetime (which is unlikely to last beyond 2060). I concentrate on this because it’s the only tangible thing I can influence. I don’t expect emissions to decrease until the number of emitters decrease, both consumers and producers. How that’s going to play out is still an unknown - probably a combination of the chaos caused by extreme weather direct damage and climate refugee indirect impacts. There is no evidence to date that individuals and countries are willing to voluntarily reduce their levels of consumption (aka ‘standard of living’) - and considerable evidence to the contrary. Most disappointingly, it appears that democracies are particularly hostile to needed changes.
i mean the changes you just labeled as needed is the control of who can and when they can propagate. no human ever will purposefully decrease the standard of living they have. so ther fore like you say the only thing that can fix it is the reduction of consumers and producers ie killing off humans or controlling the replacement of those humans when they do pass away. at the end of the day thats a dystopian society no one wants. well i shouldnt say no one as there are many people out there who wish to control society. i do have one question tho if you have a dot graph how much data do you need to come up with a conclusion? cause the dot graph we have for our weather history has just started and seeing people jump to conclusions about patterns that cant even be seen as the amount of data we have is not near enough is insane to me.
Democracies are particularly hostile to needed changes compared to what? The authoritarian nations around the world are not in a hurry to lower consumption, emissions and increase recycling for the common good either.
@@PadeMoro yep cause those other countries can give a fuck about how the west views the future of the planet they live in the now they dont have the luxury of worrying about the future THEY WORRYING ABOUT TODAY. must be easy for these lefties to tell people who barely make it day to day to live a worse life so they can feel good about themselves.
I never would've thought that the AMOC was critical for monsoon seasons in China and India. I thought the AMOC was just a North Atlantic climate thing only.
Water has an incredible ability to absorb and transport heat. The AMOC carries gargantuan amounts of heat from the tropics to near the polar regions. Now, warm surface temperatures cause air to warm and expand (becoming low pressure regions). Cold surface temperatures cause air to cool and contract (becoming high pressure regions). Air tries to flow from high pressure regions to low pressure regions, which results in our winds and weather. When you change the AMOC, what you do is cause a major change the pattern of surface temperatures. Changing this pattern of temperatures changes the location and direction of winds, and therefore changes the location and strength of things like rainfall regions. These effects can occur far away (literally on the other side of the planet) from the north Atlantic.
The oceans have impacts around the world, little if anything is isolated. That's why you hear about El Nino and La Nina near the equator having precipitation and temperature impacts thousands of miles away since it can change the air circulation patterns.
I appreciate that you are centering the health of the planet. Your visualizations are impactful. It helps us see how the planet is alive- breathing and circulating nutrients through its oceans and air over land. These circulations are vital for its health. It is our responsibility as human beings to take care of our planet and manage its healthy function-like we ought to do for our own body. I wish more people take care of their own bodies and do the same for the planet. ❤
Here in Germany that was basic school stuff in Geology classes. I am sorry that in your country the education is so bad and corporate media is not helping.
well, you are watching PBS, the station that claims men can get pregnant. so I, as an educator, will do my part, the rest is up to you... you never hear about anything of value from mainstream news. the fact that you still don't understand this is why you are part of the problem. seriously, how long will it take for you to figure out you are being naive? not about climate change, but about science? 🤣🤣🤣
Yes. There is a lot of misinformation and disinformation published by several governments. In Canada, last winter I paid 52% tax on clean natural gas, yet there has been no improvement.
@@erictjones Atlantic meridional overturning circulation, in very simple terms warm salty water from the gulf travels north on top of the ocean bringing temperate weather to Europe, then as it cools as it is more salty it sinks, and it then returns south, even travelling beyond the equator and eventually joining with other major global water circulation patterns
As an Icelander, I'm just pissed that I'm missing out on global warming. Heatwaves everywhere IN THE WORLD except where I live, which sucks and is really unfair.
Well, Eysteinn (that's from "Einstein"?), it's called Iceland for a reason. Considered moving to... GREENland? Btw I live in Belgium and I do remember having seen a heatwave this year which doesn't mean that it doesn't suck for those who did. We had lots of rain though and very little sun, a bit like Iceland? Cheer up. You have invisible people, elves, trolls, sea monsters. We only have to odd tree person and missing drone.
There was a PBS Nova special from over a decade ago titled 'Earth From Space' that used data from multiple satellites and connected it all to show how inter-connected all of the ocean currents with air etc. really are. It was fascinating and I wish we could get an updated follow up! Thanks for all y'all do! :)
Scientists are looking at several indicators of an AMOC slowdown, eg salinity changes at various depths in the Atlantic. Some other indicators can be attributable to other climate change impacts, eg increasing sea-level rise & coastal erosion on the usa east coast, and the warming / drying of the Amazon rainforest etc. Whatever the current status of the AMOC, the only thing we can do to "fix it" is to reduce emissions. Eliminating human emissions is required for many other climate related solutions, so let's do that anyway.
"the warming / drying of the Amazon rainforest etc." That'll be slash/burn/bulldoze at play, not global CO2/warming. The Amazon Rainforest is doomed. It WILL reach its own tipping point through direct destruction. The climate extremists are happy for that to happen as they can blame Climate Change and tell that us we were warned...
That's the thing that deniers refuse to acknowledge: There are no downsides to eliminating our emissions and pollution. It's a very obvious win all around for everything involved.
I really do appreciate these videos! No one else seems to be covering such an important issue to every one on the planet. If it isn't politics or conspiracy theories, it doesn't get covered anywhere. Thank you for keeping it real! As for what I am doing? I'm planning on starting a food forest, not for me, but future generations. I had a tornado destroy a large chunk of the forest behind my home a few years back, I want to rejuvenate that strip with healthy new trees and vegetation that may help feed the future generations.
Yep. Because that's what Earth does with tipping points. She's the great equalizer and cares not about individual species, just the equilibrium of the planet. So, knock yourselves out, humankind.

Honestly my take away from this is that the earth has warmed more in the relatively recent past than it is now and that the planet seems to have built in temperature corrective systems. Oh sure it might be really bad for a lot of people but like the planet itself apparently isn’t gonna be inhospitable and it also seems unlikely this would devastate human civilization broadly. Mildly less worried about climate change after seeing this lol
Right now I am most excited about geothermal power. I just find it to be a very elegant method of producing energy. Just drill a hole deep enough, lower some pipes, add cold water and get very hot steam, run it through a turbine, use the remaining heat to heat homes. Together with wind, solar and a few flywheels we should be able to cover most of our energy needs.
In our area (west coast of Canada), they use geothermal for heating and cooling. It’s too difficult to drill deeply enough to produce steam, but it’s real relatively easy to set up enough temperature differential to heat homes in the winter and cool them in the summer.
I’m in Alberta, Canada and our government committed $50B to geothermal industrial development. We have a lot of oilfield drilling skill here, so it is a very exciting time for a lot of engineers and technicians here. Geothermal is a great fit for energy transition from on-shore oilfield work! Geothermal gets pretty complicated, as does anything 20 feet below ground or more: hydrology, rock formations, soil type, pressure/heat management, corrosion, etc.
Geothermal energy becomes truly practical with microwave rock vaporization drilling because then conventional fossil fuel power plants can be converted in situ by drilling supercritical boreholes for live steam extraction. This technology is very real and essential for the planet
As an advocate of ecosystem sustenance for all of life, I recommend that current agricultural practices change so that soils can rebound with native mycorrhiza and fertility, and so that ecosystems can revert to fully supporting native plant and animal species. Practices include water harvesting, sustainable grazing practices, keeping the soil covered with plants, permaculture and creating 30-50 ft. wild zones (akin to British hedgerows) between fields and property boundaries, and wider wild zones (200 ft or more each side of a river, lake or stream) in all riparian areas. These practices allow farms and ranches to become important carbon sinks which help curb climate changes and halt the diminishment of species. Also, ag practices of pesticide, herbicide and fungicide uses that damage internal organs and biological systems need to be halted to clean up waters and produce foods that are non-damaging to health. Ag practices need to reflect the climate in which foods are grown such that extra water and other resources are not necessary to produce foods. This will restore ground water levels and natural stream and river flows. Also these techniques utilize fewer fossil fuels which all add to global climate changes. In areas of higher wildfire dangers, goats and sheep need to be herded over these terrains every spring and summer to lessen the fuels and thin forests to make them less prone to catastrophic wild crown fires. Reducing catastrophic crown fires also counterbalances climate change.
Your right about working toward better agricultural practices to help the soil absorb carbon more efficiently. Check out the Carbon Cowboys project, seems promising.
We should restore swamps where we drained them for agriculture. They capture a lot of carbon into the ground, creating a fossil fuel from the atmosphere, basically reverse of what we're doing, so that would lead to a slowdown in carbon level rise
You mention a couple times that the cold blob "shouldn't exist" per models. I feel like Stefan's research and papers have shown that the cold is expected and its a current issue of the current models that they don't show it. In other words, it is expected and its exclusion is a known flaw of the models
I do wonder if it's a phenomenon similar to the La Niña currently in the Pacific that their infographics team is desperately trying to cut out of the thumbnail and at 0:08. I understand why they're doing that, but still it's very noticeable once you know we're cutting out half the Pacific because of a separate known 'cold blob'...
On one hand the climastrology cult says we'd be cooling into a glacial period if it weren't for our emissions. On the other hand we have the climastrology cult saying our emissions will cause a glacial period. Anyone that can think themselves out of a paper bag can see that climastrology is nonsense and is closer to religion than science - unfortunately our brainwashing centers we call an education system has taken away most people's ability to think themselves out of a paper bag.
At around 3:15, it says models estimate a 45% weakening of the AMOC by the end of the 21 century with low CO2 emissions, and 55% weakening with high CO2 emissions. Not much of a difference. Yet at 12:35 the intimation is that lowering our CO2 emissions will prevent AMOC collapse ...
I see the carbon fraud continues CO2 is not the problem and never was - ITS PLANT FOOD people!! This fraud is a way for Governments to tax and control the populous it is making some people very rich. This very program stated that 28,000 years ago IT was warmer then now! didn't see a lot of cars back then!!! The world has been colder way longer then it's been warm enjoy it while it lasts because Ice ages are very long and not any fun. The climate is affected by so many things like the Milankovitch cycles ...which includes the shape of Earth's orbit (its eccentricity), the angle that Earth's axis is tilted with respect to Earth's orbital plane (its obliquity), and the direction that Earth's spin axis is pointed (its precession). People have no problem understanding the four seasons but some how don't think the sun has much impact on our climate...REALLY. Fossil fuels are not the problem it's BAD science that is the problem, poor temp gather data, and global weather models that have never worked. WAKE up people the Carbon Fraud needs to end!!!
I don't think the take away is that "it's not that bad", it's more like "the way things are going, it's already too late to make a substantial change in the outcome". It's all just damage control now.
It is a shame that the consequences of burning fossil fuels were suppressed by those gaining money and power from the resource extraction. Had we been rational and used fossil energy with caution both humanity and the ecosphere would be in a much better place.
I do believe it could collapse. With all the negative impacts humans are still creating due to not wanting to change our way of life or can’t afford to do, it will reach negative consequences before any massive positive changes are put into effect. From my observations, I feel that those at the top want to squeeze every second of the money driven aspects of life before they switch to caring about the impact it has on our world. They will likely find a way to monetize things after it’s all collapsed.
Yeah of course they do, and this is only made worse by the fact that all the profits they make now will be worth NOTHING if we do reach a tipping point and it ends up causing an effective collapse of civilization. Because it's ultimately corporations and their fiscal revenues which run the world, not the politicians, they just pretend to.
Thank you for such an informative video, and thank you to the folks like bettergames6259 who in the comments explained what AMOC is-Atlantic Meridional Overturning Circulation. It is frightening to think that human stupidity, greed, arrogance, and disrespect towards the air, water, and land that supports and feeds us will result in the demise of many. If you overpopulate Earth which upsets the ecological balance, then the Earth’s ecological balance will do things to rebalance the scales. I agree that the movie “The Day After Tomorrow” is problematic; however, it is a movie. Still the most compelling line in that film comes to mind when I think about ecological imbalance-to quote Ian Holm’s character in the movie, “The Day After Tomorrow”: “Save as many as you can.”
Better normal rain than acid rain. Or fiery rain. Or earthquakes, monster storms and super-lightning. We still have it good, it's just depressing at the moment, not deadly. I mean hell, there's still the option to "opt out" before it gets really bad. In the future death may just come for you or any of your loved ones irregardless of what you do. So, my advice? Just quit yer whining, boy, and enjoy yourself some merry, rainy Christmas! 🎄🌧🌧
Thanks to the warming, I can ride a bike in Poland all year round. Quite a ride yesterday. I won't have to build up my form in the spring from the very beginning. 😅

@@timothyrussell4445 there is no evidence to support the fact that this increase in temperature due to massively increasing levels of carbon in the atmosphere is going to lead to a similarly fast decline in temperatures. What you doing is just wishful thinking. And even if true you're talking about a catastrophic drop in temperature which we don't want to happen either.
@@macmcleod1188 I was replying to spindryer - I agree with your point. No, modelling suggests the ice age will be very much localised to north west Europe; globally temperatures will continue to rise, especially in equatorial regions where heat will be trapped, the Southern Hemisphere will get warmer generally too. As for the catastrophic drop in temperatures in north west Europe, that will happen, and farming on the scale we require will not be possible in much of Europe; it'll be similar to Alaska
@timothyrussell4445 yes and the rain bands are already starting to move. They're about 50 to 80mi north of where they used to be. In fact the seed catalogs finally adjusted their climate zones on the packages to reflect the new reality. And they're moving on to areas that are less productive. Plus we're getting more extreme weather which isn't good for plants either.
My conclusion: we are doomed, not to extinction but to drasticly reduced quality of life due to extemes of climate, first heating that will displace large populations due to flood and fire and cause increased costs in goods and loose of insurability. (Later by the AMOC collapse perhaps) More imigration and reduced food and land resources leading to stresses on democratic institutions and less international cooperation. All favoring greater autocratic governments and more war. Humans will adapt but at a cost to civilization and population. Perhaps this is the "great population reset" needed for the next (22nd) century. This is based on 1) the fact that climate change first discussed in the late 1980's when atmospheric CO2 in 1990 was 354 ppm. This is now over 420 and rising every year by 1 - 2 ppm. In 1990, CO2 emissions totaled 19.5 GT. This is now over 36 GT. (Pre industrial atmospheric CO2 was 280, and emissions in 1940s was less than 5 GT) 2) during the covid year when basicly the entire world economic activity was drasticly reduced, the Amospheric CO2 continued to rise but at a slightly lower rate. CO2 emissions did fall by 1.9 GT between 2019 and 2020. But atmospheric CO2 continued to rise. 3) Humanity will not tolerate economic slow down of the covid years as a perminant condition. 4) even if we have Zero increase in emissions, because the half life of CO2 is measured in over a century,which means that for at least a generation or two, Climate change will continue. 5) feed back loop-processes progressing toward their feed back point: loss of arctic ice, wild fires (contributing to greenhouse gasses and soot spread by wind to fall on glaciers facilitating melt), and permafrost melting.
@@quickmythril2398 "We" refers to civiliized humanity as whole. As I said, suvival of the species is likely, just not at the levels of civilization we currently enjoy. regarding "more people die of..." current causes of death will be less relevant in a climate change future due to 1) increasing heat which whch will displace current cold, 2) delitarious effect on farming with displacement of rain fall areas, drought, flooding and fire, 3) and my biggest concern is diseasse due to either migration of tropical disease into current areas too cold to support them, or from melting permafront releasing a pathogen for which current immune systems are not prepared (especially fungus or virus).
@@granitfog what??? "current causes of death will be less relevant in a climate change future due to increasing heat which whch will displace current cold" ... uhh if there are deaths due to cold, and the cold is displaced, that means less deaths from cold. how is that not relevant?
If the AMOC collapses it is going to cool the planet? But that isn't good. As it seems only certain regions will experience shifts to a much colder climate. While other areas become hotter and dryer? Am I understand that correctly? Net zero emissions isn't going to happen. Fossil fuels are too heavily relied on. Even green energy is powered by fossil fuels for energy, manufacturing and delivering. We need a substitute for oil and we need it fast. One that is organic and has limited emissions.
The AMOC is a major current that transfers Heat from the Tropics to the Polar Regions, which helps keep the Global Climate stable. All the alternatives exist now, the Infrastructure just doesn’t exist yet so it’s not practical. We need State Intervention and we needed it decades ago
Without the current transfering heat, the bigger difference in temperature will cause even more common and catastrophic hurricanes. Or at least I think so, climate is complex.
@@Mr.MasterOfTheMonsters I think, as a person from southern india , ground water depletion with fractured ocean current means , effectively no more sense of winter from now about 20 years after in any sensible capacity. No more sensible water sharing mechanism within the water scarcity states. No more sense of recollection about climate and it's complexity. Pure wack.

This video is so wonderfully made. I like the way you present the Earth with interspersed storms throughout the world which all fit together like a puzzle piece with and result from things like the Amoc, glacial melting. So cool
@@kmoses582 It's exactly because the change has happened in only a few decades (and it's accelerating), that we should be alarmed. As you say, 50 years in geological timeframes is nothing, so that shows you how fast is everything happening.
@@kmoses582 I kno it shouldn't be but it's still surprising seeing someone denying climate change, try reading more & quit listening to biased sources
The New England and Mid Atlantic Coasts have been seeing signs of disruption in phytoplankton and this is directly related to the strengthening of the Labrador Current which has been bringer cooler than normal waters down the continental shelf. Ice melt from Greenland’s ice sheet is driving huge changes in the marine environment.
I live right in the middle of the Labrador current. Ice bergs have been floating by for tens of thousands of years. Bergs were written about when the Vikings were in North America. What was the cause of the Greenland ice shelf melt then?
@ I’m on 64 years old so I don’t know how it was 10,000 years ago but I’m positive that you are a world renowned expert in this, so you tell us sandpaper bc I’m not rough enough.
@@Upinthegarden Bergs come from glaciers/ice sheets reaching the coast, so more snow/less melting in the past would have made thicker ice sheets/more bergs. No melting then.
So 2 mile thick ice sheets melting between 15-12k years ago releasing enough melt water to raise global sea levels by 400' didn't cause the AMOC to stop but the current melting in ice sheets with indistinguishable sea level rise is causing it to stop. That is much like the melting permafrost consisting of preserved plant matter being a net carbon emitter rather than a net carbon sink despite the conditions being present that caused the plant matter to be deposited there in the first place providing the source of the carbon emissions now. Climastrology is cognitive dissonance, all the way down.
So.... I just want to get this straight. According to the professionals the earth has gone through these cycles without human intervention and human caused emissions over and over again... but somehow it's the human intervention that is causing it this time around?
The earth's climate is controlled by a set of natural variables. As those natural variables change over long periods of time the earth's climate adjusts accordingly. The issue today is that man is influencing one of those natural variables, and he exerts that influence via his use of fossil fuels
There are natural cycles. The major ones currently operate on 100,000 year timescales. The last 10,000 years has been remarkably stable, allowing human civilization to develop. But much of the preceding 90,000 years was characterized by major climate instability that would have disrupted any fledgling civilizations. Calculations suggest that our current *stable* climate could persist for another 10,000 years, but this stability is *fragile*. Theory and observation tell us that our climate system is 'twitchy', responding suddenly and unpredictably to perturbations. Rising global temperatures caused by greenhouse gases represents a major 'kick' to our climate system The physics is simple and clear. Regardless of whether CO2 has previously been a 'driver' of climate change in the past, or an 'enhancer' of climate changes triggered by other things, the 50% increase in CO2 over pre-industrial levels (to levels not seen in over 3,000,000 years) *will* perturb the finely-balanced energy budget of earth's surface. Nobody knows for sure what this warming will trigger, but we know enough to make educated guesses, and there are scenarios - like a slowdown/shutdown of the AMOC - that lead to a world characterized by rapid climate *instability*. Human society (and global ecologies) could adjust to gradual climate changes (centuries to millennia). But instabilities that can occur within years to decades would be nearly impossible to adapt to. The result would be chaos.
Yes Two things: 1- the earth going through those past cycles took millions of years. The cycle took millions of years of to slowly change BUT we humans are doing it in mere decades. The amount of change we are pushing into our atmosphere and world is off the charts. You can disbelieve or laugh at this but you might see it & finally understand in your lifetime (depending on your age & all that) 2- yep the earth changes, it’s changed before so no big deal right? WRONG !! When this changing happens crops won’t grow where they used to, massive food crops will be wiped out. Now growing seasons are being messed up, every year we hear more stories of “oh darn the Georgia peaches or Florida Oranges had the worst growing season ever because storms were very different than before”. Too much rainfall all of the sudden after weeks of drought lead to a massive reduction in ______ (fill in the blank crop this year). That story repeats again and again. The planet will go on. But YOU humans will have a hard time when the food can’t be grown as easily, when the food shortages lead to famine, war and chaos. But hey, you sound like the type of guy that laughs & scoffs at “the professionals”. What do they know. You were so smart in school. You do your own research. Good luck buddy.
@@EchoDoctrine Uhh there have been 30 glacial-interglacial cycles in the past 2.5 million years alone with many more interstadials in between. From 15-10k years ago the Earth warmed enough to melt major ice sheets in North America and Europe which resulted in 400' of sea level rise - if every inch of ice melted today the resulting sea level rise wouldn't even be half of that. Global crop production is at an all time high. Satellites and ground observations show a massive greening of the planet as higher latitudes warm and CO2 improves growth. The only thing you got right is that we ARE laughing - at you and all your simpleton climate cult buddies.
Yes. Greenland melting is exactly one of the causes of AMOC collapse. It disrupts the salinity/density/heat balances that allow the corculations to happen. This is known.
As I understand it from friends who are actual researchers looking at Greenland melt water, the reason the blob isn't predicted in models is that melt water hasn't been fully incorporated into the models. It will be after it's better measured, we hope.
@@leftcoastline Yes, the idea is understood. A quantitative detailed understanding is not yet very advanced, so putting the melt into models that use vastly intricate calculations and iterations can't be done very well yet.
the following is more serious than cynical, but there are a few things that have got me thinking: - If the AMOC keeps collapsing over millions of years due to global warming, without us, then how does us our CO2 materially change the cycle? - If the heating of the AMOC, thereby causing it's collapse, encourages global cooling, then what is the major concern of us being within an interglacial warming period, which again happens with or without us? - CO2 being the main input source for plants and green life on the planet is also produced through the natural breaking down of methane. Methane being the major output of biological decay, creates CO2 which is absorbed by plantlife, which create fruits/veg/nuts/pollen, etc, etc....and some of the largest zones for this are monsoon flood zones/flat-lands....is this show insinuating that we need to reduce floodlands used as a significant part of our delicate eco-system by reducing rainfall?? - Is it just me, or does the video really just confirm that the planet is in constant flux, and we (as a race bent on survival at any cost) don't want to face the inevitability of the next pending move in the constantly advancing natural global adjustment and are therefore striving for solutions to fight against nature ?? (that we basically cannot accept that the world is changing regardless of our efforts, and that we, in the delusional belief that our species is eternal, need to fix the planet???) I was always a bit 'on the fence' when reading how farming is a high carbon industry, when I also realise that vast acreage is destroyed on a regular basis for development of more industrial zones...the same green acreage that would have been absorbing the carbon output from farming.........natural carbon capture plants. This video about the AMOC , I think, just swung me into the inevitability of our situation, no matter what we do. Our collective output has a micro-fractional impact on the natural order of things, and coupled with the weakening magnetic field (which also causes heating through increased solar radiation) the next stage is coming, and mining heavy metals to create electric cars, flying fruits and vegetables all over the world, and recycling your tinfoil hat wont change a thing.
In the United States, the current war on science is getting worse, and education is also worsening. We have politicized this issue to the point that half of the US population feels it a duty to ignore the issue, even if they believe it is real. So as long as politics drives the conversation, there will never be enough consensus to do something about it in the US. The war on science can't be ignored, or swept under the rug. The war on science will prevent any successful outcome. We have a situation where we can't even ask these questions because politics doesn't allow a consensus.
Lol science is in the dark ages and climastrology is a big part of it. Ironically the brainwashing centers you call education has prevented you from having enough critical thinking skills to see the cult of climastrology for what it is.
Science doesn’t care for belief, it will happen regardless. Humans will need to be creative if we are to survive as a species if we can reach a point of disruption of the global climate in less then 200000 years of existence
i absolutely hate how they always boil it down to *only* carbon emissions. its a disservice to the subject to simplify the complexities of this system to put it down to only a single thing.
follow the money, everything about covid was, this is no different. My problem is just showing 20 years graphes then 150k year graphs to say we are in trouble? A thousand years is a blip on earths timeframe and dont care how good a geologist is but probably couldnt get the past right within 10k years.

Well, if you're gong to take that tack. The AMOC was probably non-existent once you get more than a few tens of millions of years in the past. Without an Atlantic Ocean, you have no AMOC. So, it's all good I guess?
@@stainlesssteellemming3885 yes, it's all good. there are major cycles in the earth, sun, and galaxy. humans are a speck of dust compared to all that. to pretend like we could influence it, is like trying to steer the titanic by paddling with a plastic spoon.
I dont think we really can. Most people don't want to change their behavior and that's the only thing that will save us. We can't wait for corporations or governments to do anything. The time for that was 40 years ago. People need to go vegan, reduce their emissions, and stop buying stuff they dont need. The average US Citizen can cut their emissions by nearly 50% with nothing but behavioral changes. As a country we could cut our climate impact by a similar amount without asking politicians to do a thing. These things could happen immediately. Unfortunately we have the mentality that "China is worse" which just kicks the can down the road. We have conservatives who still refuse to even acknowledge the problem exists. We have therapists telling everyone to go ahead and buy another latte because you had a hard day. The can is constantly being kicked down the road by everyone because accepting that we all have some responsibility is too depressing or too hard. It's sad. We're all responsible everyday we don't do something about it.
It does not matter how many facts you give some people, they will still ignore what is staring them in the face. Just look at the recent U.S. election.
Saltwater farming in desert coastal areas. Rain retention/reclamation systems in deserts like they are working on in India and parts of Africa. These create green areas which will also work as carbon sinks, and also keep those areas cooler.
Using Celsius and Fahrenheit in the same video and then referring to both as "degrees" is a pretty big fail for a science channel. It can get very confusing for people less educated in the subject. Just stick to C° and the metric system, they're the scientific standard.
If I am getting this correctly, you think that the AMOC is slowing due to global warming because of CO2 emissions, but once it slows or stops, the earth will begin the glacial cycle that is going to happen anyway and the earth will get dramatically cooler, affecting rainfall, which is going to come in areas previously not getting much creating more methane. If this is true, wouldn't this also prevent methane now rising fron areas where permafrost is thawing? Wouldn't cooler northern European temps also cause the Greenland ice sheet to reglaciate instead of melting? That sounds alot like a loop of warm and cool periods. One thing is obvious in this video, and that is the fact that we are nearing the end of a warming period that is a natural cycle and we still are several degrees temperature below the last warming cycle. I think the Milankavitch cycles are the most dominant factor while you never mentioned that at all, as if it doesn't exist.I suspect that the AMOC will cycle more rapidly if what your evidence provides is correct but will eventually reach a point where the Milankovitch cycles make it a permanent cooling until the next interglacial rather than expediting the next glacial period of the current ice age. Trust me, you do not want to see another deep freezing glacial period where the ice is many miles thick and most of earth is covered in ice, but history shows that it will happen. Humanity needs to plan for this with every modern technological advantage we can muster. I also do not trust any science that does not include the amount of CO2 produced by breathing animals such as 8 BILLION humans. I need to see and hear from scientists who account for all factors rather than just CO2 and wild predictions that exclude all other factors. For example, If CO2 that represents about .04% of the current atmosphere is such a driving factor, what caused the melting of the glaciers before mankind even existed? Where did such an enormous amount of CO2 come from to cause warming enough to cause the current interglacial warm period? The answer is there, but scientists affiliated with the IPCC are not interested in anything that could stop cash flow to them and their never ending studies on CO2. They really should get to the bottom of what created all warming and cooling periods.
"I think the Milankovitch cycles are the most dominant factor". I agree. Plus, the ice core data shows that when the temperature drops, due to the Milankovitch cycles, the ocean dramatically absorbs much of the CO2 in the atmosphere. By destroying the entire fossil fuel industry, our ability to put some CO2 back to keep the planet warm is gone.
It is colapsing, the coral reefs are dead bc the sea is 6*C warmer than 15 yrs ago, the sargasso extends almost all over the atlantic during the summer....There is NO wind. Drastic changes about to happen, perhaps 2030(?)

Just one thing, you keep mentioning fahrenheit, a uniquely American thing... why not use a measuring method that is used as standard by the scientific community globally, as well as about 99% of the planet... celsius?
Perhaps because the US has one of the highest concentration of climate deniers on the planet? In which case, you want to frame the data in terms they are familiar with.
Because Fahrenheit is more precise, scaled for normal temperature variation at the planet surface, invented just for that purpose, by the guy that invented the thermometer.
You might want to ask Mr. Orange what the AMOC is and how his proposal to drill for more oil, coal and gas might tip the AMOC. Then again, corporations will just keep on going, as long as there is profit to be made. So, start preparing your survival communities today because its gonna be a long, long,long cold period.
the doubt about amoc collapse will not survive the 2050's. the impotent political machine of the old world will not avoid this catastrophe of our own making. the old system is and must collapse so future generation can build with lessons learned. who can we blame? it is our own persistent ignorance that is the cause 🙂
extreme climate alarming. Climate is an issue but not in the top 5 for humanity. Wind and solar subsidies bleed resources for a non-solution. the hope is that humans will nor manage to pull-off large scale climate meddling and natural fluctuations will take over from there.
In my book political isms should not be a part of the task to get our world transitioned to an emission free energy production and usage. No matter if anyone are on the left, centre or right political spectrum, they need a planet with clean air to breathe, waters that are healthy and filled with life and an unpolluted landmass to live on. Glaciology now scientifically have documented our atmospheric carbon content, YEAR BY YEAR 1,1 million year back, thus we know the conditions that paved the way for our creation. It is in itself remarkable that we can do that, considering it´s only 65.000 years since we left the African continent for the first time. This insight have told us, that there have been cyclic slow climate changes happening before but that these have not really affected the atmospheric carbon content much. However 3 times in the 1,1 million years, large widespread global volcanic eruptions have made sudden changes in our atmospheric carbon content with up to 30 PPM over the otherwise relative stable 220 PPM the planet´s regulating systems prefer and try to seek back to, and EACH time it have triggered abrupt climate change. Since around 1880 and until today we humans have caused the atmospheric carbon content to go up with over 200 PPM! Our atmospheric carbon content do not care what corrupt people agree behind closed doors at shady meetings, it´s simply responding to the massive amount of greenhouse gasses we spew out. In this very matter we all are in same boat. I am a strong believer in democracy. The problem I see in to many nations that call themselves democracies, seem to be that the fossil fuel industry have managed to corrupt politics and those operating in politics, in ways that have short circuited democracy, helped by a media landscape supporting the lies and dis and mis-information. I do not think it are a coincidence that the 4 nations where Murdoch media have significant market shares, Australia, USA, Canada, UK also are the large nations with highest greenhouse gas emissions per capita. What we globally should be doing RIGHT NOW is to be in the middle of an "Apollo program" effort to make a fast transition to emission free energy production and usage, simply driven by our understanding of the urgency our current situation dictate. It would, on top, create massive growth and prosperity around the world but do so sustainably and provide the foundation for a circular economy. If we do not urgently get our planets temperature down, we have entered the beginning of the end of a world remotely recognisable, to what we know, will allow humans, the species we share the planet with, the fauna in air, on land and in our waters to exist. Mars lost it´s atmosphere and in the end, the same can happen here, although I suspect we will be long gone by self eradication before. The future that have begun will come with massive random disruptions caused by extreme weather and it will randomly take away peoples livelyhood and traditional living conditions. WE NOW have ALL the knowledge and technology needed to make a complete and fast transition to an emission free energy production and usage. Our grandparents can be excused since they did not know the consequences of their actions. Our parents should be ashamed for not acting in time but WE have full insight and the solutions and thus we truly now act as the ultimate morons. If there will be any left to write history books we rightfully will be judged harshed. Name one other mammal that knowingly and deliberately destroy the very habitat that provide the foundation for it´s existence. Our house IS on fire and currently the consensus seem to be that massively pouring fossil fuels on the fire miraculously will make the fire go away. As normal human beings, WE MUST NOW INSIST politicians, no matter from what spectrum, are able to present a plan for making own nation carbon neutral FAST!
The world is already changing dramatically. This year had so many unnatural disasters. Rainfalls killing thousands in the Sahara desert, Spain, Dubai etc‼️
The floods in Dubai were because of manmade cloud seeding and in Spain was due to a canal being diverted and even if that wasn't true flooding has always happened anyway...
I’m from the UK and what terrifies me is that after 10 or so years of looking into renewable energy sources and finally seeing the light on moving away from fossil fuels some countries are starting to get governments that are climate change denier’s and want to reintroduce our reliance upon fossil fuels. However there are also some countries that are more than happy to buy Oil, Gas and poor quality coal from countries that are under restrictions and are exporting to countries like China, India and some Eastern European countries which are getting these fuels at a discounted price. Wa also have countries that have a vested interest in selling fossil fuels to stay rich and relevant energy providers. For example Russia is currently producing some of the dirtiest coal in the world and exporting it to whoever is willing to buy it at a huge cost saving, however the countries that are buying it are using it to produce cheap electricity for their expanding energy requirements for their expanding economies. Until the world is willing to invest in renewable energy we are just going to destroy our environment and by then it will be too late. Heck even the UK no longer uses coal to produce electricity.
There is no "too late" in this discussion my friend. Look, it is UNDOUBTEDLY true to say that mankind has INADVERTENLY geo-engineered himself into a corner with his use of fossil fuels, but it is also true to say that mankind can PURPOSEFULLY geo-engineer himself out of that corner as well. Will the road be a little bumpy? Sure, but man made climate change is NOT going to be the end of the world. We have added a lot of carbon into the carbon cycle, and yes that is warming the planet some, but at the same time we can also work to remove that carbon from the carbon cycle which will in turn cool the climate back down. Relax, things will be fine.
I think humans don't understand the complexity of the earth's climate. We have such a limited scope of understanding of the earth's climatic history that we are only making speculative conjecture based on only a small historical window of comparison. It can't be denied however, that humans have a larger negative impact on the climate with more than just c02 emissions, but deforestation, general chemical pollution, and habitat destruction. Those are the major issues causing climate change. Me not driving my car isn't going to stop climate change, implementing strick environmental regulations on companies and governments is the answer. Not allowing the creation of toxic chemicals and not allowing widespread habitat destruction is the answer.
Every time you burn just one gallon of gas in your car/truck, you add 20 pounds of CO2 to the atmosphere where it will remain for centuries. Every tankful of gas adds 200-1000 pounds of CO2 to the atmosphere, so yes, us driving and heating our houses with fossil fuels and eating meat (especially beef) are all part of what is causing the climate crisis.

That cold spot near Iceland explains why they were significantly colder last winter. Reykjavik never got that cold when I lived there from 1986 to 1988.
I find it odd that we are being shown how all these patterns have occured naturally many times before, but then being told that this time it's our fault and we can do something to change it.🤔
the graph at 10:31 looks really scary. That abrupt change at the end is so extreme and unnatural that the conclusion is that the AMOC collapse will be not only inevitable, but very fast and even more extreme...
It’s like when your house is on fire and instead of putting the fire out we are discussing if the fire will destroy the house. Pure madness, we need systemic change.
Unfortunately we're likely to reach 3 degrees before 2050 or even before, not 2100. We've already passed 1.5 degrees this year and we're accelerating drastically... This year alone we jumped over 0.1 degree. more than all the 80s combined.
One of the things I'm personally doing is creating water harvesting earthworks in Greece! We are about two weeks away from planting out our food forest. When the swales are full, we can slow, spread and sink 50,000 liters / 13208 gallons of water, recharging the aquifer after giving a good drink to our fruit trees. I am also planting a whole bunch of support species such as acacias, vetiver and willow in order to create biomass that will further absorb carbon.
I'm very curious as to what these water harvesting earthworks are! I'd love to hear more about this. I'll do some research myself but thank you for the guidance!
Shame it is too late, just like this episode.
+10c equilibrium already locked in.
@@JBaxter-pi8oj Most water harvesting strategies are to control and reduce the surface flow by topology and permeable materials. The idea is to let the water soak into the ground to rejoin the shallow underground acquifers rather than erode the surface and flow away. Swales are basically channels of rocks and pebbles into which the water would flow and it's speed reduced as well as directed into low lying areas where it should soak in, think of them as a French drain or ditch. In India, there's an ancient practice of piling up the soil in chevrons against the natural flow of the water on the surface so they slow down and have a chance of soaking in. If we used permeable pavements on our streets, sidewalk and driveways, a lot more water would soak into the ground to replenish the aquifers. Of course, these are just the shallow aquifers and hence more likely to absorb pollutants. Permeable surfaces are certainly important but offers little mitigation against the probable climate changes from a cessation or slowdown of the AMOC and an AMOC slowdown would likely result in more snow and frozen soil moisture accumulation in the northern hemisphere as less heat is brought north hence the benefits of shallow aquifers accumulation might actually become a moot point. Shallow acquifers aren't really sufficient to buffer the changes in precipitation and snowmelt, it's just something we could do something about. By all means, we should try to harvest water wherever we can but really it has little benefit with AMOC concerns.

I'm an oceanographer. My research was done in the arctic ocean studying sea ice and heat budgets. The concern about AMOC slowing is what it means for the southern ocean. The conveyor belt (as it is colloquially known as) is more than a heat distribution mechanism for the planet. It also distributes nutrients. As AMOC sinks, the North Atlantic Deep Water (NADW) forms. This flows southward and eventually starts to upwell in a region called the Antarctic divergence. This upwelling brings in nutrients that in essence fuels the southern ocean's food web. This is why it is so productive and you have all the krill, baleen whales, orcas, etc, etc. A slowdown in AMOC will result in a slowdown of nutrients upwelling adversely impacting this ecosystem.
HOWEVER, recent research have revealed what the potential mechanisms for a complete collapse of AMOC would look like. It is not just the melting of Greenland's ice. This melting does indeed slow down deep water formation. But to completely stop deep water formation, a sudden large volume injection of freshwater needs to happen and happen quickly. Melting of Greenland's ice does not achieve this. As the ice melts, there is mixing, the fresh water gets entrained, but regional currents move this water westward (causing sea level rise along the eastern seaboard of North America). What these new researches found was when a huge amount of ICE breaks off from Greenland, then carried south by currents where they then melt at once, it is this shock to the system that can stop deep water formation. As Greenland's ice melts, the likelihood of huge chunks of ice breaking off continues to decrease. Therefore, this mechanism is unlikely to occur. To determine and measure this mechanism, the researchers used isotopes of Thorium to make these assessments.
A second mechanism is a sudden flush of freshwater into the North Atlantic. About 13k years ago, there was a lake in North America called Lake Agassiz. It formed due to the ice sheets melting back. Then around 12k years ago or so, there was a sudden influx of this freshwater into the North Atlantic and it is thought to have contributed to the Younger Dryas era where ocean circulation was disrupted and planet wide temperatures cooled considerably. (This is the 12k years ago period referenced in this video).
There is a possibility for a similar situation happening today. In the arctic ocean, there is the Beaufort Gyre. It is an anticyclonic (clockwise) gyre which means there is a concentration of water in the middle (with subsequent downwelling). Due to increased riverine inputs, increased precipitation, loss of sea ice, there is a buildup of freshwater in this gyre. A new oscillatory system, the Arctic Dipole (of which I was a part of in discovering and describing this system) controls whether or not sea ice continues to flow within the arctic ocean or is pushed out through the Fram strait. Right now, this freshwater buildup is contained. If conditions change and become just right, this freshwater in the arctic ocean can be rapidly introduced into the North Atlantic. This would be the necessary shock to stop deep water formation. This is what people need to be keeping close tabs on.
I do have my own channel here where I discuss many of such topics and have posted recent videos of this over the past several months.
First i was relieved that a collapse is not possible and then you hit me with Beaufort Gyre
So I should infer that a collapse could be beneficial as it may trigger a global rapid cooling of the poles while a heating of equatorial regions. Though in the short to medium term this could dramatically disrupt food cultivation as it will eliminate monsoons until the system basically self resets after the rapid cooling period. The issue is with our current rate of additional heating, does this offset the collapse? Can offsetting the collapse and reset actually present more of an issue towards long term survival than that short period of rapid cooling and disruption to food cultivation resulting in the same collapse but at a point where the rapid cooling doesn't take effect due to the excess heating. (Facts to be observed, if AMOC collapses, poles will rapidly cool during their winter periods due to the massively reduced sunlight; the counter will happen at equatorial region as it will begin to rapidly warm and not be regulated with precipitation taking places that are naturally well suited for farming to become deserts (given enough time))

Back in 2015/2016, I was part of an Internnational Arctic Circle Traverse team. We setup the largest Firn Compaction network in history - 13 sites across the entire Greenland icesheet. We were trying to help NASA determine why we were experiencing a significantly accelorated melt beyond what the current models had predicted. We setup data stations, did firn compaction readings, setup Thermister strings 65 feet into the ice sheet, multiple ice core samples at each site, did vacuum measurements, setup radar to track the ice melting through the ice layers, chemical anaylsis of each core back 30 years (10 cm chunks), checked surface reflectivity, and monitored each site's movement using hyper-sensitive GPS tracking. We confirmed there were giant shelves of monophorus ice that were stopping the snow from being absorbed into the sheet and forcing the new melt water to exit off the the icesheet on the surface instead of it's normal absorbtion cycle. We did the same chemical measurements on our ice cores (going back 30 years).
Wow. Thank you for this interesting info. QUESTION. In your opinion, WHAT ARE THE LONG-TERM RAMIFICATIONS OF YOUR FINDINGS?
So?
ive seen this amazing work, bravo to you all. be well thank you all
@@OkieJammer2736 This is a long-winded answer because the effects are complex and ripple across the globe in multiple ways. Firstly, the arctic ice sheet won't be able to repair the ice lenses that have formed for decades to come. That damage has already been done, to be frank. Time and carbon polution-reduced atmosphere is the only healer. Locally, the ice sheet is "super lubricated" underneath causing faster movement combined with significant 7x normal run-off. The core damage is already done. We are already seeing some of the effects in increased and stronger weather events due to increased and more frequent carbon overloadiing of our oceans and in turn, clouds absorbing more warm air over the oceans. The most critical effect of the ocean's warming is the effect and ripple effect of it's effect on plankton, the ripple effect on the ocean's food source for much of what the ocean's creatures eat and also it's affet on land animals. Ocean's water levels in the southern hemisphere will increase due to the moon's gravitational force on our ocean. We expect the shifting jet streams to cause instability in weather causing incereased and exagerated droughts. The human effect - Currently, we have a problem of human ego (We can't possibly be affecting the entire planet. This is a normal cycle that can't be stopped.), Greed (Oil and Gas and iit's industries spreading misinformation to distract from it's affect. It's the cows, volcano's, etc that are the poluton. Not us. Don't look here). Ignorance (It's not warmer here. It's colder. The ocean looks the same to me.). What we choose to do as a species will either allow us to recover from what we have already done, or feel earth's inadvertant wrath, to be blunt. The two major absorbtions of carbon polution are trees and the ocean. It's not enough to simply use more effecient forms of energy that are available. How quickly we respond to this crisis will exponentially affect the future generations of everything, either positively or negatively. The ice lenses will eventually be buried deep enough into the Arctic icesheets and lose their effect on the water loss. However, that process can't even start to happen until we reach a balance point of the oceans' and trees' ability to absorb the excess carbon.
@@hilltiggerWow, very well said. I understood, clearly what you were saying. Thank you.
I'm reminded of people who downplay the problem of climate change by saying "The climate has changed in the past!" Yeah. We know. That's how we know what it'll do, how we know how awful it is for us, for it to change now, as fast as it is changing. How those shift events in the past, even as slow as they were, devastated ecosystems and caused mass extinctions. How going as fast as it is now will be so much worse, giving life so very little time to adapt, to say nothing of our civilizations and how dependent we are on the climate staying the same with where we live and how we grow our food.
This isn't a difficult concept!
Its the speed of change that is deadly. Fastest rate of change in at least 380,000,000 years! Seems like a lot of people are going to ignore it till that becomes impossible. Then blame it on weather weapons and polority switch.

As a scientist studying AMOC (and in agreement with those scientists who did not want to be interviewed - I’m pretty sure I know who they are), I found this report to be highly biased. Yes, some climate models indicate a 50% slowdown, but just as many indicate no significant change. And higher-resolution models which get the physics of the Southern Ocean and eddies correct don’t suggest much of a slowdown. And AMOC is controlled as much by physical wind-driven upwelling in the Southern Ocean and tropics that is not modeled well in many low-resolution climate models. Also, the idea of a “collapse” comes from model runs in the 1980s that were significantly biased because the salinity and temperature of the North Atlantic was not close to correct. I suspect many people referencing the paper as proof of a “collapse” have never actually read it.
Look it up yourself and decide for yourself. Manabe and Stouffer (1988) Two Stable Equilibria of a Coupled Ocean-Atmosphere Model. Journal of Climate, Vol 1, pp 841-866.
But isn't the whole point that the patterns emerging in the temperature anomalies of the North Atlantic are reminiscent of the cooling patch that an AMOC slow-down would produce. This is *despite* the (modern) model predictions suggesting that no major AMOC slowdown should be happening at our current warming. We both know that models are not perfect and unrecognized model biases could mean that we've underestimated the sensitivity of the AMOC to perturbation. If this is true (and I agree - it's early days in trying to determine from short noisy observational datasets if this is indeed what is happening), then a major slowdown of the AMOC could have big consequences over the coming decades.
I'm of an opinion (not asked for assuredly) that a great chastisement is about to be poured out upon mankind. This is but 1 facet of the catastrophe cycle. The sun, the earth's weakening magnetic field, the approaching WWIII, diabolic influence in global society, etc; are examples of equally important other facets influencing our future. Morality is the hidden sign, as it decreases danger increases. This is human history and no one notices.
Citing one 1988 paper as evidence is totally absurd in the context of a research that flourished in the last decades
I'm curious about your thoughts concerning potential effects from the Beaufort Gyre. If the Gyre collapses, it could dump a large amount of fresh water into the North Atlantic.
Thank you for your insight and the reference.

An article in Scientific American magazine (1970's?) explored the science behind the 'radiosonde' buoys used to map ocean currents.
This mapping program was to determine transitions in temperature, salinity and other factors.
The authors stated that such transitions were natural 'hiding places' for submarines....sound waves bounce or are refracted by said transitions.
Regular mapping of the currents was necessary, as they changed over the seasons.
Almost as a footnote, the author noted a weakening in the 'transporter current' that kept central Europe from freezing.
'They' saw the trends over 50 years ago, hid it under Defense.
It's called a Thermocline.

this happens no matter what its how the earth cools it self down. technically we are still in a ice age. watch the beauford gyre once it is let loose its on
I thought that AMOC stood for the Atlantic Mid-Ocean Current. I was incorrect. It actually stands for the Atlantic Meridional Overturning Circulation .
Good video, Really don't like the chart at 12:09 . It is 2025 and we are still increasing our CO2 emissions year on year, yet that chart shows a dramatic slowdown, starting at 2020. Lets be real, we are never going to drop emissions and definitely not within the next 4 years. That chart needs to start at 2030 to be at all realistic.
We won't do anything in 2030 either but experience civilizational collapse
Dont worry about the chart bcuz we wont ever reach net zero. Billionaires own the world and they dont give a shit about anything or anyone but being the first a hole to be a Trillionaires.
In addition the only reason we had a dramatic slowdown was because of COVID and businesses converting to work from home wherever they could. The dramatic reduction in traffic was why we had dramatic reduction in pollution.
Humans won’t generally accept the facts because it would mean them being much more frugal - no flying, no SUVs, nothing luxury, no global goods, although it would be better for everyone.
@@StefanoCap13 I can't be sure if you're being serious or joking, but an interesting fact is that the fossil records don't show a mass extinction event or a large shift in the climate when the magnetic field last switched. And it's weakening because it's on its way to flipping, so magnetic north would be where today's magnetic south is. As it's one of the things we humans haven't obviously messed up on this planet I'm fine with it being a novelty so far.
Reducing emissions is only part of the solution. I'd like to see a show on reforestation of land and sea. By planting and nurturing kelp beds, sea grasses, and mangrove estuaries, we can remove carbon at the same time. A similar thing happens on land. But we know that it takes about 25 years for a newly planted forest to sequester more carbon than it emits. So we concentrate on prairie grasses, regenerative agricultural practices, and selective logging and replanting.

What are you trying to solve? It's not clear to me that there is an actual problem with the climate at the moment. We were probably closer to the truth in the 70s when we feared the next ice age.
Don't get me wrong, humans got some problems with environmentalism, like monocropping, glyphosphate, land use, etc etc ... CO2 is not likely a problem. Tippinging points likely cause a correction back to the normal state of the earth, which seriously more icy cold than anything.
Besides, look at CO2 atmosphere concentrations. Everytime they get high.... An ice age comes and they drop. It's almost as if the CO2 concentration _causes_ the ice age to occur.
@@kayakMike1000 It's interesting that you think CO2 isn't a problem. That sounds like the misinformation/ disinformation the oil/ gas industry is putting out. There is very clear evidence that CO2 is a problem. However, you are correct in that it isn't the only problem. From my understanding of this the programme is interested in is finding out (a) if there is a collapse imminent and (b) what the outcomes of that collapse could be. So it is limited to that particular issue.
Reforestation is an excellent idea as it allows nature to take the lead in healing itself. I believe the Japanese experienced the results of deforesting an island that was previously rich in organic matter and the effects of deforestation were that the land could no longer produce "food". Interestingly, it also impacted the ocean in the vicinity. And that included marine life. I recommend the work of Dr. Suzanne Simard, Julia Beresford-Kroeger and Peter Wohlleben for further information.
But can we keep up with the rate of emissions? I mean, if I'm not wrong, the Amazon forest removes from the atmosphere about 2 gigatons of CO2 each year, but we emit like 38, which are 19 amazonias each year. I know that I'm not accounting for biomass etc but my point is that the amount of CO2 we are emitting is no joke. Your approach feels "too slow" proportionally speaking.
And if we account for biomass, according to chatgpt the amazon stores like 900 gigatons of CO2 at most, which equals to 25 of emissions at the current year. In other words, we would need to create four full replicas of the amazonia each century to keep up with the rate of emissions.
11:00 - So... what were the consequences of the last AMOC collapse during the last interglacial??? The video explained what the blob indicates but didn't take a further step to explain the consequences of an AMOC collapse during an interglacial period beyond "it's a tipping point and stuff will happen". Will the AMOC collapse still have a cooling effect similar to previous glacial periods or will the effect be different now, given we are in an interglacial period?
You can't apply logic to a religion based on cognitive dissonance.
6:53
None of the interglacial periods last long, so either way it indicates it will cool again.
Thank you for this series. I am closely watching weather developments because I don’t want to be caught off guard by ‘unprecedented’ patterns and events. I’m trying to harden my home against the extreme events that might occur in my area during my lifetime (which is unlikely to last beyond 2060). I concentrate on this because it’s the only tangible thing I can influence. I don’t expect emissions to decrease until the number of emitters decrease, both consumers and producers. How that’s going to play out is still an unknown - probably a combination of the chaos caused by extreme weather direct damage and climate refugee indirect impacts. There is no evidence to date that individuals and countries are willing to voluntarily reduce their levels of consumption (aka ‘standard of living’) - and considerable evidence to the contrary. Most disappointingly, it appears that democracies are particularly hostile to needed changes.

👍
i mean the changes you just labeled as needed is the control of who can and when they can propagate. no human ever will purposefully decrease the standard of living they have. so ther fore like you say the only thing that can fix it is the reduction of consumers and producers ie killing off humans or controlling the replacement of those humans when they do pass away.
at the end of the day thats a dystopian society no one wants. well i shouldnt say no one as there are many people out there who wish to control society. i do have one question tho if you have a dot graph how much data do you need to come up with a conclusion? cause the dot graph we have for our weather history has just started and seeing people jump to conclusions about patterns that cant even be seen as the amount of data we have is not near enough is insane to me.

I never would've thought that the AMOC was critical for monsoon seasons in China and India. I thought the AMOC was just a North Atlantic climate thing only.
Water has an incredible ability to absorb and transport heat. The AMOC carries gargantuan amounts of heat from the tropics to near the polar regions. Now, warm surface temperatures cause air to warm and expand (becoming low pressure regions). Cold surface temperatures cause air to cool and contract (becoming high pressure regions). Air tries to flow from high pressure regions to low pressure regions, which results in our winds and weather.
When you change the AMOC, what you do is cause a major change the pattern of surface temperatures. Changing this pattern of temperatures changes the location and direction of winds, and therefore changes the location and strength of things like rainfall regions. These effects can occur far away (literally on the other side of the planet) from the north Atlantic.
The oceans have impacts around the world, little if anything is isolated. That's why you hear about El Nino and La Nina near the equator having precipitation and temperature impacts thousands of miles away since it can change the air circulation patterns.
I appreciate that you are centering the health of the planet. Your visualizations are impactful. It helps us see how the planet is alive- breathing and circulating nutrients through its oceans and air over land. These circulations are vital for its health. It is our responsibility as human beings to take care of our planet and manage its healthy function-like we ought to do for our own body.
I wish more people take care of their own bodies and do the same for the planet. ❤

Scientists are looking at several indicators of an AMOC slowdown, eg salinity changes at various depths in the Atlantic. Some other indicators can be attributable to other climate change impacts, eg increasing sea-level rise & coastal erosion on the usa east coast, and the warming / drying of the Amazon rainforest etc. Whatever the current status of the AMOC, the only thing we can do to "fix it" is to reduce emissions. Eliminating human emissions is required for many other climate related solutions, so let's do that anyway.

As for what I am doing? I'm planning on starting a food forest, not for me, but future generations. I had a tornado destroy a large chunk of the forest behind my home a few years back, I want to rejuvenate that strip with healthy new trees and vegetation that may help feed the future generations.

Humans: We can't slow down the warming, woe.
Earth: time for a force reboot on this temperature spike.
Yep. Because that's what Earth does with tipping points. She's the great equalizer and cares not about individual species, just the equilibrium of the planet. So, knock yourselves out, humankind.

Kind of cool to think that the Earth has a restart switch it seems to prevent extremes in either direction though
The earth was a ball of ice at one point and was 1 jungle at a anothere. So i do not think so.
Or... it's extremely unstable and small changes in atmospheric composition and temperature can wipe out most of the life on earth
It has, but it could happen very fast, making a very sudden shift and everything has a high chance to die
Honestly my take away from this is that the earth has warmed more in the relatively recent past than it is now and that the planet seems to have built in temperature corrective systems. Oh sure it might be really bad for a lot of people but like the planet itself apparently isn’t gonna be inhospitable and it also seems unlikely this would devastate human civilization broadly.
Mildly less worried about climate change after seeing this lol
I guess that depends on your age.
@ what’s my age got to do with it?
Right now I am most excited about geothermal power.
I just find it to be a very elegant method of producing energy. Just drill a hole deep enough, lower some pipes, add cold water and get very hot steam, run it through a turbine, use the remaining heat to heat homes. Together with wind, solar and a few flywheels we should be able to cover most of our energy needs.
We need wave action generation as well.
In our area (west coast of Canada), they use geothermal for heating and cooling. It’s too difficult to drill deeply enough to produce steam, but it’s real relatively easy to set up enough temperature differential to heat homes in the winter and cool them in the summer.
I’m in Alberta, Canada and our government committed $50B to geothermal industrial development.
We have a lot of oilfield drilling skill here, so it is a very exciting time for a lot of engineers and technicians here. Geothermal is a great fit for energy transition from on-shore oilfield work!
Geothermal gets pretty complicated, as does anything 20 feet below ground or more: hydrology, rock formations, soil type, pressure/heat management, corrosion, etc.
Look at New Zealand. 90% of the country is powered by renewable energy. Geothermal is big down here along with hydro and wind.
Geothermal energy becomes truly practical with microwave rock vaporization drilling because then conventional fossil fuel power plants can be converted in situ by drilling supercritical boreholes for live steam extraction.
This technology is very real and essential for the planet
As an advocate of ecosystem sustenance for all of life, I recommend that current agricultural practices change so that soils can rebound with native mycorrhiza and fertility, and so that ecosystems can revert to fully supporting native plant and animal species. Practices include water harvesting, sustainable grazing practices, keeping the soil covered with plants, permaculture and creating 30-50 ft. wild zones (akin to British hedgerows) between fields and property boundaries, and wider wild zones (200 ft or more each side of a river, lake or stream) in all riparian areas. These practices allow farms and ranches to become important carbon sinks which help curb climate changes and halt the diminishment of species. Also, ag practices of pesticide, herbicide and fungicide uses that damage internal organs and biological systems need to be halted to clean up waters and produce foods that are non-damaging to health. Ag practices need to reflect the climate in which foods are grown such that extra water and other resources are not necessary to produce foods. This will restore ground water levels and natural stream and river flows. Also these techniques utilize fewer fossil fuels which all add to global climate changes. In areas of higher wildfire dangers, goats and sheep need to be herded over these terrains every spring and summer to lessen the fuels and thin forests to make them less prone to catastrophic wild crown fires. Reducing catastrophic crown fires also counterbalances climate change.
Your right about working toward better agricultural practices to help the soil absorb carbon more efficiently. Check out the Carbon Cowboys project, seems promising.
How does all this create shareholder value.
Ever increasing shareholder value that is.
Wouldn’t this lead to an escalation in food prices for all. I guess we’ll have to all get community gardens again then. Fine by me 😅
We should restore swamps where we drained them for agriculture. They capture a lot of carbon into the ground, creating a fossil fuel from the atmosphere, basically reverse of what we're doing, so that would lead to a slowdown in carbon level rise

You mention a couple times that the cold blob "shouldn't exist" per models. I feel like Stefan's research and papers have shown that the cold is expected and its a current issue of the current models that they don't show it. In other words, it is expected and its exclusion is a known flaw of the models
I do wonder if it's a phenomenon similar to the La Niña currently in the Pacific that their infographics team is desperately trying to cut out of the thumbnail and at 0:08. I understand why they're doing that, but still it's very noticeable once you know we're cutting out half the Pacific because of a separate known 'cold blob'...
On one hand the climastrology cult says we'd be cooling into a glacial period if it weren't for our emissions. On the other hand we have the climastrology cult saying our emissions will cause a glacial period. Anyone that can think themselves out of a paper bag can see that climastrology is nonsense and is closer to religion than science - unfortunately our brainwashing centers we call an education system has taken away most people's ability to think themselves out of a paper bag.

Great overview of this very important component of global ocean circulation and our climate.
I do believe it could collapse. With all the negative impacts humans are still creating due to not wanting to change our way of life or can’t afford to do, it will reach negative consequences before any massive positive changes are put into effect. From my observations, I feel that those at the top want to squeeze every second of the money driven aspects of life before they switch to caring about the impact it has on our world.
They will likely find a way to monetize things after it’s all collapsed.
Yeah of course they do, and this is only made worse by the fact that all the profits they make now will be worth NOTHING if we do reach a tipping point and it ends up causing an effective collapse of civilization. Because it's ultimately corporations and their fiscal revenues which run the world, not the politicians, they just pretend to.
great video
Thank you for such an informative video, and thank you to the folks like bettergames6259 who in the comments explained what AMOC is-Atlantic Meridional Overturning Circulation. It is frightening to think that human stupidity, greed, arrogance, and disrespect towards the air, water, and land that supports and feeds us will result in the demise of many. If you overpopulate Earth which upsets the ecological balance, then the Earth’s ecological balance will do things to rebalance the scales. I agree that the movie “The Day After Tomorrow” is problematic; however, it is a movie. Still the most compelling line in that film comes to mind when I think about ecological imbalance-to quote Ian Holm’s character in the movie, “The Day After Tomorrow”: “Save as many as you can.”

@@timothyrussell4445 there is no evidence to support the fact that this increase in temperature due to massively increasing levels of carbon in the atmosphere is going to lead to a similarly fast decline in temperatures.
What you doing is just wishful thinking. And even if true you're talking about a catastrophic drop in temperature which we don't want to happen either.
@@macmcleod1188 I was replying to spindryer - I agree with your point. No, modelling suggests the ice age will be very much localised to north west Europe; globally temperatures will continue to rise, especially in equatorial regions where heat will be trapped, the Southern Hemisphere will get warmer generally too. As for the catastrophic drop in temperatures in north west Europe, that will happen, and farming on the scale we require will not be possible in much of Europe; it'll be similar to Alaska
@timothyrussell4445 yes and the rain bands are already starting to move. They're about 50 to 80mi north of where they used to be. In fact the seed catalogs finally adjusted their climate zones on the packages to reflect the new reality.
And they're moving on to areas that are less productive.
Plus we're getting more extreme weather which isn't good for plants either.
My conclusion: we are doomed, not to extinction but to drasticly reduced quality of life due to extemes of climate, first heating that will displace large populations due to flood and fire and cause increased costs in goods and loose of insurability. (Later by the AMOC collapse perhaps) More imigration and reduced food and land resources leading to stresses on democratic institutions and less international cooperation. All favoring greater autocratic governments and more war. Humans will adapt but at a cost to civilization and population. Perhaps this is the "great population reset" needed for the next (22nd) century.
This is based on
1) the fact that climate change first discussed in the late 1980's when atmospheric CO2 in 1990 was 354 ppm. This is now over 420 and rising every year by 1 - 2 ppm. In 1990, CO2 emissions totaled 19.5 GT. This is now over 36 GT. (Pre industrial atmospheric CO2 was 280, and emissions in 1940s was less than 5 GT)
2) during the covid year when basicly the entire world economic activity was drasticly reduced, the Amospheric CO2 continued to rise but at a slightly lower rate. CO2 emissions did fall by 1.9 GT between 2019 and 2020. But atmospheric CO2 continued to rise.
3) Humanity will not tolerate economic slow down of the covid years as a perminant condition.
4) even if we have Zero increase in emissions, because the half life of CO2 is measured in over a century,which means that for at least a generation or two, Climate change will continue.
5) feed back loop-processes progressing toward their feed back point: loss of arctic ice, wild fires (contributing to greenhouse gasses and soot spread by wind to fall on glaciers facilitating melt), and permafrost melting.
This is the MOST intelligent analysis of all the comments made. I agree wholeheartedly with this summary of ideas!
but who is "we"? people in cold areas will enjoy a much less severe environment. more people die from cold than heat. look into the data.
@@quickmythril2398 "We" refers to civiliized humanity as whole. As I said, suvival of the species is likely, just not at the levels of civilization we currently enjoy.
regarding "more people die of..." current causes of death will be less relevant in a climate change future due to 1) increasing heat which whch will displace current cold, 2) delitarious effect on farming with displacement of rain fall areas, drought, flooding and fire, 3) and my biggest concern is diseasse due to either migration of tropical disease into current areas too cold to support them, or from melting permafront releasing a pathogen for which current immune systems are not prepared (especially fungus or virus).
@@granitfog what??? "current causes of death will be less relevant in a climate change future due to increasing heat which whch will displace current cold" ... uhh if there are deaths due to cold, and the cold is displaced, that means less deaths from cold. how is that not relevant?
Population is set to fall dramatically anyway because of much lower birth rates.
This channel is so cool. Very assessible, easy to understand, and i feel like they make sure info is accurate.
If the AMOC collapses it is going to cool the planet? But that isn't good. As it seems only certain regions will experience shifts to a much colder climate. While other areas become hotter and dryer? Am I understand that correctly?
Net zero emissions isn't going to happen. Fossil fuels are too heavily relied on. Even green energy is powered by fossil fuels for energy, manufacturing and delivering.
We need a substitute for oil and we need it fast. One that is organic and has limited emissions.
The AMOC is a major current that transfers Heat from the Tropics to the Polar Regions, which helps keep the Global Climate stable.
All the alternatives exist now, the Infrastructure just doesn’t exist yet so it’s not practical. We need State Intervention and we needed it decades ago
You do realize that fossils fuels ARE organic right?
Well we certainly won’t get any help for this problem from the new guy.
Without the current transfering heat, the bigger difference in temperature will cause even more common and catastrophic hurricanes.
Or at least I think so, climate is complex.
@@Mr.MasterOfTheMonsters I think, as a person from southern india , ground water depletion with fractured ocean current means , effectively no more sense of winter from now about 20 years after in any sensible capacity.

The New England and Mid Atlantic Coasts have been seeing signs of disruption in phytoplankton and this is directly related to the strengthening of the Labrador Current which has been bringer cooler than normal waters down the continental shelf. Ice melt from Greenland’s ice sheet is driving huge changes in the marine environment.
I live right in the middle of the Labrador current. Ice bergs have been floating by for tens of thousands of years. Bergs were written about when the Vikings were in North America. What was the cause of the Greenland ice shelf melt then?
@ I’m on 64 years old so I don’t know how it was 10,000 years ago but I’m positive that you are a world renowned expert in this, so you tell us sandpaper bc I’m not rough enough.
@ it is obvious, if it was melting I would believe that the temperatures were above freezing. 😉
@@Upinthegarden Bergs come from glaciers/ice sheets reaching the coast, so more snow/less melting in the past would have made thicker ice sheets/more bergs. No melting then.
So 2 mile thick ice sheets melting between 15-12k years ago releasing enough melt water to raise global sea levels by 400' didn't cause the AMOC to stop but the current melting in ice sheets with indistinguishable sea level rise is causing it to stop. That is much like the melting permafrost consisting of preserved plant matter being a net carbon emitter rather than a net carbon sink despite the conditions being present that caused the plant matter to be deposited there in the first place providing the source of the carbon emissions now.
Climastrology is cognitive dissonance, all the way down.
No one is talking about how devastating global cooling would be... another ice age would be catastrophic
Fortunately, transitions to glacial periods take tens of thousands of years
So.... I just want to get this straight. According to the professionals the earth has gone through these cycles without human intervention and human caused emissions over and over again... but somehow it's the human intervention that is causing it this time around?
The earth's climate is controlled by a set of natural variables.
As those natural variables change over long periods of time the earth's climate adjusts accordingly.
The issue today is that man is influencing one of those natural variables, and he exerts that influence via his use of fossil fuels
There are natural cycles. The major ones currently operate on 100,000 year timescales. The last 10,000 years has been remarkably stable, allowing human civilization to develop. But much of the preceding 90,000 years was characterized by major climate instability that would have disrupted any fledgling civilizations. Calculations suggest that our current *stable* climate could persist for another 10,000 years, but this stability is *fragile*. Theory and observation tell us that our climate system is 'twitchy', responding suddenly and unpredictably to perturbations.
Rising global temperatures caused by greenhouse gases represents a major 'kick' to our climate system The physics is simple and clear. Regardless of whether CO2 has previously been a 'driver' of climate change in the past, or an 'enhancer' of climate changes triggered by other things, the 50% increase in CO2 over pre-industrial levels (to levels not seen in over 3,000,000 years) *will* perturb the finely-balanced energy budget of earth's surface. Nobody knows for sure what this warming will trigger, but we know enough to make educated guesses, and there are scenarios - like a slowdown/shutdown of the AMOC - that lead to a world characterized by rapid climate *instability*. Human society (and global ecologies) could adjust to gradual climate changes (centuries to millennia). But instabilities that can occur within years to decades would be nearly impossible to adapt to. The result would be chaos.
Yes
Two things:
1- the earth going through those past cycles took millions of years. The cycle took millions of years of to slowly change BUT we humans are doing it in mere decades. The amount of change we are pushing into our atmosphere and world is off the charts. You can disbelieve or laugh at this but you might see it & finally understand in your lifetime (depending on your age & all that)
2- yep the earth changes, it’s changed before so no big deal right? WRONG !! When this changing happens crops won’t grow where they used to, massive food crops will be wiped out. Now growing seasons are being messed up, every year we hear more stories of “oh darn the Georgia peaches or Florida Oranges had the worst growing season ever because storms were very different than before”. Too much rainfall all of the sudden after weeks of drought lead to a massive reduction in ______ (fill in the blank crop this year). That story repeats again and again.
The planet will go on. But YOU humans will have a hard time when the food can’t be grown as easily, when the food shortages lead to famine, war and chaos.
But hey, you sound like the type of guy that laughs & scoffs at “the professionals”. What do they know. You were so smart in school. You do your own research.
Good luck buddy.
Earth will be fine, humans won’t be
@@EchoDoctrine Uhh there have been 30 glacial-interglacial cycles in the past 2.5 million years alone with many more interstadials in between. From 15-10k years ago the Earth warmed enough to melt major ice sheets in North America and Europe which resulted in 400' of sea level rise - if every inch of ice melted today the resulting sea level rise wouldn't even be half of that.
Global crop production is at an all time high. Satellites and ground observations show a massive greening of the planet as higher latitudes warm and CO2 improves growth.
The only thing you got right is that we ARE laughing - at you and all your simpleton climate cult buddies.
Maybe you’re missing the fact about all the water melting off of Greenland and the north, which is causing this cold blob.
Yes, no one has thought of that before. Wow. You did it. Nobel prize for you . . .
Yes. Greenland melting is exactly one of the causes of AMOC collapse. It disrupts the salinity/density/heat balances that allow the corculations to happen. This is known.
As I understand it from friends who are actual researchers looking at Greenland melt water, the reason the blob isn't predicted in models is that melt water hasn't been fully incorporated into the models. It will be after it's better measured, we hope.

@@leftcoastline Yes, the idea is understood. A quantitative detailed understanding is not yet very advanced, so putting the melt into models that use vastly intricate calculations and iterations can't be done very well yet.
0:37 Afraid people are gonna click off if you explain what that stands for?
the following is more serious than cynical, but there are a few things that have got me thinking:
- If the AMOC keeps collapsing over millions of years due to global warming, without us, then how does us our CO2 materially change the cycle?
- If the heating of the AMOC, thereby causing it's collapse, encourages global cooling, then what is the major concern of us being within an interglacial warming period, which again happens with or without us?
- CO2 being the main input source for plants and green life on the planet is also produced through the natural breaking down of methane. Methane being the major output of biological decay, creates CO2 which is absorbed by plantlife, which create fruits/veg/nuts/pollen, etc, etc....and some of the largest zones for this are monsoon flood zones/flat-lands....is this show insinuating that we need to reduce floodlands used as a significant part of our delicate eco-system by reducing rainfall??
- Is it just me, or does the video really just confirm that the planet is in constant flux, and we (as a race bent on survival at any cost) don't want to face the inevitability of the next pending move in the constantly advancing natural global adjustment and are therefore striving for solutions to fight against nature ?? (that we basically cannot accept that the world is changing regardless of our efforts, and that we, in the delusional belief that our species is eternal, need to fix the planet???)
I was always a bit 'on the fence' when reading how farming is a high carbon industry, when I also realise that vast acreage is destroyed on a regular basis for development of more industrial zones...the same green acreage that would have been absorbing the carbon output from farming.........natural carbon capture plants.
This video about the AMOC , I think, just swung me into the inevitability of our situation, no matter what we do. Our collective output has a micro-fractional impact on the natural order of things, and coupled with the weakening magnetic field (which also causes heating through increased solar radiation) the next stage is coming, and mining heavy metals to create electric cars, flying fruits and vegetables all over the world, and recycling your tinfoil hat wont change a thing.
In the United States, the current war on science is getting worse, and education is also worsening. We have politicized this issue to the point that half of the US population feels it a duty to ignore the issue, even if they believe it is real. So as long as politics drives the conversation, there will never be enough consensus to do something about it in the US. The war on science can't be ignored, or swept under the rug. The war on science will prevent any successful outcome. We have a situation where we can't even ask these questions because politics doesn't allow a consensus.
Lol science is in the dark ages and climastrology is a big part of it. Ironically the brainwashing centers you call education has prevented you from having enough critical thinking skills to see the cult of climastrology for what it is.

i absolutely hate how they always boil it down to *only* carbon emissions. its a disservice to the subject to simplify the complexities of this system to put it down to only a single thing.
follow the money, everything about covid was, this is no different. My problem is just showing 20 years graphes then 150k year graphs to say we are in trouble? A thousand years is a blip on earths timeframe and dont care how good a geologist is but probably couldnt get the past right within 10k years.
@@BrianK-zz4fk And they always have to say May,,Might,,,Could happen... etc... Just so they can say they weren't wrong 20 years from now.
@ No Al Gore won an award saying NYC would be underwater 5 years ago🙄. Why people listen to this is beyond stupid.
"A theory that explains everything explains NOTHING! " I see the carbon fraud continues CO2 is not the problem and never was - ITS PLANT FOOD people!! This fraud is a way for Governments to tax and control the populous it is making some people very rich. This very program stated that 28,000 years ago IT was warmer then now! didn't see a lot of cars back then!!! The world has been colder way longer then it's been warm enjoy it while it lasts because Ice ages are very long and not any fun. The climate is affected by so many things like the Milankovitch cycles ...which includes the shape of Earth's orbit (its eccentricity), the angle that Earth's axis is tilted with respect to Earth's orbital plane (its obliquity), and the direction that Earth's spin axis is pointed (its precession). People have no problem understanding the four seasons but some how don't think the sun has much impact on our climate...REALLY. Fossil fuels are not the problem it's BAD science that is the problem, poor temp gather data, and global weather models that have never worked. WAKE up people the Carbon Fraud needs to end!!!
This literally says over and over that the AMOC collapsed without humans...
YES, exactly. :)
Well, if you're gong to take that tack. The AMOC was probably non-existent once you get more than a few tens of millions of years in the past. Without an Atlantic Ocean, you have no AMOC.
So, it's all good I guess?
@@stainlesssteellemming3885 yes, it's all good. there are major cycles in the earth, sun, and galaxy. humans are a speck of dust compared to all that. to pretend like we could influence it, is like trying to steer the titanic by paddling with a plastic spoon.
Yes but if you turn off your brain and reach the cognitive level of a zombie you too can become a climate cultist.
Canada has Polar Bears at the same latitude as Birmingham, England.
Great report - the key issue is getting people informed. But then what - how do we turn information into action?
I dont think we really can. Most people don't want to change their behavior and that's the only thing that will save us. We can't wait for corporations or governments to do anything. The time for that was 40 years ago. People need to go vegan, reduce their emissions, and stop buying stuff they dont need. The average US Citizen can cut their emissions by nearly 50% with nothing but behavioral changes. As a country we could cut our climate impact by a similar amount without asking politicians to do a thing. These things could happen immediately.
Unfortunately we have the mentality that "China is worse" which just kicks the can down the road. We have conservatives who still refuse to even acknowledge the problem exists. We have therapists telling everyone to go ahead and buy another latte because you had a hard day. The can is constantly being kicked down the road by everyone because accepting that we all have some responsibility is too depressing or too hard. It's sad. We're all responsible everyday we don't do something about it.
It does not matter how many facts you give some people, they will still ignore what is staring them in the face. Just look at the recent U.S. election.
What fact is that, that your IQ is ~ 70?
keep up the good reporting stay safe , well and brave
Saltwater farming in desert coastal areas. Rain retention/reclamation systems in deserts like they are working on in India and parts of Africa. These create green areas which will also work as carbon sinks, and also keep those areas cooler.
Using Celsius and Fahrenheit in the same video and then referring to both as "degrees" is a pretty big fail for a science channel. It can get very confusing for people less educated in the subject. Just stick to C° and the metric system, they're the scientific standard.
If I am getting this correctly, you think that the AMOC is slowing due to global warming because of CO2 emissions, but once it slows or stops, the earth will begin the glacial cycle that is going to happen anyway and the earth will get dramatically cooler, affecting rainfall, which is going to come in areas previously not getting much creating more methane. If this is true, wouldn't this also prevent methane now rising fron areas where permafrost is thawing? Wouldn't cooler northern European temps also cause the Greenland ice sheet to reglaciate instead of melting? That sounds alot like a loop of warm and cool periods. One thing is obvious in this video, and that is the fact that we are nearing the end of a warming period that is a natural cycle and we still are several degrees temperature below the last warming cycle. I think the Milankavitch cycles are the most dominant factor while you never mentioned that at all, as if it doesn't exist.I suspect that the AMOC will cycle more rapidly if what your evidence provides is correct but will eventually reach a point where the Milankovitch cycles make it a permanent cooling until the next interglacial rather than expediting the next glacial period of the current ice age. Trust me, you do not want to see another deep freezing glacial period where the ice is many miles thick and most of earth is covered in ice, but history shows that it will happen. Humanity needs to plan for this with every modern technological advantage we can muster. I also do not trust any science that does not include the amount of CO2 produced by breathing animals such as 8 BILLION humans. I need to see and hear from scientists who account for all factors rather than just CO2 and wild predictions that exclude all other factors. For example, If CO2 that represents about .04% of the current atmosphere is such a driving factor, what caused the melting of the glaciers before mankind even existed? Where did such an enormous amount of CO2 come from to cause warming enough to cause the current interglacial warm period? The answer is there, but scientists affiliated with the IPCC are not interested in anything that could stop cash flow to them and their never ending studies on CO2. They really should get to the bottom of what created all warming and cooling periods.
"I think the Milankovitch cycles are the most dominant factor". I agree. Plus, the ice core data shows that when the temperature drops, due to the Milankovitch cycles, the ocean dramatically absorbs much of the CO2 in the atmosphere. By destroying the entire fossil fuel industry, our ability to put some CO2 back to keep the planet warm is gone.
Don't try to apply any logic to their dogma or they will call you a denier - ironically a religious term.
It is colapsing, the coral reefs are dead bc the sea is 6*C warmer than 15 yrs ago, the sargasso extends almost all over the atlantic during the summer....There is NO wind.
Drastic changes about to happen, perhaps 2030(?)

Coral reefs in the tropics are doing better than they ever have before - keep up with the research
The only warming of 6 degrees is that between your ears - a major meltdown seems to be occurring.
This presenter is really very very good. She is so clear and so precise! ❤
Just one thing, you keep mentioning fahrenheit, a uniquely American thing... why not use a measuring method that is used as standard by the scientific community globally, as well as about 99% of the planet... celsius?
Because Americans think the world centres around them - but only the ones who realise there is a world outside the USA.
Perhaps because the US has one of the highest concentration of climate deniers on the planet? In which case, you want to frame the data in terms they are familiar with.
Because Fahrenheit is more precise, scaled for normal temperature variation at the planet surface, invented just for that purpose, by the guy that invented the thermometer.
She was real cute until she opened her mouth and started talking about climate change
You might want to ask Mr. Orange what the AMOC is and how his proposal to drill for more oil, coal and gas might tip the AMOC. Then again, corporations will just keep on going, as long as there is profit to be made. So, start preparing your survival communities today because its gonna be a long, long,long cold period.
I think politicians control the weather, I am really smart
the doubt about amoc collapse will not survive the 2050's. the impotent political machine of the old world will not avoid this catastrophe of our own making. the old system is and must collapse so future generation can build with lessons learned. who can we blame? it is our own persistent ignorance that is the cause 🙂
extreme climate alarming. Climate is an issue but not in the top 5 for humanity. Wind and solar subsidies bleed resources for a non-solution. the hope is that humans will nor manage to pull-off large scale climate meddling and natural fluctuations will take over from there.
In my book political isms should not be a part of the task to get our world transitioned to an emission free energy production and usage. No matter if anyone are on the left, centre or right political spectrum, they need a planet with clean air to breathe, waters that are healthy and filled with life and an unpolluted landmass to live on.
Glaciology now scientifically have documented our atmospheric carbon content, YEAR BY YEAR 1,1 million year back, thus we know the conditions that paved the way for our creation. It is in itself remarkable that we can do that, considering it´s only 65.000 years since we left the African continent for the first time. This insight have told us, that there have been cyclic slow climate changes happening before but that these have not really affected the atmospheric carbon content much. However 3 times in the 1,1 million years, large widespread global volcanic eruptions have made sudden changes in our atmospheric carbon content with up to 30 PPM over the otherwise relative stable 220 PPM the planet´s regulating systems prefer and try to seek back to, and EACH time it have triggered abrupt climate change. Since around 1880 and until today we humans have caused the atmospheric carbon content to go up with over 200 PPM!
Our atmospheric carbon content do not care what corrupt people agree behind closed doors at shady meetings, it´s simply responding to the massive amount of greenhouse gasses we spew out.
In this very matter we all are in same boat. I am a strong believer in democracy. The problem I see in to many nations that call themselves democracies, seem to be that the fossil fuel industry have managed to corrupt politics and those operating in politics, in ways that have short circuited democracy, helped by a media landscape supporting the lies and dis and mis-information. I do not think it are a coincidence that the 4 nations where Murdoch media have significant market shares, Australia, USA, Canada, UK also are the large nations with highest greenhouse gas emissions per capita. What we globally should be doing RIGHT NOW is to be in the middle of an "Apollo program" effort to make a fast transition to emission free energy production and usage, simply driven by our understanding of the urgency our current situation dictate. It would, on top, create massive growth and prosperity around the world but do so sustainably and provide the foundation for a circular economy. If we do not urgently get our planets temperature down, we have entered the beginning of the end of a world remotely recognisable, to what we know, will allow humans, the species we share the planet with, the fauna in air, on land and in our waters to exist. Mars lost it´s atmosphere and in the end, the same can happen here, although I suspect we will be long gone by self eradication before. The future that have begun will come with massive random disruptions caused by extreme weather and it will randomly take away peoples livelyhood and traditional living conditions.
WE NOW have ALL the knowledge and technology needed to make a complete and fast transition to an emission free energy production and usage. Our grandparents can be excused since they did not know the consequences of their actions. Our parents should be ashamed for not acting in time but WE have full insight and the solutions and thus we truly now act as the ultimate morons. If there will be any left to write history books we rightfully will be judged harshed. Name one other mammal that knowingly and deliberately destroy the very habitat that provide the foundation for it´s existence. Our house IS on fire and currently the consensus seem to be that massively pouring fossil fuels on the fire miraculously will make the fire go away. As normal human beings, WE MUST NOW INSIST politicians, no matter from what spectrum, are able to present a plan for making own nation carbon neutral FAST!
Sadly our corrupt politicians are in the thrall of the fossil fuel industry, and that's why we're in the mess we're in.
10:38 i say lets go for it... we don't deserve this planet.
yes, thats right
For the record, your pickups don’t hurt the environment as much as the 1k nuclear weapons governments have tested this century!!
The sad part is the fossil fuel industries consider the destruction of the planet a cost of doing business.....
I guess you don't use them
The world is already changing dramatically. This year had so many unnatural disasters. Rainfalls killing thousands in the Sahara desert, Spain, Dubai etc‼️
Floods have never happened in the past
The floods in Dubai were because of manmade cloud seeding and in Spain was due to a canal being diverted and even if that wasn't true flooding has always happened anyway...
The winter is coming…
I’m from the UK and what terrifies me is that after 10 or so years of looking into renewable energy sources and finally seeing the light on moving away from fossil fuels some countries are starting to get governments that are climate change denier’s and want to reintroduce our reliance upon fossil fuels. However there are also some countries that are more than happy to buy Oil, Gas and poor quality coal from countries that are under restrictions and are exporting to countries like China, India and some Eastern European countries which are getting these fuels at a discounted price.
Wa also have countries that have a vested interest in selling fossil fuels to stay rich and relevant energy providers. For example Russia is currently producing some of the dirtiest coal in the world and exporting it to whoever is willing to buy it at a huge cost saving, however the countries that are buying it are using it to produce cheap electricity for their expanding energy requirements for their expanding economies. Until the world is willing to invest in renewable energy we are just going to destroy our environment and by then it will be too late.
Heck even the UK no longer uses coal to produce electricity.
There is no "too late" in this discussion my friend.
Look, it is UNDOUBTEDLY true to say that mankind has INADVERTENLY geo-engineered himself into a corner with his use of fossil fuels, but it is also true to say that mankind can PURPOSEFULLY geo-engineer himself out of that corner as well.
Will the road be a little bumpy?
Sure, but man made climate change is NOT going to be the end of the world.
We have added a lot of carbon into the carbon cycle, and yes that is warming the planet some, but at the same time we can also work to remove that carbon from the carbon cycle which will in turn cool the climate back down.
Relax, things will be fine.
Climate Alarms must be amplified, not muted.
Climate alarmist are always right
Atlantic Meridional Overturning Circulation (AMOC)
Thank you!! I could not find where she said what the acronym was.
It's amazing how people figured out how to learn such things.
“According to climate models this gigantic blob the size of a continent shouldn’t be there” maybe the climate model is very very wrong then
I think humans don't understand the complexity of the earth's climate. We have such a limited scope of understanding of the earth's climatic history that we are only making speculative conjecture based on only a small historical window of comparison. It can't be denied however, that humans have a larger negative impact on the climate with more than just c02 emissions, but deforestation, general chemical pollution, and habitat destruction. Those are the major issues causing climate change. Me not driving my car isn't going to stop climate change, implementing strick environmental regulations on companies and governments is the answer. Not allowing the creation of toxic chemicals and not allowing widespread habitat destruction is the answer.
Every time you burn just one gallon of gas in your car/truck, you add 20 pounds of CO2 to the atmosphere where it will remain for centuries. Every tankful of gas adds 200-1000 pounds of CO2 to the atmosphere, so yes, us driving and heating our houses with fossil fuels and eating meat (especially beef) are all part of what is causing the climate crisis.
1:40 states AMOC brings waters from the gulf to the N. Atlantic.
Not too certain how the current passing from the carribean side of the Yucatan peninsula to the Atlantic side of Florida would be considered ocean waters from the “gulf”. Am I missing something?
I highly respect PBS journalism and this Terra series is great because it will reach the key audiences that may now have attention issues on a regular hour program. Thanks PBS
That cold spot near Iceland explains why they were significantly colder last winter. Reykjavik never got that cold when I lived there from 1986 to 1988.
I find it odd that we are being shown how all these patterns have occured naturally many times before, but then being told that this time it's our fault and we can do something to change it.🤔
the graph at 10:31 looks really scary. That abrupt change at the end is so extreme and unnatural that the conclusion is that the AMOC collapse will be not only inevitable, but very fast and even more extreme...
The sky is falling
Even without a full collapse, the changes can affect us drastically.
It’s like when your house is on fire and instead of putting the fire out we are discussing if the fire will destroy the house. Pure madness, we need systemic change.
Alarmist think a little warming is the end of the world
@kmoses582 are you delusional? We are living in a mass extinction while mankind is destroying entire eco systems all in the name of profit.
"'Did you ever see such a winter as this?' asked one sufferer of another. 'Yes, last summer,' was the answer." James Quin
Unfortunately we're likely to reach 3 degrees before 2050 or even before, not 2100. We've already passed 1.5 degrees this year and we're accelerating drastically...
This year alone we jumped over 0.1 degree. more than all the 80s combined.
Overall great videos. Balanced and not sensationalist
