Thank you! This is going to require a global human effort to save our asses. Unfortunately I'm not so optimistic that it'll happen in time. Humans tend to be ill believe it when I see it type and Unfortunately even though there seeing it it's easier to mock us and call us alarmist or conspiracy theorists than it is to face reality. Everyone seems to be trapped in this bubble and they can't see past it. I'm deeply troubled by it sighs... we all are..

“If” it has happened before, it isn’t due to “ human activities “ ( even though they “may” accelerate the process); it’s obvious that there isn’t nothing we can do to stop it! Nature is the Master.
I wanted to take a moment to express my sincere appreciation for your video. It was not only informative but also incredibly engaging. Your passion for the subject matter truly shines through, and the way you present information is both entertaining and easy to understand.
This triggered a memory of a snot nosed kid version of myself raising my hand to ask one of my favorite primary school science teachers; is it possible that ocean currents and temperatures could affect the flow of magma beneath the ocean floor like they do with the weather and winds, causing earthquakes and volcanic eruptions? My amazing science teacher looked like she was getting teary eyed. Looking back, it probably made her day.
I have lived in Alaska since 1977. Since 2008, we have lost much of the cold winter season. no longer did the Kenai Peninsula fall below -30 F in the winter. Average winter temps ate 24-35 degrees. Our summer temps have risen to the mid 70's from a mid 50 degree average. Worst of all, we have experienced massive dieoff of plants and animals. Most of our spruce trees have died due to the spruce beetle not being killed off in the winter months. First we lost starfish in the ocean. Then we had massive dieoff of birds and seals that fed on previous plentiful stocks of baitfish that are no longer present. In the last 5 years, our stocks of king salmon and chum salmon have crashed so bad that there are no longer catches of sport-caught salmon allowed even if all you want to do is catch and release. Commercial fishing using set nets have been closed due to possible catching a king salmon. Also crashing are the once prolific stocks of king crab and snow crab. There is a culprit here and it is the burning of fossil fuels. Burning of coal, oil and gas produces sulphuric acid. When sulphuric acid fall into the ocean, the water gets more acidic (acid rain) and that kills the base of our food chain, zooplankton. Since 1980, the presence of zooplankton in the North Pacific Ocean has decreased by 90+ percent. This also explains why the size of the king salmon that do return to spawn are less than 20lbs a piece. in 1990, the average size of kings returning to the Kenai River averaged 54-66 lbs with about 1/3 of the salmon exceeding 65 lbs with catches of 90+ pound fish occurring weekly.. Face the reality that the Pacific Ocean is dying. The Federal Court closed the last troll fishery for King Salmon in the Pacific Ocean to stop the dieoff of about 72 Orca whales that barely survive between Canada and Washington.
These facts you mention might still be caused by the natural cycle that stops the AMOC, since the AMOC has stopped many times before in the history of our planet. I do not deny that our polution has global consequences. But we have to know wheather the due stopping of the AMOC is solely caused by antropogenetic warming or that the natural cycle is the main mechanism. In the latter case there is no preventing the collaps of the AMOC and hence the next ice age.
As posted by someone else..... The Arctic Ocean is warming up, icebergs are growing scarcer and in some places the seals are finding the water too hot according to a report to the Commerce Department yesterday from the Consulate at Bergen, Norway. Reports from fishermen, seal hunters and explorers all point to a radical change in climate conditions and hitherto unheard of temperatures in the Arctic zone. Exploration expeditions report that scarcely any ice has been met as far north as 81 degrees 29 minutes. Soundings to a depth of 3,100 meters showed the gulf stream still very warm. Great masses of ice have been replaced by moraines of earth and stones, the report continued, while at many points well known glaciers have entirely disappeared. Very few seals and no white fish are found in the eastern Arctic, while vast shoals of herring and smelts which have never before ventured so far north, are being encountered in the old seal fishing grounds. Within a few years it is predicted that due to the ice melt the sea will rise and make most coast cities uninhabitable………I forgot to mention that this report was from November 2 , 1922, as reported by the AP and published in The Washington Post 100 years ago. The climate has been changing for 4,500,000,000 years, you cannot fathom that number and I bet the aholes destroying art can't even tell you what a billion is. BTW I am typing underwater in NYC since we have been under water for 23 years now.
@@Acccountable You know you're facing a professional or voluntary shill when their argument is 1 - hard to verify, 2 - hinges on a single point, 3 - emulates "justified outrage", 4 - ignores literal thousands of papers arguing the opposite.
@@Acccountable "As posted on Facebook groups of climate skeptic..." FIFY. Climate has changed overtime but there's enough studies and papers to prove humans are now interfering the natural balance of climate. As far as 4.5 billion years of climate change, that's the age of the planet. Doesn't mean it was habitable the whole time. 800 million years ago was the first multicellular life found, and even at that period I bet no human could live. If your best shot is to cite a 100 years old newspaper article where your same "someone else" added the last sentence just for the sake of destroying it... Tinfoil hat ahoy, my dude!
A good video. Whether one believes in this doom scenario depends upon how much faith one has in scientific institutions. My experience working on the Great Barrier Reef since 1984 has left me like Christian who has lost his faith. I therefore have no idea what to think about this AMOC collapse phenomenon despite being a physical oceanographer. The doom stories about the Great Barrier Reef started in the 1960s and have been going on ever since. There are reports every month or so about how bad the coral is . And yet the latest statistics from the Australian Institute of Marine Science reveal it has never had more coral than this year. This despite 4 "devastating" bleaching events in just the last 6 years. The latest statistics demonstrate that many science institutions got it totally wrong about the reef. The institutions have been overtaken by groupthink. I have been calling for much better quality assurance in science institutions, something that got me fired in 2018. So, brilliant video, but there is now far too much evidence that much of the peer reviewed literature is greatly flawed. Until something is done about that, I remain a scientist to the core but a lost soul about the science institutions. Peter Ridd. ps, why not contact me about a video on the Great Barrier Reef
I recently found out about glacier girl, a ww2 plane in Greenland that was buried under 250ft of snow in just 50 years. It’s hard to reconcile this with record melting that we hear about constantly.
www.aims.gov.au/information-centre/news-and-stories/great-barrier-reef-not-fine-and-nor-it-dying-truth-inbetween And increased snowfall isn't necessarily counter-indicative of rising temperatures. In fact, increased moisture in cold climes could be indicative of warming.
Agreed. These models are speculative at best and passed off as if they are fact. We don't have the understanding or model resolution and processing power to drive it to get to the accuracy needed for the claims made. Sure it is something of concern and the models might be partly correct, but we don't know. History has shown again and again all these predictions to be wrong. The world has a large buffering capacity that addresses most of the sky is falling issues.
The issue is humans stubborn resistance to thinking beyond their own life span. Add this to little to no knowledge of the past. What we do know is basic physics of greenhouse gases. We have pretty good grasp of how much we're adding to our shared atmosphere, oceans. We also know there's no Oil Fairy refilling the holes with hydrocarbons. That the easy fossil fuel finds are nearly non existent. That these fossil fuels provide overwhelming majority of our fertilizer needs, feed stock chemicals for thousands of products. That a spike in their usage since industrial revolution has added 7 billion new humans with 80 million net new precious humans joining us annually. Business uses the idea of leading indicators and lagging indicators to guesstimate the health of their businesses. Problem with leading indicators is you generally don't recognize them until they pass by. For me this is enough to act on! Don't need 'six sigma certainty' or an impending collision with a civilization ending meteor. Thanks for video!
I can't see how you've got fired for calling for better quality assurances. At the very least you are omitting things here and biases opinion against institutions, leading the readers to agree with your statements by defamation, the readers here dont have access to either your firing case and the scientific publishing you mentioned. That being said, pay for publishing and pay for reading scientific articles make for bad information flow. Even worse, only-positive-results publishing eschews scientific advancement, science should also note, pier-reviewed, what doesn't work, but there are no funds for that. Worst, and related to your post, lack of revision for why certain predictions / published papers didn't pan out don't sell, thus we don't get funds for them.
The problem is most of the climate changes you’re describing we are unprepared to deal with. The solutions involve massive starvation and collapse of all industrialized economies as we know them.
they're gonna happen anyway, it just won't be volitional. But the effects of climate change will persiste even after our modern industrial society is gone
On a purely intuitive understanding I believe I will experience the AMOC stop flowing. A visitor had come to the farmhouse and he was speaking on this. I was sleeping upstairs and remember sitting up like a jack in the box hearing his declaration. Just knew it was something that had relevance.
Yes, it will happen within the next 10-20 years or so, the Beaufort gyre is long overdue for spilling over. ruclips.net/p/PLHSoxioQtwZcqdt3LK6d66tMreI4gqIC-
It would have been useful to have included some information/theories on how and why AMOC has collapsed multiple times over the last few millennia. Thanks for the video.
Exactly my thought. If it has collapsed multiple times, is this not just a cyclical event? Is green house gas the cause or something else? When I was a kid the climate science was predicting another ice age by now.
That has always frightened me upon learning about this in the late 80’s in my geo-studies. The other big scare was learning about how much methane, and the potential of release with more warming of the arctic tundra.
We need the aliens technology and we need them to tell us what we need to do we need their help, maybe this is why they're trying to force disclosure. I don't know but I do know that it's all true what they're saying about the aliens and the secret space program. Because of 1969 when I was only eleven years old and living in Roseville California I would see them anti-gravity craft come up every night on maneuvers look like they were training for something they were very organized I wasn't the only one who saw them in my neighborhood they were very high up though like satellites but it was definitely anti-gravity craft that could travel several thousand miles per hour and as I watched them for four whole years and they had two nights off per week they increased from thirty-five to forty up at the same time I kid you not I'm dead serious. I have never forgotten what I saw those many years ago then my father took a transfer to Houston and I have never seen any in Houston but I have heard others say they have seen them seeing is believing.
@@retiefgregorovich810 well, I also remember that prediction but the methane makes co2 look like a child’s Chemical playset. Regardless, we’re all in for a ride and consequences. If what you see as normal in your 50-60+ years, then you’re not paying attention. Ice age was a planetary alignment which should have snapped us back into cooling. That worked in a pre-agricultural world. It’s no longer the rule with all the driving inputs. I know, I know….yammer, yammer dooms day.
Thanks for reminding us. Sadly though, we (people knowing and caring about global warming) have known about this for about 30 years. I doubt the public will ever take any interest in the issue until the stream collapses. And people playing down the problems we face are still VERY prominent in the media.
Unfortunately us humans have advanced so rapidly that we convinced ourselves that our silly imagined human world is all there is and everything outside of it is just there for our use. Sure the weeds growing through cracks in the pavement always give me hope. While "intelligent" life may possibly be a short term self destructive phenomenon, life in all it's splendor has been through hellish periods before and is very capable of coming back from cataclysmic events.
Indeed we have known about this for the last 30 years. It's the old chestnut that won't go away. Helped of course by "The Day After Tomorrow" movie. I was in a tech support job by then, and all my fellow nerds were quizzing me on the movie, knowing my environmental background. The number of times I had to explain that, yes, what was being illustrated was absolutely possible, but no, not in the time span depicted by the movie. And further details thereafter. If I had dined out on every explanation I'd have ended up like Mr Creosote. Excellent informative video Dave, as always. I love those dropped articles. Do you do the graphics? I may have asked this one before.
@@martincrotty haven't given up hope that my quiet corner of this world will be mostly spared from cataclysm. That being said I bought a cabin in the woods and have that stocked and ready to sustain me for a year or so (without nuclear fallout so let's hope Russia simmers down 😅)
Civilization collapse usually happened when a society is too rigid to adapt, for instance mesopotamia wouldn't move their great capital when the region dried up of water, so eventually they became sand people and eventually died out (if I remember correctly). Now though, the hurdle to geographic shuffling to better climes is because everywhere is occupied already, most people can't afford to simply reshuffle. Personally, I had nothing to my name so moved with ease to somewhere I can live better, although it would be harder now as I've children and a home, but at least I'm living less dependent on rigid systems than the ones I used to struggle in (cities and then high cost of living areas). When the flood comes, now im part of a community that won't/can't lock me out of the arks. I wouldn't have children now if I hadn't moved far when it was a terrifying prospect full of risks, but taking the plunge seems to have paid off. Humans are adaptable, but other species are not and all need a spot in our neighborhood arks. Let's do what we can for our wild friends, whether that's leaving them space in the garden to nest, supporting conservation groups, switching to more responsible energies, etc. That awareness felt fruitless when I had nowhere to call my own, so I moved and it is better now. 🌝
You seem to have achieved my dream. I’m quickly approaching circumstances that would allow a potential relocation to somewhere else in the world to live out my life, in a manner that you describe. Would you please offer some potential destinations for me to research and consider (?) Thank you. May you and your family have a happy, healthy and peaceful new year in 2023.
Sumer became assumed by Akads and then this group known as Assyrians and Babylonians put death nails in it, and to salt the earth the Iranic peoples begin filtering in in mass.
One reason I follow this channel is that you present this knowledge in a simple and easily understandable format for the masses. It is one thing to talk about climate change and other studies, but half the time they are presented with enough jargon that it just goes flying over everyone's heads.
Thank you for your posts! Slightly disturbed that I am getting more subtle climate denial dressed as science popping up in my feeds and I've been almost tricked. Worrying that there really are no politicians with the scientific background to actually address this fundamental existential predicament. Experts are gone and financiers have taken over the controls. It's going to get very ugly.
@@richardsmith579 that's nonsense. Would you accept money to destroy the planet on which you and your family live? Then why do you assume "the experts" would? The financiers have no need to pay experts, because nobody listens to the experts. They instead own the media and modulate the presentation of facts in such a way, that public remains aligned with their profit goals.
Subtle climate denial? or just real unbiased un-politicised science, the simple truth is non of them or us really know, and we humans have no control over the universe. Live well now and the future will take care of itself.
If you post something that builds a human induced Co2 climate crisis you will get a lot of well read people who understand that this is a WEF agenda. Many also understand that the climate has always changed and will continue to do so whether we have a personal carbon credit system or not. Also scientists who study solar activity had predicted the coming 2030 freeze back in 2015 however they have now been silenced. Maybe you need to do some research yourself I’d start with the WEF personal blockchain linked carbon credit system.
What do you mean "Climate denial?" No one denies climate exists and changes. Just name climate prediction climatologists have gotten correct. Islands like the Maldives were predicted to have been flooded by now, they've risen by several meters. Our planet has benafitted from more co2. Our biggest danger is pollution, plastic in the ocean. What have you got to say about climatologists adjusting some of the records to make warming appear true, or worse than it is? I can provide graphs by NOAA and the IPCC that have removed the medieval warming period and the 1030s warming.
So the delivery has become much more casual and realistic. I've not heard him before but I can tell you he could also sound authentic if instead of reading from a script at a rate of knots, he were to speak from the heart at an intelligible speed which gave the listener (there's nothing to view) those vital moments for the meaningful assimilation of such important information. Is it possible to play this video at a slower speed?

Thanks for a fascinating video with a clear explanation. I had read of the collapse of the AMOC in an article published about 20 years ago. It seemed to postulate that the result of the collapse would not be a planet overheating but that the event could usher in a new mini-ice age due to the resulting shift in ocean currents. Regardless, I have felt that what we are faced with globally is (and has been) something we as humans cannot really abort or effect even if we coordinated globally to cut our greenhouse gas emissions, etc. The best we can do is prepare for what is moving upon us in the form of such things as much more radical weather (i.e. hurricanes, tornados) as well as devastating sea level increases which will leave low lying areas such as Florida and most coastlines radically changed. This type of preparation the human race could actually do with success even at this late hour. But we fritter away invaluable time conducting useless climate control gatherings of heads of state and sign useless, unenforceable treaties and, in the end , remain in as bad a position or worse. Our governments and global organizations are the perfect example of the small orchestral violins playing on the deck of the Titanic as the ship slips below the waves. The best efforts that can achieve some sort of security is what can now be done on the personal individual scale. Do not rely on your government to save the day. They are too busy performing the political calculus to really produce a safe , secure outcome for anyone other than themselves.
Though you have expressed your ideas very well, it would be good to remember that Floridians (highest spot: 345 ft.) can move to Georgia (plenty of land over 1,000 ft. and highest spot: 4,500 ft.) (Might do well to stay away from Alabama, though; Edgar Cayce predicted southern Alabama would sink.)😏 Holland has some land 6 meters below sea level (That's minus 20 ft.) and yet they have been able to cope and even to drive back the sea for hundreds of years, even BEFORE they had electric pumps. In the German language one says, "Es wird nicht so heiss gegessen als gekocht!" ("You don't EAT the soup as hot as you COOK it!" meaning: There are LOTS of theories going round (believe it or not, making us hotter AND colder) and all from good scientists, but not ONE of them knows all the details of what it's going to be like in even forty years... a few things, maybe; everything: NO WAY! Fogedabodit!😉
“Do not rely on your government to save the day.” This is why I do not trust Republicans on global warming. This is your mantra and you derive conclusions from it rather than from what you see. You know well that the only institution even remotely powerful enough to stop global warming is government which you are ideologically opposed to. It is in your interest therefore to deny anthropogenic global warming, so that government will not expand. I warn you that this foolish and myopic viewpoint will come to haunt the Republican Party, particularly in places like Florida. I do not believe in anthropogenic global warming because scientists tell me to. I believe it because it aligns with the evidence that I see and logically follows from things that science taught before we realized anything about global warming. In the past, like the during the age of the dinosaurs, the earth was significantly warmer as a result of higher CO2 levels. That CO2 was sequestered into the crust and the earth cooled, so much so that our era, the Cenozoic, is far colder than that in which the dinosaurs lived. Indeed were it not for volcanism plants would eventually freeze the earth solid. We have spent one and a half centuries releasing the Carbon that warmed the earth in previous eras. Therefore, we should expect the earth’s climate to resemble that of previous eras on account of our activity. This is an entirely logical assumption and we have photographic evidence of it happening. Of course, the story is slightly more complicated in its details, though not in it’s conclusion. Usually volcanism is slightly more effective than sequestration, for most of the past half a billion years the earth has been free of ice caps. Indeed it’s not as if volcanism has been absent from our present Cenozoic era, in fact it’s been relatively steady. Both volcanic carbon emissions and carbon sequestration by plants have both been relatively steady. So why did it change? Well there is another reason why the earth cooled that had nothing to do with the continuous sequestration of carbon. At the beginning of the Oligocene Antarctica froze solid because of the Antarctic circumpolar current, that and the formation of the isthmus of Panama are the real reason why the Cenozoic period has been so cold. Our oceans will “fight” against global warming so to speak because its circulatory system has feedback mechanisms that favor a colder climate rather than a warmer one. But those mechanisms mitigate normal fluctuations in the warmer direction, and this not a “normal” fluctuation. The fossil fuels we burn are added on top of the steady volcanic emissions, and that is happening on a scale that’s orders of magnitude faster than plants could possibly sequester it. The effect that this has is not business as usual; it is much more akin to the eruption of a large igneous province, like the flood basalts of old. Except this time there are no flood basalts, we are dumping the CO2 into the atmosphere. If we keep dumping CO2 into the atmosphere the feedback mechanisms keeping the Cenozoic “ice house” climate in place will be overwhelmed, and the climate will go back to what it was like during the age of the dinosaurs. Bite the bullet, you need not do anything unconstitutional. Even under a strict originalist interpretation, the Tax and Spending Clause combined with the power to raise tariffs gives Congress all the power it needs to fix this problem. The longer you wait the more extremists there will be demanding more “radical” solutions.
So, the experts don't come to the same conclusions?? So much for climate experts! Let's work on things we CAN make a dent in (eliminate waste, war, etc.).
I agree , weve globally unanimously come to the same basic conclusion that something is definitely happening. 🤔 most go to the denial. . To prepare and stay aware .

@@galoalbertosantanaruiz5737 And arctic warming is easily explained by increased weakening of the global magnetic circuit and pole shift. and the resulting influx of solar and cosmic plasma radiation and their interaction with the earth's atmospheric and solid electric circuits.

The Thermohaline circulation might collapse, but it won't stay that way for long. The waters around the equatorial line would become excessively hot and the water around the poles would frozen, increasing salinity of the water near the poles and then moving south towards the equatorial line, thus, restarting the circulation. However, the direction of the circulation might be different.
@@lrvogt1257 Yup, "not long" could easily be a decade (or more) before the salinity disparity is great enough to kickstart the circulation again. Once halted, that is a lot of water to get moving again.
Happy to be proved wrong but I think the system wouldn't be a simple jump in climate - it would tend to oscillate for a thousand years or so before stabilising in a new equilibrium. If AMOC shuts down then the North Atlantic gets colder. This reduces ice melt from Greenland which tends to allow AMOC to start up again. Once started Greenland melts again which kills off AMOC once more. I did see a graph many years ago showing this pattern at the end of the last ice-age, although I couldn't find that graph again. The change in temperate was dramatic - complete step change. After a few years there was a step change back to the original temperature for another few years, then repeat. This oscillation in climate would effectively kill agriculture - it is very hard to grow stuff when you've no idea what climate you are in.
There are multiple studies of paleoclimate changes which were massive temp changes that occurred within a few decades or less. Some of the oscillations are very extreme and rapid according to some studies.
@@dannybrashear5857 Yes. Oceans currents are well known phenomenon and their cycles are 60-65 years from warm to warm ( or cold to cold ). Now they are turning to cold phase again. North Atlantic Oscillation (NAO) and Arctic Oscillation (AO) are already in cold phase . Last time when this happened we were under ice-age threat which suddenly changed to AGW when they turn to warm phase 1978. Now it´s time to panic coming ice-age again (AGC - maybe?). Climate science use these normal changes as possibility to make money. All studies (there were plenty) which proved this oscillation are hidden somewhere because they don´t support climate change (AGW) script.
You are a very much needed eco warrior, sir, I salute you. Thanks to people like you, we can no longer use ignorance as an excuse for what our behavior is doing to the planet. Your children and grandchildren will be very proud of you (if we ever pull out of this).
I built models for govt and corps for many years. even with advanced computers it is really difficult to take into account inter-actions of all the systems: eg. sea water termp, salinity, and atmospheric circulation, east/west, south/north. with the wild card of eight or nine tipping points that can pop off randomly it all gets impossible to predict with a high degree of certainty. this is why global warming pace consistently surprises scientists. that aside, all of us need to take climate action to heart. not sure how anyone can prep to survive it. but perhaps we can delay the inevitable.
Your point about the models is the key, in my view. There are many variables and indeed many interdependent systems that make the accurate modelling of climate change extremely challenging. Ocean circulation is just one of these systems. To make matters worse, the collections of systems itself is not static. For example, consider the effect of more CO2 on vegetation. We have already seen a 15% increase in planetary "greening" owing to rising CO2 levels. We could ask, what influence does this "greening" have on ocean circulation and vice versa?
Excellent presentation, well documented and presented in a way that is easy for the ordinary folks like me to understand. Thank you very much . Expect more such videos.
What caused the AMOC collapses that happened before man was a factor? Are these collapses the actual onset of ice ages? Do not understand the term "equilibrium" as it applies to Ice Ages and Warm Interstial Periods. Change seems to be the order of the day re temperature.
I'm amazed you managed to keep a straight face when suggesting all countries come together to Actually create a real plan of action and follow it.. I kept waiting for a "Yeah right" or something far less Kiwi oriented..
That's the main thing: we know that all the world should collaborate to slow down or reduce the climate change trends but, at the same time, we also feel that tha's an unrealistic expectation!
High quality production and well researched! Thanks for the time you put into this. This video puts across a very complicated subject in a way that is simple to understand.
This is what keeps northern Europe mild in winter, if it collapsed we would experience the same conditions as in Siberia and Canada. Europeans would have to adapt to a much colder climate, you only have to study the little ice age (roughly 1500-1850) to see the effect this had on the continent with frequent severe winters, widespread crop failures caused by poor summers, which in turn caused famines, food for thought indeed.(no pun intended)
One of the most amazing changes in my lifetime is that the fabled Northwest Passage through Arctic waters is now basically open. It was still slammed shut when I was a child, as it had been for early European explorers. .
@@emotown1 The Earth isn't even 5 billion years old dude. As for the magma thing... You Emos make my head hurt. Just stick with the pole puffing thing lol 😂
@@AndrewCharnley ... And would you like to take our modern lifestyle back a 100 million years, or even thru an ice age and the a bit warmer / higher sea level last warm interglacial? You'd have to go back wearing animal hides and hunting bears, but you su don't have issues with that
In recent years there has been a apparent sharp increase in the rate of decline of the AMOC though it's hard to be sure as there are large year to year fluctuations. There was a large hesitation around 2009 which resulted in a 9cm sea level rise along the US East Coast albeit temporary. It reminds me of the splutters of a petrol engine that is about to run out of fuel. Stephan Rahmsdorf said him self that it may be that current models are overestimating the stability of the AMOC.
@@sammason2300 As the Gulf Stream moves north the water is deflected east by the rotation of the Earth aka the Coriolis effect. This lowers sea level along the East Coast. If the stream weakens then sea level to it's west rises.
WOW …. THANK YOU for making this video! Ive often wondered about this and have kept telling my kids, that here in Wisconsin, it seems like the planet is slowly shifting poles or something. Only bc the winters have not been the same since 1979. Our winters are much too warm. Thank you for making this video.
Hard to tell considering the chem clouds which is government interference. Most gardeners would doubt the CO2 story, considering plants are always starving for more. Its the same in Northern California where I have lived my life. Less and less rain since the 80s. Now our weather is more akin to Southern California patterns. Something is going on for sure.
Here’s a thought for your kids. Ask them how much the sea level will rise in the next 10 years. When they say 1-2 meters , say more like 1-2 centimeters. Then point to this guy’s nice chart showing O(1)mm rise per year. Once you ground their expectations in actual science you should be able to tackle the pole shift question with ease 😂

About 30 years ago I attended a lecture called, if I remember correctly, “Global Warming could mean the freezing of Paris”. The only thing that has changed since that presentation is how fast we are making it happen!
I think if we start using thirsty cement to not only reduce flooding but reduce sand use can help ecosystems recover and help the ocean a tiny bit. Also we should plant native flowers bushes cactus yucca trees succulents along the roads line them with native plants and reduce are pollution and reduce the heat.
This is probably a very naive comment but aside from a lack of political will, what would be the implications of a massive solar driven desalination plant in somewhere like Mauritania or Western Sahara. providing irrigation water to re forest these countries and using the salt bi product to resalt the oceans around Greenland? If we don’t implement a global survival policy we may be forced to accept a global annihilation policy
I think it's wilful ignorance at this point, oil is so profitable that governments are encouraged to plug their ears and shout till something catastrophic happens.
Your work is always a delight. I have to wonder if there would be seismic or volcanic response to the shutdown due to the high and low pressure systems in progress...
@grindupBaker Forgive my shallow speculations, my formal education is sadly lacking in most common geology. It is a beautiful process with nuances slow and swift, and I appreciate your explanation of one of so many movements in this world.
I live in Romania. Since about 10 - 15 years ago winters became very mild and almost no snow. Before, the winters were very snowy and cold. Nobody seems to care and very few take notice...
Past performance is no guarantee and all that, but humans are remarkably good at avoiding cohesion. There was a report they managed it once briefly, but were stymied - something about multiple languages. I'm glad to hear someone is studying the AMOC. While not distracting from the work on slowing general warming, might it be also good to begin preparations for the likely future state? How will we charge our iPhone batteries at least?
A number of obviously previous human species have gone extinct mostly due to climate changes. And when chaos happens and no one is able to cool the spent rods we will have massive Fukushimas and that will burn off the ozone layer and a barren rock will remain like Mars.
"How will we charge our iPhone batteries at least?" There is no WE. Figure it out. Democrats use iPhones and occupy Wall Street complaining about the very corporation that made the iPhones and iPads they carry into battle. Republicans use Android (and have solar power). Libertarians use Linux (and have solar power).
No time for learning in schools anymore. There`s an agenda to force into young skulls now. Besides, math is now considered racist so we have to lower all standards of education so nobody gets their feelings hurt or learns the truth about reality or real history. All of that must now be erased and rewritten to fit the new narrative of division and hate. Lots of money is at stake.
🤔More like graduate school. This is so far off the charts complicated that none of your students will notice the ocean is currently rising so slowly it would take 1000 years for a 1 meter rise. There’s no way you want kids to attempt to draw any conclusions from this presentation. Right now they need more concrete science; CO2 levels have doubled in 100 years. CO2 is s greenhouse gas. We want to keep CO2 emissions low since we don’t know if a runaway condition could be triggered
A decent amount of preparedness is always a good habit. Of course, if earth moves towards a direction of complete disruption, one might wonder what the point of living in such a future would be.
Why is there neither hypothesis nor thesis put forth here as to why this ocean system seems to collapse when there was no human induced global warming?
Thank you for an excellent presentation. Really good, and presented in a fair and balanced manner. But I am concerned that the general public are becoming more cynical about modelling and scientific predictions in general (hastened by the Covid fiasco). So meteorologists and oceanographers have their work cut out trying to get their message across. Keep going!
You lost your credibility when you denied the pandemic and insulted all the hardship and deathes caused by real sickness and of course made much worse by the stupidity of a certain delusional political right wing fanatical cult
Agreed, and this citizen ennui or fear about actual scientific facts translates into giving up or joining science deniers, such as those who believe in a global conspiracy to control people’s minds.
It just seems logical to me that we should learn to live in our environment without destroying it. Sustainability should always be the primary goal and focus. I am constantly amazed at how many people revel in destruction and misery.
There is more money in destruction and misery vs peace and harmony. Wars need money and politicians are invested in wars. Trump was the only President in decades that didnt start a war or continue one.
@xIcyStarzz "It's literally too late. All you can do now is get ready" The deadline passed 5 minutes ago. Or was it 40 years ago? It is difficult to keep track of all these predictions.
There is We and we should not prevent. Prevent is a mean to control. Controlling implies to alter the natural flow. Time on tine interfering with nature turns out to be a bad idea.
Human greed will continue to lead us towards the cliff and we won't realize how foolish we've been until after we've gone over the edge and it's too late to do anything about it. Great video btw!
Although I agree totally, I also believe we should burn as much fossil fuel as possible. Why? Because I'm convinced we've already passed several tipping points, and if you've booked passage on the Titanic you might as well go first class.
Likely no effect, unless you eat seafood or swim in the ocean. I'd imagine that the liver of the fish that you eat would filter out the plastic. Also, your skin should protect you from the plastic if swimming in the ocean. So overall, no significant effect and any effects are easily avoided by abstaining from seafood and ocean swimming/bathing.
@@Monaleenian you’re wrong actually, it doesn’t. Micro plastics are in the muscle of the fish as well and it’s unavoidable now. It’s also in non aquatic food as well. It’s so bad that humans now have micro plastics in us as well.
Climate is a non-linear process and subsequently cannot be modelled with any accuracy over extended periods of time. Many are treating theories, based upon general assumptions, as fact. They are not! Trying to regulate climate on the planet in any reliably predictable way is beyond the ability of mankind at this point and will remain beyond our ability at least for the foreseeable future. The climate will undoubtably change, and our resources should be directed towards adaptability. Adapting is what our species has proved to be extremely adept at.
Well said sir. As I understand this, the predictions were first made by Plymouth Marine Laboratory, soon followed by Wood's Hole Laboratory (USA) about 40 years astern. People laughed and scoffed. Today the initial timescale of 2 to 300 years has been revised to 50 to 100 years. As for the chances of global co-operation for reducing, even reversing the effects which we are beginning to see with our own eyes and hear about from climate sensitive industries like farming, wine production and fishing, to be realistic the chances of that happening effectively are nil. One only has to follow in general what is happening in South America, the Far East and Africa to see that huge regions are being decimated for profit caused by a combination of greed & the survival of a uncontrolled, rapidly expanding world population. Add to that equation the maniacal greed of the energy barons, who seize gleefully any excuse to drive up prices for their own benefit. These are the people responsible for most of the inflation since World War II that continues to impoverish the poor and inhibit governments. Our only realistic chance as a species is to arrest the power of the energy barons. There continues war provocative behaviour by many senior politicians who still harbour 18th century and earlier illusions of grandeur, the Iranian regime, Taliban, Russian government, Chinese, N. Koreans, Pakistanis and many in less high profile countries. To persecute the public with demands to reduce carbon output is just scratching at fleas so long as world industries continue to act without responsibility. That irresponsibility is not going to change in countries as far apart as China and Brazil. Adaptions like renewable farming & electric cars are a step in the right direction but not the answer due to the unsustainable cost of making batteries. The biggest villains are primarily OPEC, gas, electricity producers and so long as they remain unchecked, the save the planet equations ends with zero, nil, nada, rien. There is clearly danger in the oceans, "the answer my friends, is blowing in the wind".
This was already predicted in 1972 by a french scientist. He estimated 2025 to 2030 to start with a very severe drop of temperature between Greenland, Ireland and north of France
Thanks for the video (and others). They are really well presented and engaging. If more people were aware of the topics you discuss, such as this, there would be a greater knowledge and understanding for caring and respecting of planet Earth. Keep up the good work.
Why are climate engineering operations not being disclosed as the largest contributing factor to this collapse? The U.S military is completely manipulating our weather with technologies like HAARP. Upper level wind currents are manipulated thus effecting ocean currents. The elephant in the sky continues to be ignored to the peril of us all.
@@martincotterill823 yeah. Send the love to Chyna. Climate change is purely a western economic destruction tool unless they get into the game. Then it'll be a global economic destruction tool.
Thanks. I am not a climate scientist. I have a BSc in Technology and I was a Project Manager before I started the channel. So I am on a journey of learning, just like most folks.
My grade 8 environments study teacher 27 years ago said global warming will cause current changes and a current collapse would cause massive disruptions. Guess we’re still figuring this out
That's not really true. Governments aren't doing much, but many individuals are. More are taking up the baton every day. Eventually so many of us will have changed how we do things, that real changes will happen to CO2 levels, and other pollution as well.
@@jimthain8777 What's more, seeing an increased adoption of 'green' ways by the public will give governments more confidence that society is willing and ready to change and accept what might previously have seemed to be radical policies. I think that as a planet we are moving too slowly at the moment, but that as it becomes more normal to car pool and everything being electric, and people refusing to go back to car fume-poisoned air etc, and the realisation that global warming is undermining the way we currently live, the changes to slow down and mitigate the effects of climate change will accelerate. The question is whether they will accelerate fast enough to avert disaster.
@@jimthain8777 I appreciate your enthusiasm. During the pandemic when flights were closed many airlines kept flying empty planes because if not they would loose their gates and other benefits. Billionaires with private jets pollute more than a million normal people if I'm not mistaken with the number. Extraction of fossil fuels is growing in many places. Individual action is not nearly enough. Nothing is enough.
@@jimthain8777 Good way to look at it to have better sleep and mood. But there is no real connection with reality in those thoughts, unfortunately. Individual actions doesn't work on this scale.
It's great to see a channel like this discussing the AMOC, as well as mentioning Heinrich Events. What is even more interesting to me is how few people are talking about the fact that Heinrich Events, along with Dansgaard-Oeschger Events, in the past have caused up to 8°C of global warming within periods of time as short as 80 years. To put it into context, AGW has caused around 1.5°C of global warming since the Industrial Revolution.
Well, Heinrich and D-O events are pretty rare, for what that's worth. They appear to be pretty dramatic, though. They happen against a background of whatever the prevailing climate is, and the prevailing climate today is rapidly warming for well understood reasons. We should still deal with the immediate problem.
Hey Dave. I wanted to say thanks for caring. It came out wrong so I deleted my contempt at those small folks who refuse to try to clean things up. Then I realized I can do better. We all can. Anyhow your work here is appreciated.
I’m in the US so I’m not sure what the situation is in other countries, but I’ve been wondering how much of a difference could municipal composting make? I live in an apartment and don’t have space for a compost pile I used to have, I feel guilt whenever I put food waste in the trash. Is it as big an issue as I fear?
As always Dave thank you for all your hard work to keep us apprised of all the actual important news ( unlike what they show on the news channels ) regarding the climate crisis. Just wish more people would take note, realize we cannot carry on as we are and take action!! Cos as of right now the vast majority of people are sleepwalking into oblivion.
"we cannot carry on as we are" There is no WE. You choose for you and I choose for me. "the vast majority of people are sleepwalking into oblivion" But you are wise and smart and are NOT sleepwalking into oblivion! So, what exactly are you doing about it? Share your secret!
It's always "climate" and never the real problem, population. More and more people who need feeding and wanting more and more useless "stuff"....but I think Nature will sort us out in the usual way !.
I know what's sick is we could actually do this if we, as individual countries, focused & made a priority. But mankind is anything but greedy, short sided. It's sick how much evil corporate interests have destroyed this planet in the name of greed.
Mankind does not have a fixed nature. What were are is often unwilling to make a large collective change until it has become totally unavoidable. Individuals are greatly adaptable but our societies function by building on old foundations, we tend not to start afresh unless there is a complete collapse of the old system. The short sightedness is more a result of people being forced to keep their attention into the daily struggles needlessly imposed by a global paradigm of a select group of actors that promulgate a cult of finance that have coerced the bulk of humanity into toiling for their ludicrously indulgent gain. This fact has been tremendously well obscured and these actors keep us folks mired in petty conflict rather than unified enough to overthrow said paradigm. If you want to read more of how we prepare to undergo the necessary rupture to take ownership of our fates (or perish) I suggest China Miéville’s A Spectre, Haunting.
@@philipm3173 Forgive my short sidedness lol but indeed. The pandemic proved how callous and unforgiving our governments were yet all the while showering corporate interests in ready cash. While the common man loses everything. Amerika & Britain have been determined rogue nations that have pillaged the world's resources for their own. A disgusting legacy for these nations, shameful.
@@sableminer8133 what is important is for us to move beyond national politics. The old saying 'the working man (or person is a better option) has no country' must make a comeback. The governments are doing all sorts of awful things without our knowledge, nevermind our consent, and they do this on the behalf of the finance elite. So yes we should feel guilt if we are supporting an imperialist war and things like deforestation but we needn't feel some deep shame, instead we should do everything in our power to make it clear to those around us that humanity is not in this predicament by necessity and certainly not be some old-threadbare notion like our nature, but instead it is just a handful of rotten apples continuing a grotesque system that socializes us into being self-concerned to the detriment of all.
Pretty sure your 'millions killed, billions upset' price tag would likely be a result of climate change rather then a genuine effort to stop it. I mean, its already happening now. But there's a point to be had, its not going to be smooth since we delayed for so long. Slowing down requires more force the less time you have, but implying its hopeless and procrastinating on the brakes is hardly the smartest move.
@@Xeloboyo Genuine question interested in the specifics instead of talking about it in the abstract. Maybe there is a way of doing it without causing a lot of harm but I haven't really seen someone to come up with a clear comprehensive plan (weighing the pros and cons of each solution) to execute on yet.
If governments stopped subsidising fossil fuels and instead subsidised renewable energy + nuclear power. If people as a whole stopped eating meat or at least drastically reduced it, and we switched to regenerative farming practices and planted forests where the cattle used to graze (you need a lot less farmland for vegetarian/vegan food than for meat so the extra land could be reforested, the biggest driver of land clearing in Brazil is for cattle farming). If we invested in finding a low carbon version of concrete for building, and also focused on inventing a carbon capture technology. The fact we were able to create several COVID vaccines within a year with international cooperation and intense focus shows what humanity can achieve when it works together. I believe the same would be true of carbon capture. None of these ideas would kill millions or lower quality of life, indeed it could save millions. We know runaway climate change WILL kill millions and lower quality of life for billions.
@@ladyreverie7027 You are spot on. The problem is that we won’t do this because most people don’t recognise the issue as an emergency and never will, they do not wish to make changes, and this would impact massive vested interests (rather than humanity) hugely and they know how to manipulate opinion.
... Going through the comments below, it's obvious that people want easy answers and painless solutions to this, and all the other climate-related problems - problem is, there aren't any. One of the most common positions in denialism is that it's all happened before, so why should we care ? ... And the problem with THAT is that most of the events occurred so far in the past that modern Humans and their fragile civilization didn't yet exist . There WERE no New York Cities or Florida Ocean-Front properties then, Bangladesh and Holland were either uninhabited or had such slight numbers and nomadic lifestyles that it didn't matter. Smaller populations overall meant less need for agricultural land, and far less of that was near enough to the sea that salinity seepage of groundwater and the farmland it associated with was an issue ... This stuff ISN'T a problem for the future, it's happening now and if we continue to put it off, our children WILL pay for our indifference !
The AMOC stopping will naturally increase the ice coverage of the poles by decreasing temps of the poles. This will increase the ice coverage of poles which will decrease global temps and increase salinity of the oceans.
I think also its a kind of circuit. More global warming, more clouds, more rain, less sun shine... In the past , scientific have shown co2 concentration have never been cause of warming or frozing but everytime a consequence which act like catalyst. So we have catalyst something who ll.be arrived thousand years in the future.
Great content Dave. I often wonder why the scientists who publish their results seem to totally disregard any readers or people like you who help distribute the information. Those maps showing the cooling at the very top of the image and not even taking the time to color-differentiate land from sea are really disrespectful. I often think they do this because they don't really expect anybody to read or review their work. They have to publish, so they keep their jobs at universities, and the more they do, the higher the chance to be promoted. I seriously hope this will stop as content creators on the internet, like you, find the best-prepared results, not just some that cover the topic. AGI will help with that soon. Thanks for searching for us, your audience.
Axel, I think it's because the figure panels contain more than Dave went into here. The shore outlines are overlaid with multi-dimensional data on temperature, sea ice extent under different conditions and statistical significance. Filling in the shore outlines would have rendered part of that data illegible.
@@sfz82 yes, I saw that but having done studies myself that had results planned for presentation my professors had not let me get away with such disrespectful towards the audience images and graphics. It's not Dave’s fault. Just wanted to point out what this publish or perish approach often leads to
@@AMeierhoefer I think I don't understand what you would've liked to see instead. Colouring in shores underneath a false colour data map sounds like an awful idea. The same data would map onto different RGB values over land vs sea. And you'd add clutter to an already very busy, four-d map. All for the benefit of a hypothetical reader not recognising the outline of continents. But maybe you were thinking of something else I'm missing? At any rate - rest assured that publish or perish culture in empirical sciences puts a lot of value onto publishing in high impact journals such as this one. The system pushes scientists towards submitting what their peers perceive to be top notch to this kind of outlet, so I'm certain there was no shortage of tlc in preparing the figures.
@@sfz82 this is one kind of map projection. It shows earth rolled out flat in a square. There are other projections that show the main impact area much better and could have helped a viewer/reader understand the content. I agree with you that showing the shoreline’s eliminates a lot of people, at least in the US from even knowing what general area things are occuring. 😃
Im still baffled to why the UN would pay certain Pacific Islands large sums of money as long as they say they are being overrun by rising oceans when in fact they are experiencing the opposite ?
'Time to start prepping'? - time we had a government that acts on the basis of science rather than being hell bent on profit.
Thank you!
This is going to require a global human effort to save our asses. Unfortunately I'm not so optimistic that it'll happen in time. Humans tend to be ill believe it when I see it type and Unfortunately even though there seeing it it's easier to mock us and call us alarmist or conspiracy theorists than it is to face reality.

This triggered a memory of a snot nosed kid version of myself raising my hand to ask one of my favorite primary school science teachers; is it possible that ocean currents and temperatures could affect the flow of magma beneath the ocean floor like they do with the weather and winds, causing earthquakes and volcanic eruptions? My amazing science teacher looked like she was getting teary eyed. Looking back, it probably made her day.

I have lived in Alaska since 1977. Since 2008, we have lost much of the cold winter season. no longer did the Kenai Peninsula fall below -30 F in the winter. Average winter temps ate 24-35 degrees. Our summer temps have risen to the mid 70's from a mid 50 degree average. Worst of all, we have experienced massive dieoff of plants and animals. Most of our spruce trees have died due to the spruce beetle not being killed off in the winter months. First we lost starfish in the ocean. Then we had massive dieoff of birds and seals that fed on previous plentiful stocks of baitfish that are no longer present. In the last 5 years, our stocks of king salmon and chum salmon have crashed so bad that there are no longer catches of sport-caught salmon allowed even if all you want to do is catch and release. Commercial fishing using set nets have been closed due to possible catching a king salmon. Also crashing are the once prolific stocks of king crab and snow crab. There is a culprit here and it is the burning of fossil fuels. Burning of coal, oil and gas produces sulphuric acid. When sulphuric acid fall into the ocean, the water gets more acidic (acid rain) and that kills the base of our food chain, zooplankton. Since 1980, the presence of zooplankton in the North Pacific Ocean has decreased by 90+ percent. This also explains why the size of the king salmon that do return to spawn are less than 20lbs a piece. in 1990, the average size of kings returning to the Kenai River averaged 54-66 lbs with about 1/3 of the salmon exceeding 65 lbs with catches of 90+ pound fish occurring weekly.. Face the reality that the Pacific Ocean is dying. The Federal Court closed the last troll fishery for King Salmon in the Pacific Ocean to stop the dieoff of about 72 Orca whales that barely survive between Canada and Washington.
These facts you mention might still be caused by the natural cycle that stops the AMOC, since the AMOC has stopped many times before in the history of our planet. I do not deny that our polution has global consequences. But we have to know wheather the due stopping of the AMOC is solely caused by antropogenetic warming or that the natural cycle is the main mechanism. In the latter case there is no preventing the collaps of the AMOC and hence the next ice age.
As posted by someone else.....
The Arctic Ocean is warming up, icebergs are growing scarcer and in some places the seals are finding the water too hot according to a report to the Commerce Department yesterday from the Consulate at Bergen, Norway. Reports from fishermen, seal hunters and explorers all point to a radical change in climate conditions and hitherto unheard of temperatures in the Arctic zone. Exploration expeditions report that scarcely any ice has been met as far north as 81 degrees 29 minutes. Soundings to a depth of 3,100 meters showed the gulf stream still very warm. Great masses of ice have been replaced by moraines of earth and stones, the report continued, while at many points well known glaciers have entirely disappeared. Very few seals and no white fish are found in the eastern Arctic, while vast shoals of herring and smelts which have never before ventured so far north, are being encountered in the old seal fishing grounds. Within a few years it is predicted that due to the ice melt the sea will rise and make most coast cities uninhabitable………I forgot to mention that this report was from November 2 , 1922, as reported by the AP and published in The Washington Post 100 years ago.
The climate has been changing for 4,500,000,000 years, you cannot fathom that number and I bet the aholes destroying art can't even tell you what a billion is. BTW I am typing underwater in NYC since we have been under water for 23 years now.

A good video. Whether one believes in this doom scenario depends upon how much faith one has in scientific institutions. My experience working on the Great Barrier Reef since 1984 has left me like Christian who has lost his faith. I therefore have no idea what to think about this AMOC collapse phenomenon despite being a physical oceanographer. The doom stories about the Great Barrier Reef started in the 1960s and have been going on ever since. There are reports every month or so about how bad the coral is . And yet the latest statistics from the Australian Institute of Marine Science reveal it has never had more coral than this year. This despite 4 "devastating" bleaching events in just the last 6 years. The latest statistics demonstrate that many science institutions got it totally wrong about the reef. The institutions have been overtaken by groupthink. I have been calling for much better quality assurance in science institutions, something that got me fired in 2018. So, brilliant video, but there is now far too much evidence that much of the peer reviewed literature is greatly flawed. Until something is done about that, I remain a scientist to the core but a lost soul about the science institutions. Peter Ridd.

And increased snowfall isn't necessarily counter-indicative of rising temperatures. In fact, increased moisture in cold climes could be indicative of warming.
Agreed. These models are speculative at best and passed off as if they are fact. We don't have the understanding or model resolution and processing power to drive it to get to the accuracy needed for the claims made. Sure it is something of concern and the models might be partly correct, but we don't know.
History has shown again and again all these predictions to be wrong. The world has a large buffering capacity that addresses most of the sky is falling issues.
The issue is humans stubborn resistance to thinking beyond their own life span. Add this to little to no knowledge of the past. What we do know is basic physics of greenhouse gases. We have pretty good grasp of how much we're adding to our shared atmosphere, oceans. We also know there's no Oil Fairy refilling the holes with hydrocarbons. That the easy fossil fuel finds are nearly non existent. That these fossil fuels provide overwhelming majority of our fertilizer needs, feed stock chemicals for thousands of products. That a spike in their usage since industrial revolution has added 7 billion new humans with 80 million net new precious humans joining us annually. Business uses the idea of leading indicators and lagging indicators to guesstimate the health of their businesses. Problem with leading indicators is you generally don't recognize them until they pass by. For me this is enough to act on! Don't need 'six sigma certainty' or an impending collision with a civilization ending meteor. Thanks for video!
I can't see how you've got fired for calling for better quality assurances. At the very least you are omitting things here and biases opinion against institutions, leading the readers to agree with your statements by defamation, the readers here dont have access to either your firing case and the scientific publishing you mentioned.
That being said, pay for publishing and pay for reading scientific articles make for bad information flow. Even worse, only-positive-results publishing eschews scientific advancement, science should also note, pier-reviewed, what doesn't work, but there are no funds for that.
Worst, and related to your post, lack of revision for why certain predictions / published papers didn't pan out don't sell, thus we don't get funds for them.
The problem is most of the climate changes you’re describing we are unprepared to deal with. The solutions involve massive starvation and collapse of all industrialized economies as we know them.
they're gonna happen anyway, it just won't be volitional. But the effects of climate change will persiste even after our modern industrial society is gone
2 billion maybe. Another 4 barely surviving. Maybe 2 doing ok. Until the wars over livable land. We are in big trouble
I do enjoy your thoughtful take on things. Keep up the great work.
On a purely intuitive understanding I believe I will experience the AMOC stop flowing.

Yes, it will happen within the next 10-20 years or so, the Beaufort gyre is long overdue for spilling over. ruclips.net/p/PLHSoxioQtwZcqdt3LK6d66tMreI4gqIC-

Mammoths farting ?
@@jcoker423 IDK! Fred and Wilma Flintstone were living pretty high on the hog 🤣🤣
Exactly my thought. If it has collapsed multiple times, is this not just a cyclical event? Is green house gas the cause or something else? When I was a kid the climate science was predicting another ice age by now.
Exactly!!! That was the most important concept presented here.
That has always frightened me upon learning about this in the late 80’s in my geo-studies. The other big scare was learning about how much methane, and the potential of release with more warming of the arctic tundra.
The Nordstream pipeline blow up and the fragmentation of plastics is also a big source of methane
We need the aliens technology and we need them to tell us what we need to do we need their help, maybe this is why they're trying to force disclosure. I don't know but I do know that it's all true what they're saying about the aliens and the secret space program. Because of 1969 when I was only eleven years old and living in Roseville California I would see them anti-gravity craft come up every night on maneuvers look like they were training for something they were very organized I wasn't the only one who saw them in my neighborhood they were very high up though like satellites but it was definitely anti-gravity craft that could travel several thousand miles per hour and as I watched them for four whole years and they had two nights off per week they increased from thirty-five to forty up at the same time I kid you not I'm dead serious. I have never forgotten what I saw those many years ago then my father took a transfer to Houston and I have never seen any in Houston but I have heard others say they have seen them seeing is believing.
Should have been around in the 70's, when I was worried because scientists were worried about the upcoming ice age, which didn't happen.
@@retiefgregorovich810 well, I also remember that prediction but the methane makes co2 look like a child’s Chemical playset. Regardless, we’re all in for a ride and consequences.

Adapt2030. Humanity under attack
Unfortunately us humans have advanced so rapidly that we convinced ourselves that our silly imagined human world is all there is and everything outside of it is just there for our use.
Sure the weeds growing through cracks in the pavement always give me hope. While "intelligent" life may possibly be a short term self destructive phenomenon, life in all it's splendor has been through hellish periods before and is very capable of coming back from cataclysmic events.
Indeed we have known about this for the last 30 years. It's the old chestnut that won't go away. Helped of course by "The Day After Tomorrow" movie. I was in a tech support job by then, and all my fellow nerds were quizzing me on the movie, knowing my environmental background. The number of times I had to explain that, yes, what was being illustrated was absolutely possible, but no, not in the time span depicted by the movie. And further details thereafter. If I had dined out on every explanation I'd have ended up like Mr Creosote. Excellent informative video Dave, as always. I love those dropped articles. Do you do the graphics? I may have asked this one before.
@@martincrotty haven't given up hope that my quiet corner of this world will be mostly spared from cataclysm. That being said I bought a cabin in the woods and have that stocked and ready to sustain me for a year or so (without nuclear fallout so let's hope Russia simmers down 😅)
Civilization collapse usually happened when a society is too rigid to adapt, for instance mesopotamia wouldn't move their great capital when the region dried up of water, so eventually they became sand people and eventually died out (if I remember correctly). Now though, the hurdle to geographic shuffling to better climes is because everywhere is occupied already, most people can't afford to simply reshuffle. Personally, I had nothing to my name so moved with ease to somewhere I can live better, although it would be harder now as I've children and a home, but at least I'm living less dependent on rigid systems than the ones I used to struggle in (cities and then high cost of living areas). When the flood comes, now im part of a community that won't/can't lock me out of the arks. I wouldn't have children now if I hadn't moved far when it was a terrifying prospect full of risks, but taking the plunge seems to have paid off. Humans are adaptable, but other species are not and all need a spot in our neighborhood arks. Let's do what we can for our wild friends, whether that's leaving them space in the garden to nest, supporting conservation groups, switching to more responsible energies, etc. That awareness felt fruitless when I had nowhere to call my own, so I moved and it is better now. 🌝
You seem to have achieved my dream. I’m quickly approaching circumstances that would allow a potential relocation to somewhere else in the world to live out my life, in a manner that you describe.

@@richardsmith579 that's nonsense. Would you accept money to destroy the planet on which you and your family live? Then why do you assume "the experts" would?

Subtle climate denial? or just real unbiased un-politicised science, the simple truth is non of them or us really know, and we humans have no control over the universe. Live well now and the future will take care of itself.
If you post something that builds a human induced Co2 climate crisis you will get a lot of well read people who understand that this is a WEF agenda. Many also understand that the climate has always changed and will continue to do so whether we have a personal carbon credit system or not. Also scientists who study solar activity had predicted the coming 2030 freeze back in 2015 however they have now been silenced. Maybe you need to do some research yourself I’d start with the WEF personal blockchain linked carbon credit system.
What do you mean "Climate denial?" No one denies climate exists and changes. Just name climate prediction climatologists have gotten correct. Islands like the Maldives were predicted to have been flooded by now, they've risen by several meters. Our planet has benafitted from more co2. Our biggest danger is pollution, plastic in the ocean. What have you got to say about climatologists adjusting some of the records to make warming appear true, or worse than it is? I can provide graphs by NOAA and the IPCC that have removed the medieval warming period and the 1030s warming.

Thanks for a fascinating video with a clear explanation. I had read of the collapse of the AMOC in an article published about 20 years ago. It seemed to postulate that the result of the collapse would not be a planet overheating but that the event could usher in a new mini-ice age due to the resulting shift in ocean currents. Regardless, I have felt that what we are faced with globally is (and has been) something we as humans cannot really abort or effect even if we coordinated globally to cut our greenhouse gas emissions, etc. The best we can do is prepare for what is moving upon us in the form of such things as much more radical weather (i.e. hurricanes, tornados) as well as devastating sea level increases which will leave low lying areas such as Florida and most coastlines radically changed. This type of preparation the human race could actually do with success even at this late hour. But we fritter away invaluable time conducting useless climate control gatherings of heads of state and sign useless, unenforceable treaties and, in the end , remain in as bad a position or worse. Our governments and global organizations are the perfect example of the small orchestral violins playing on the deck of the Titanic as the ship slips below the waves. The best efforts that can achieve some sort of security is what can now be done on the personal individual scale. Do not rely on your government to save the day. They are too busy performing the political calculus to really produce a safe , secure outcome for anyone other than themselves.
Well said, John.
Though you have expressed your ideas very well, it would be good to remember that Floridians (highest spot: 345 ft.) can move to Georgia (plenty of land over 1,000 ft. and highest spot: 4,500 ft.) (Might do well to stay away from Alabama, though; Edgar Cayce predicted southern Alabama would sink.)😏
Holland has some land 6 meters below sea level (That's minus 20 ft.) and yet they have been able to cope and even to drive back the sea for hundreds of years, even BEFORE they had electric pumps.
In the German language one says, "Es wird nicht so heiss gegessen als gekocht!" ("You don't EAT the soup as hot as you COOK it!" meaning: There are LOTS of theories going round (believe it or not, making us hotter AND colder) and all from good scientists, but not ONE of them knows all the details of what it's going to be like in even forty years... a few things, maybe; everything: NO WAY! Fogedabodit!😉
“Do not rely on your government to save the day.” This is why I do not trust Republicans on global warming. This is your mantra and you derive conclusions from it rather than from what you see. You know well that the only institution even remotely powerful enough to stop global warming is government which you are ideologically opposed to. It is in your interest therefore to deny anthropogenic global warming, so that government will not expand. I warn you that this foolish and myopic viewpoint will come to haunt the Republican Party, particularly in places like Florida.
I do not believe in anthropogenic global warming because scientists tell me to. I believe it because it aligns with the evidence that I see and logically follows from things that science taught before we realized anything about global warming. In the past, like the during the age of the dinosaurs, the earth was significantly warmer as a result of higher CO2 levels. That CO2 was sequestered into the crust and the earth cooled, so much so that our era, the Cenozoic, is far colder than that in which the dinosaurs lived. Indeed were it not for volcanism plants would eventually freeze the earth solid. We have spent one and a half centuries releasing the Carbon that warmed the earth in previous eras. Therefore, we should expect the earth’s climate to resemble that of previous eras on account of our activity. This is an entirely logical assumption and we have photographic evidence of it happening.
Of course, the story is slightly more complicated in its details, though not in it’s conclusion. Usually volcanism is slightly more effective than sequestration, for most of the past half a billion years the earth has been free of ice caps. Indeed it’s not as if volcanism has been absent from our present Cenozoic era, in fact it’s been relatively steady. Both volcanic carbon emissions and carbon sequestration by plants have both been relatively steady. So why did it change? Well there is another reason why the earth cooled that had nothing to do with the continuous sequestration of carbon. At the beginning of the Oligocene Antarctica froze solid because of the Antarctic circumpolar current, that and the formation of the isthmus of Panama are the real reason why the Cenozoic period has been so cold. Our oceans will “fight” against global warming so to speak because its circulatory system has feedback mechanisms that favor a colder climate rather than a warmer one. But those mechanisms mitigate normal fluctuations in the warmer direction, and this not a “normal” fluctuation. The fossil fuels we burn are added on top of the steady volcanic emissions, and that is happening on a scale that’s orders of magnitude faster than plants could possibly sequester it. The effect that this has is not business as usual; it is much more akin to the eruption of a large igneous province, like the flood basalts of old. Except this time there are no flood basalts, we are dumping the CO2 into the atmosphere. If we keep dumping CO2 into the atmosphere the feedback mechanisms keeping the Cenozoic “ice house” climate in place will be overwhelmed, and the climate will go back to what it was like during the age of the dinosaurs.
Bite the bullet, you need not do anything unconstitutional. Even under a strict originalist interpretation, the Tax and Spending Clause combined with the power to raise tariffs gives Congress all the power it needs to fix this problem. The longer you wait the more extremists there will be demanding more “radical” solutions.
So, the experts don't come to the same conclusions?? So much for climate experts! Let's work on things we CAN make a dent in (eliminate waste, war, etc.).
I agree , weve globally unanimously come to the same basic conclusion that something is definitely happening. 🤔 most go to the denial. . To prepare and stay aware .

Surprised Dave didn't mention the north Atlantic 'cold blob' which is a dramatic illustration that the AMOC slow down is well underway. Part of the North Atlantic is now cooler than at anytime since records began about 80 years ago, and that's in a warming world!
No it isn’t. There was a temporary cold Atlantic blob for a year or two, totally normal and happens frequently.
Still there in November 2022, expected to remain until the 2050’s.
There is a tiny anomaly in the western North Atlantic about 1.5c max divergence at the surface.

The Thermohaline circulation might collapse, but it won't stay that way for long. The waters around the equatorial line would become excessively hot and the water around the poles would frozen, increasing salinity of the water near the poles and then moving south towards the equatorial line, thus, restarting the circulation. However, the direction of the circulation might be different.
Not for long is a very relative term. Either way it would be catastrophic in the short term and for a long time after.
@@lrvogt1257 Yup, "not long" could easily be a decade (or more) before the salinity disparity is great enough to kickstart the circulation again. Once halted, that is a lot of water to get moving again.

@@dalel3608 Long is a relative term. It would certainly be long enough to be catastrophic.
@@markhemsworth2670 Nah, he used a lot of words to denigrate someone else who DID say something useful, positing a plausible theory -;))
Happy to be proved wrong but I think the system wouldn't be a simple jump in climate - it would tend to oscillate for a thousand years or so before stabilising in a new equilibrium.
If AMOC shuts down then the North Atlantic gets colder. This reduces ice melt from Greenland which tends to allow AMOC to start up again. Once started Greenland melts again which kills off AMOC once more.
I did see a graph many years ago showing this pattern at the end of the last ice-age, although I couldn't find that graph again. The change in temperate was dramatic - complete step change. After a few years there was a step change back to the original temperature for another few years, then repeat.
This oscillation in climate would effectively kill agriculture - it is very hard to grow stuff when you've no idea what climate you are in.
There are multiple studies of paleoclimate changes which were massive temp changes that occurred within a few decades or less. Some of the oscillations are very extreme and rapid according to some studies.
@@dannybrashear5857
Yes.
Oceans currents are well known phenomenon and their cycles are 60-65 years from warm to warm ( or cold to cold ).
Now they are turning to cold phase again. North Atlantic Oscillation (NAO) and Arctic Oscillation (AO) are already in cold phase .
Last time when this happened we were under ice-age threat which suddenly changed to AGW when they turn to warm phase 1978.
Now it´s time to panic coming ice-age again (AGC - maybe?).
Climate science use these normal changes as possibility to make money.
All studies (there were plenty) which proved this oscillation are hidden somewhere because they don´t support climate change (AGW) script.

I built models for govt and corps for many years. even with advanced computers it is really difficult to take into account inter-actions of all the systems: eg. sea water termp, salinity, and atmospheric circulation, east/west, south/north. with the wild card of eight or nine tipping points that can pop off randomly it all gets impossible to predict with a high degree of certainty. this is why global warming pace consistently surprises scientists. that aside, all of us need to take climate action to heart. not sure how anyone can prep to survive it. but perhaps we can delay the inevitable.
Danke!
There is nothing you can do to strengthen an argument more as to make your point clearly and calmly.
I'd be calling that job done...
Your point about the models is the key, in my view. There are many variables and indeed many interdependent systems that make the accurate modelling of climate change extremely challenging. Ocean circulation is just one of these systems. To make matters worse, the collections of systems itself is not static. For example, consider the effect of more CO2 on vegetation. We have already seen a 15% increase in planetary "greening" owing to rising CO2 levels. We could ask, what influence does this "greening" have on ocean circulation and vice versa?
Accurate climate forcasts would surely have to include the prime heat generator.
Basically all chrophyll converts sunlight into atmospheric heat. The green you see is what isn't converted.
Excellent presentation, well documented and presented in a way that is easy for the ordinary folks like me to understand. Thank you very much . Expect more such videos.
What caused the AMOC collapses that happened before man was a factor? Are these collapses the actual onset of ice ages? Do not understand the term "equilibrium" as it applies to Ice Ages and Warm Interstial Periods. Change seems to be the order of the day re temperature.

This is what keeps northern Europe mild in winter, if it collapsed we would experience the same conditions as in Siberia and Canada. Europeans would have to adapt to a much colder climate, you only have to study the little ice age (roughly 1500-1850) to see the effect this had on the continent with frequent severe winters, widespread crop failures caused by poor summers, which in turn caused famines, food for thought indeed.(no pun intended)
One of the most amazing changes in my lifetime is that the fabled Northwest Passage through Arctic waters is now basically open. It was still slammed shut when I was a child, as it had been for early European explorers. .
...sure but interesting to note that these cold areas, Antarctic in particular, was for much of the past 100 million years a tropical paradise.

In recent years there has been a apparent sharp increase in the rate of decline of the AMOC though it's hard to be sure as there are large year to year fluctuations. There was a large hesitation around 2009 which resulted in a 9cm sea level rise along the US East Coast albeit temporary. It reminds me of the splutters of a petrol engine that is about to run out of fuel. Stephan Rahmsdorf said him self that it may be that current models are overestimating the stability of the AMOC.
Can you say a bit more about the temporary sea level rise? I find this an odd concept outside of tidal and weather timescales
@@sammason2300 As the Gulf Stream moves north the water is deflected east by the rotation of the Earth aka the Coriolis effect. This lowers sea level along the East Coast. If the stream weakens then sea level to it's west rises.
WOW …. THANK YOU for making this video! Ive often wondered about this and have kept telling my kids, that here in Wisconsin, it seems like the planet is slowly shifting poles or something.

Hard to tell considering the chem clouds which is government interference. Most gardeners would doubt the CO2 story, considering plants are always starving for more. Its the same in Northern California where I have lived my life. Less and less rain since the 80s. Now our weather is more akin to Southern California patterns. Something is going on for sure.
Here’s a thought for your kids. Ask them how much the sea level will rise in the next 10 years. When they say 1-2 meters , say more like 1-2 centimeters. Then point to this guy’s nice chart showing O(1)mm rise per year. Once you ground their expectations in actual science you should be able to tackle the pole shift question with ease 😂

Good work. You were right.

Also we should plant native flowers bushes cactus yucca trees succulents along the roads line them with native plants and reduce are pollution and reduce the heat.

I think it's wilful ignorance at this point, oil is so profitable that governments are encouraged to plug their ears and shout till something catastrophic happens.
@@vaga4239 I think it's criminal.
its all bullshit.

Your work is always a delight. I have to wonder if there would be seismic or volcanic response to the shutdown due to the high and low pressure systems in progress...
@grindupBaker Forgive my shallow speculations, my formal education is sadly lacking in most common geology. It is a beautiful process with nuances slow and swift, and I appreciate your explanation of one of so many movements in this world.
If AMOC slowing down wasn't due to anthropogenic influence, it'd be the biggest co-incidence since co-incidences started annoying people.
This has been eye opening! Thank you for sharing this! I am definitely looking forward to your next post
Very nicely presented as usual
Thanks a lot
I live in Romania. Since about 10 - 15 years ago winters became very mild and almost no snow. Before, the winters were very snowy and cold. Nobody seems to care and very few take notice...
Mild is bad?
The lighting is so much better on this video. Well done!
Agreed... but face could use a bit more contrast.
Thanks Andrew. I think we finally got there!
Past performance is no guarantee and all that, but humans are remarkably good at avoiding cohesion. There was a report they managed it once briefly, but were stymied - something about multiple languages. I'm glad to hear someone is studying the AMOC. While not distracting from the work on slowing general warming, might it be also good to begin preparations for the likely future state? How will we charge our iPhone batteries at least?
Your iPhone battery will be the least of your problems.
@@incognitotorpedo42 I think he knows that :)
A number of obviously previous human species have gone extinct mostly due to climate changes. And when chaos happens and no one is able to cool the spent rods we will have massive Fukushimas and that will burn off the ozone layer and a barren rock will remain like Mars.
"How will we charge our iPhone batteries at least?"
There is no WE. Figure it out. Democrats use iPhones and occupy Wall Street complaining about the very corporation that made the iPhones and iPads they carry into battle. Republicans use Android (and have solar power). Libertarians use Linux (and have solar power).
Android? Dont leave us out.
Thank you for your clear and realistic videos
People are actually paying attention to this now, because we have a couple decades left, not a couple centuries. peace earth.
Love your graphics and delivery- great subject . This ought to be part of all middle school/ high school science classes

@@JustHaveaThink 🌎: " 🙂🖐" ..................
No time for learning in schools anymore. There`s an agenda to force into young skulls now. Besides, math is now considered racist so we have to lower all standards of education so nobody gets their feelings hurt or learns the truth about reality or real history. All of that must now be erased and rewritten to fit the new narrative of division and hate. Lots of money is at stake.
🤔More like graduate school. This is so far off the charts complicated that none of your students will notice the ocean is currently rising so slowly it would take 1000 years for a 1 meter rise. There’s no way you want kids to attempt to draw any conclusions from this presentation. Right now they need more concrete science; CO2 levels have doubled in 100 years. CO2 is s greenhouse gas. We want to keep CO2 emissions low since we don’t know if a runaway condition could be triggered
Best explanation of the AMOC thanks
Thank you :-)
A decent amount of preparedness is always a good habit. Of course, if earth moves towards a direction of complete disruption, one might wonder what the point of living in such a future would be.
Birth rate proofs Gen z are smart 😂
Why is there neither hypothesis nor thesis put forth here as to why this ocean system seems to collapse when there was no human induced global warming?
ikr. its like these videos are just here to scare-bait us to click these videos. Climate fears sell i guess.
Thank you for an excellent presentation. Really good, and presented in a fair and balanced manner. But I am concerned that the general public are becoming more cynical about modelling and scientific predictions in general (hastened by the Covid fiasco). So meteorologists and oceanographers have their work cut out trying to get their message across. Keep going!
You lost your credibility when you denied the pandemic and insulted all the hardship and deathes caused by real sickness and of course
made much worse by the stupidity of a certain delusional political right wing fanatical cult
Agreed, and this citizen ennui or fear about actual scientific facts translates into giving up or joining science deniers, such as those who believe in a global conspiracy to control people’s minds.
It just seems logical to me that we should learn to live in our environment without destroying it. Sustainability should always be the primary goal and focus. I am constantly amazed at how many people revel in destruction and misery.
There is more money in destruction and misery vs peace and harmony. Wars need money and politicians are invested in wars. Trump was the only President in decades that didnt start a war or continue one.
Nightmare fuel. We should be prevving (preventing), not prepping.
We’re now forced to do both
"We should be prevving"
There is no WE. Prev if you wish.
@xIcyStarzz "It's literally too late. All you can do now is get ready"
The deadline passed 5 minutes ago. Or was it 40 years ago? It is difficult to keep track of all these predictions.
There is We and we should not prevent. Prevent is a mean to control. Controlling implies to alter the natural flow. Time on tine interfering with nature turns out to be a bad idea.
You got a plan to keep the ocean running?
What I found most striking was the animation of the AMOC. It reminded me of videos of cloud circulation on Jupiter.
Convection.
Physiscs is the same in all places.
So there could only have been an AMOC when the continents are in this particular setup. What kind of current existed during Pangea?
Human greed will continue to lead us towards the cliff and we won't realize how foolish we've been until after we've gone over the edge and it's too late to do anything about it. Great video btw!
Human greed and the fact that we've put it in the driver's seat of society
Although I agree totally, I also believe we should burn as much fossil fuel as possible. Why? Because I'm convinced we've already passed several tipping points, and if you've booked passage on the Titanic you might as well go first class.
Just valuable contributions to society from this excellent presenter. Thank you
What is your opinion on microplastic in the oceans and there effects on our bodies in the future?
Right now*
Likely no effect, unless you eat seafood or swim in the ocean. I'd imagine that the liver of the fish that you eat would filter out the plastic. Also, your skin should protect you from the plastic if swimming in the ocean. So overall, no significant effect and any effects are easily avoided by abstaining from seafood and ocean swimming/bathing.
@@Monaleenian you’re wrong actually, it doesn’t. Micro plastics are in the muscle of the fish as well and it’s unavoidable now. It’s also in non aquatic food as well. It’s so bad that humans now have micro plastics in us as well.
Climate is a non-linear process and subsequently cannot be modelled with any accuracy over extended periods of time. Many are treating theories, based upon general assumptions, as fact. They are not! Trying to regulate climate on the planet in any reliably predictable way is beyond the ability of mankind at this point and will remain beyond our ability at least for the foreseeable future.
The climate will undoubtably change, and our resources should be directed towards adaptability. Adapting is what our species has proved to be extremely adept at.
Well said sir.
As I understand this, the predictions were first made by Plymouth Marine Laboratory, soon followed by Wood's Hole Laboratory (USA) about 40 years astern.
People laughed and scoffed.
Today the initial timescale of 2 to 300 years has been revised to 50 to 100 years.
As for the chances of global co-operation for reducing, even reversing the effects which we are beginning to see with our own eyes and hear about from climate sensitive industries like farming, wine production and fishing, to be realistic the chances of that happening effectively are nil.
One only has to follow in general what is happening in South America, the Far East and Africa to see that huge regions are being decimated for profit caused by a combination of greed & the survival of a uncontrolled, rapidly expanding world population.
Add to that equation the maniacal greed of the energy barons, who seize gleefully any excuse to drive up prices for their own benefit.
These are the people responsible for most of the inflation since World War II that continues to impoverish the poor and inhibit governments.
Our only realistic chance as a species is to arrest the power of the energy barons.
There continues war provocative behaviour by many senior politicians who still harbour 18th century and earlier illusions of grandeur, the Iranian regime, Taliban, Russian government, Chinese, N. Koreans, Pakistanis and many in less high profile countries.
To persecute the public with demands to reduce carbon output is just scratching at fleas so long as world industries continue to act without responsibility.
That irresponsibility is not going to change in countries as far apart as China and Brazil.
Adaptions like renewable farming & electric cars are a step in the right direction but not the answer due to the unsustainable cost of making batteries.
The biggest villains are primarily OPEC, gas, electricity producers and so long as they remain unchecked, the save the planet equations ends with zero, nil, nada, rien.
There is clearly danger in the oceans, "the answer my friends, is blowing in the wind".
We just haven’t evolved as a species. I hope the next civilization gets it right.
Good job explaining a complex topic. Thank you.
Can't tell if the uncertainty or the consequences are more frightening...I have more questions than answers after watching this video
yep, we either all gonna die or we get rid of capitalism asap.
This was already predicted in 1972 by a french scientist. He estimated 2025 to 2030 to start with a very severe drop of temperature between Greenland, Ireland and north of France
Thanks for the video (and others). They are really well presented and engaging.
If more people were aware of the topics you discuss, such as this, there would be a greater knowledge and understanding for caring and respecting of planet Earth. Keep up the good work.
Spread the word, send links to Dave's videos
Thanks MrEd. I appreciate your feedback :-)
Why are climate engineering operations not being disclosed as the largest contributing factor to this collapse?
The U.S military is completely manipulating our weather with technologies like HAARP. Upper level wind currents are manipulated thus effecting ocean currents.
The elephant in the sky continues to be ignored to the peril of us all.
@@martincotterill823 yeah. Send the love to Chyna. Climate change is purely a western economic destruction tool unless they get into the game. Then it'll be a global economic destruction tool.

Thanks. I am not a climate scientist. I have a BSc in Technology and I was a Project Manager before I started the channel. So I am on a journey of learning, just like most folks.
So Snowpiercer or Waterworld?
Both lol
No, the 6th mass extinction.
My grade 8 environments study teacher 27 years ago said global warming will cause current changes and a current collapse would cause massive disruptions. Guess we’re still figuring this out
I really like your videos, very well done. Too bad they are usually quite depressing! Nothing is happening to really address climate change
That's not really true. Governments aren't doing much, but many individuals are. More are taking up the baton every day. Eventually so many of us will have changed how we do things, that real changes will happen to CO2 levels, and other pollution as well.
@@jimthain8777 What's more, seeing an increased adoption of 'green' ways by the public will give governments more confidence that society is willing and ready to change and accept what might previously have seemed to be radical policies. I think that as a planet we are moving too slowly at the moment, but that as it becomes more normal to car pool and everything being electric, and people refusing to go back to car fume-poisoned air etc, and the realisation that global warming is undermining the way we currently live, the changes to slow down and mitigate the effects of climate change will accelerate. The question is whether they will accelerate fast enough to avert disaster.
@@jimthain8777 I appreciate your enthusiasm. During the pandemic when flights were closed many airlines kept flying empty planes because if not they would loose their gates and other benefits. Billionaires with private jets pollute more than a million normal people if I'm not mistaken with the number. Extraction of fossil fuels is growing in many places. Individual action is not nearly enough. Nothing is enough.
@@jimthain8777 personal lifestyle change even on a worldwide scale is not enough to stop climate change, we need systemic revolution.
@@jimthain8777 Good way to look at it to have better sleep and mood. But there is no real connection with reality in those thoughts, unfortunately. Individual actions doesn't work on this scale.
Thanks Dave, great job. Much appreciated.

His name is Dave.

Weakest it's been for 1600 years. Life thrived back then. Life adapts. What's the problem?
It's great to see a channel like this discussing the AMOC, as well as mentioning Heinrich Events.
What is even more interesting to me is how few people are talking about the fact that Heinrich Events, along with Dansgaard-Oeschger Events, in the past have caused up to 8°C of global warming within periods of time as short as 80 years. To put it into context, AGW has caused around 1.5°C of global warming since the Industrial Revolution.
Wow...
Well, Heinrich and D-O events are pretty rare, for what that's worth. They appear to be pretty dramatic, though. They happen against a background of whatever the prevailing climate is, and the prevailing climate today is rapidly warming for well understood reasons. We should still deal with the immediate problem.
That was a fun thought experiment. Nice to think more on the systems that govern climate and play out scenarios.
Hey Dave. I wanted to say thanks for caring. It came out wrong so I deleted my contempt at those small folks who refuse to try to clean things up. Then I realized I can do better. We all can. Anyhow your work here is appreciated.
"I deleted my contempt at those small folks"
That is unwoke. Perhaps "height challenged" would be a suitable euphemism.
@@thomasmaughan4798 funny. Un woke indeed. From a BFI non the less.
I’m in the US so I’m not sure what the situation is in other countries, but I’ve been wondering how much of a difference could municipal composting make? I live in an apartment and don’t have space for a compost pile I used to have, I feel guilt whenever I put food waste in the trash. Is it as big an issue as I fear?
Lol not a big deal
Without China and India on board, no matter what you do will be a waste of time, energy and resources. Have fun
Great video! How about a video about dark aerosol (mostly tire particles) effects on melting the ice in the Arctic? Thanks!
@grindupBaker not diesel, high sulphur bunker C fuel
As always Dave thank you for all your hard work to keep us apprised of all the actual important news ( unlike what they show on the news channels ) regarding the climate crisis.
Just wish more people would take note, realize we cannot carry on as we are and take action!! Cos as of right now the vast majority of people are sleepwalking into oblivion.
Unfortunately, the majority of people live in the developing world and are having this done TO them.
Cheers Rob.
"we cannot carry on as we are"
There is no WE. You choose for you and I choose for me.
"the vast majority of people are sleepwalking into oblivion"
But you are wise and smart and are NOT sleepwalking into oblivion! So, what exactly are you doing about it? Share your secret!
It's always "climate" and never the real problem, population. More and more people who need feeding and wanting more and more useless "stuff"....but I think Nature will sort us out in the usual way !.
@@grizzlednerd4521 I dunno. They're having trouble getting insurance in Florida.
I know what's sick is we could actually do this if we, as individual countries, focused & made a priority.
But mankind is anything but greedy, short sided. It's sick how much evil corporate interests have destroyed this planet in the name of greed.
Mankind does not have a fixed nature. What were are is often unwilling to make a large collective change until it has become totally unavoidable. Individuals are greatly adaptable but our societies function by building on old foundations, we tend not to start afresh unless there is a complete collapse of the old system. The short sightedness is more a result of people being forced to keep their attention into the daily struggles needlessly imposed by a global paradigm of a select group of actors that promulgate a cult of finance that have coerced the bulk of humanity into toiling for their ludicrously indulgent gain. This fact has been tremendously well obscured and these actors keep us folks mired in petty conflict rather than unified enough to overthrow said paradigm. If you want to read more of how we prepare to undergo the necessary rupture to take ownership of our fates (or perish) I suggest China Miéville’s A Spectre, Haunting.
@@philipm3173 Forgive my short sidedness lol but indeed. The pandemic proved how callous and unforgiving our governments were yet all the while showering corporate interests in ready cash. While the common man loses everything. Amerika & Britain have been determined rogue nations that have pillaged the world's resources for their own. A disgusting legacy for these nations, shameful.
@@sableminer8133 what is important is for us to move beyond national politics. The old saying 'the working man (or person is a better option) has no country' must make a comeback. The governments are doing all sorts of awful things without our knowledge, nevermind our consent, and they do this on the behalf of the finance elite. So yes we should feel guilt if we are supporting an imperialist war and things like deforestation but we needn't feel some deep shame, instead we should do everything in our power to make it clear to those around us that humanity is not in this predicament by necessity and certainly not be some old-threadbare notion like our nature, but instead it is just a handful of rotten apples continuing a grotesque system that socializes us into being self-concerned to the detriment of all.
Maybe it’s collapse is the circuit breaker on global heating.
Meanwhile, policy changes here in the US inch their way along towards addressing climate change... Corn growing may be impacted slightly!
How do we do what you suggested at the end of the video without killing millions and lowering the quality of life of billions?
Maybe that's the plan only the mega rich get to survive.
Pretty sure your 'millions killed, billions upset' price tag would likely be a result of climate change rather then a genuine effort to stop it. I mean, its already happening now.
But there's a point to be had, its not going to be smooth since we delayed for so long. Slowing down requires more force the less time you have, but implying its hopeless and procrastinating on the brakes is hardly the smartest move.
@@Xeloboyo Genuine question interested in the specifics instead of talking about it in the abstract. Maybe there is a way of doing it without causing a lot of harm but I haven't really seen someone to come up with a clear comprehensive plan (weighing the pros and cons of each solution) to execute on yet.
If governments stopped subsidising fossil fuels and instead subsidised renewable energy + nuclear power. If people as a whole stopped eating meat or at least drastically reduced it, and we switched to regenerative farming practices and planted forests where the cattle used to graze (you need a lot less farmland for vegetarian/vegan food than for meat so the extra land could be reforested, the biggest driver of land clearing in Brazil is for cattle farming). If we invested in finding a low carbon version of concrete for building, and also focused on inventing a carbon capture technology. The fact we were able to create several COVID vaccines within a year with international cooperation and intense focus shows what humanity can achieve when it works together. I believe the same would be true of carbon capture.
None of these ideas would kill millions or lower quality of life, indeed it could save millions. We know runaway climate change WILL kill millions and lower quality of life for billions.
@@ladyreverie7027 You are spot on. The problem is that we won’t do this because most people don’t recognise the issue as an emergency and never will, they do not wish to make changes, and this would impact massive vested interests (rather than humanity) hugely and they know how to manipulate opinion.
Excellent presentation. You made the science very accessible to me. Thankyou for your calm approach to such a potentially difficult subject
... Going through the comments below, it's obvious that people want easy answers and painless solutions to this, and all the other climate-related problems - problem is, there aren't any.
One of the most common positions in denialism is that it's all happened before, so why should we care ? ... And the problem with THAT is that most of the events occurred so far in the past that modern Humans and their fragile civilization didn't yet exist .
There WERE no New York Cities or Florida Ocean-Front properties then, Bangladesh and Holland were either uninhabited or had such slight numbers and nomadic lifestyles that it didn't matter.
Smaller populations overall meant less need for agricultural land, and far less of that was near enough to the sea that salinity seepage of groundwater and the farmland it associated with was an issue ... This stuff ISN'T a problem for the future, it's happening now and if we continue to put it off, our children WILL pay for our indifference !
Great presentation. But I fear our lack of empathy for our fellow humans means we will continue on the current path.
I fear you are right.
The AMOC stopping will naturally increase the ice coverage of the poles by decreasing temps of the poles. This will increase the ice coverage of poles which will decrease global temps and increase salinity of the oceans.
I think also its a kind of circuit.
More global warming, more clouds, more rain, less sun shine...
In the past , scientific have shown co2 concentration have never been cause of warming or frozing but everytime a consequence which act like catalyst.
So we have catalyst something who ll.be arrived thousand years in the future.
You guys didn't watch the video.
many americans cannot take in this information because of our education system layered with training by corporate media
Great content Dave. I often wonder why the scientists who publish their results seem to totally disregard any readers or people like you who help distribute the information. Those maps showing the cooling at the very top of the image and not even taking the time to color-differentiate land from sea are really disrespectful. I often think they do this because they don't really expect anybody to read or review their work. They have to publish, so they keep their jobs at universities, and the more they do, the higher the chance to be promoted. I seriously hope this will stop as content creators on the internet, like you, find the best-prepared results, not just some that cover the topic. AGI will help with that soon. Thanks for searching for us, your audience.
Axel, I think it's because the figure panels contain more than Dave went into here. The shore outlines are overlaid with multi-dimensional data on temperature, sea ice extent under different conditions and statistical significance. Filling in the shore outlines would have rendered part of that data illegible.
@@sfz82 yes, I saw that but having done studies myself that had results planned for presentation my professors had not let me get away with such disrespectful towards the audience images and graphics. It's not Dave’s fault. Just wanted to point out what this publish or perish approach often leads to
@@AMeierhoefer I think I don't understand what you would've liked to see instead. Colouring in shores underneath a false colour data map sounds like an awful idea. The same data would map onto different RGB values over land vs sea. And you'd add clutter to an already very busy, four-d map. All for the benefit of a hypothetical reader not recognising the outline of continents. But maybe you were thinking of something else I'm missing? At any rate - rest assured that publish or perish culture in empirical sciences puts a lot of value onto publishing in high impact journals such as this one. The system pushes scientists towards submitting what their peers perceive to be top notch to this kind of outlet, so I'm certain there was no shortage of tlc in preparing the figures.
@@sfz82 this is one kind of map projection. It shows earth rolled out flat in a square. There are other projections that show the main impact area much better and could have helped a viewer/reader understand the content. I agree with you that showing the shoreline’s eliminates a lot of people, at least in the US from even knowing what general area things are occuring. 😃
Im still baffled to why the UN would pay certain Pacific Islands large sums of money as long as they say they are being overrun by rising oceans when in fact they are experiencing the opposite ?
Because it's all a money making racket and a fear mongering exercise, based on modelling systems that can't possibly have accurate data input
