If you take a look at global temperature graphs that span millions or billions of years, you can see that our planet’s temperature has made wild swings. In fact, the Earth used to be completely covered in snow and ice! So, what’s the big deal about a few degrees of warming today? In this episode of Weathered, we take a deep dive into Earth’s climate history in order to better understand our current moment.
Weathered is a show hosted by weather expert Maiya May and produced by Balance Media that helps explain the most common natural disasters, what causes them, how they’re changing, and what we can do to prepare.

What usually doesn’t get brought up enough is the previous cooling and heating spells that the earth has gone through that were only quick in a geological sense, are associated with huge die offs. 75-95% of all species die offs. We are changing the climate 100-1000 times faster than many of those. It’s not just humans at risk, it’s all things that grow, crawl, swim, and fly. Everyone needs to shed this denial and waiting for the next generation to fix it. I have hope but very little.
When warm period was the cause of dying off ?
Pre Pliocene. The sudden warming caused the flooding and mass die offs. Much of it is found in permafrost
Capitanian mass extinction event, the probable cause was mass volcanic eruptions.
It's avoidable if climate movements will stop trying to kill carbon capture startups.
@@thehimself4056 thank you. I would have had to look it up. I am certainly no scientist but I do nerd out and watch a lot of science shows. Life on Our Planet narrated by Morgan Freeman touched on a lot of the die offs throughout history and how life barely survived. That’s why I love watching PBS shows and follow this channel.

@@ecurewitz It's not the billionaires; it's the billions.
And yet the climate has never really been stable.
The Medieval Warm Period that warmed the climate to where it is today.
The Medieval Cool Period that lead to the little ice age.
Then about the time the climate started warming up again became the starting point that human cause climate cooling/warming/change proponents started their measurements as proof that humans are to blame for whatever the climate starts trending to over a few years or decades.
Today they say the climate change is very rapid, more so than it ever has before, 1 to 2 degrees Celsius over the past 100 years or so. Totally unprecedented in all of history.

Abrupt Climate Change
Around 15,000 years ago, the Earth started warming abruptly after ~ 100,000 years of an "ice age"; this is known as a glacial termination. The large ice sheets, which covered significant parts of North America and Europe, began melting as a result. A climatic optimum known as the "Bölling-Allerød" was reached shortly thereafter, around 14,700 before present. However, starting at about 12,800 BP, the Earth returned very quickly into near glacial conditions (i.e. cold, dry and windy), and stayed there for about 1,200 years: this is known as the Younger Dryas (YD), since it is the most recent interval where a plant characteristic of cold climates, Dryas Octopetala, was found in Scandinavia.
The most spectacular aspect of the YD is that it ended extremely abruptly (around 11,600 years ago), and although the date cannot be known exactly, it is estimated from the annually-banded Greenland ice-core that the ANNUAL-MEAN TEMPERATURE INCREASED BY AS MUCH AS 10°C IN 10 YEARS (emphasis added).
Close quote.
I wonder how humans dumping CO2 caused such a rapid climate change 11,600 years ago. Maybe humans are so powerful they found a way to send our CO2 back through time into the past since they are claiming that the only reason that the climate changes is because humans cause the change.
Perhaps you can explain how humans burning fossil fuels caused those two sudden warming events thousands of years ago.
@@UCCLdIk6R5ECGtaGm7oqO-TQ yeah, all of us billions fly everywhere in personal jets.
If you are a farmer you understand. A slightly later last freeze in the spring or a slightly earlier first freeze in the fall can wreck your whole year. At the same time many plants require a winter freeze for a certain number of days, and many trees cant tolerate any freeze. Our farms and food supply infrastructure and economies are built upon stable, predictable yearly temperatures.
Then we are fools.

I'm sorry to disappoint this optimistic young lady with my comment. I'm well old enough to have witnessed a drastic change in climate over my relatively (in geologic terms) very short time as an observer. In-my-lifetime is an incredibly short amount of time considering the temporal scale of past temperature swings. The science is clear. This is not a red flag, it's a five alarm fire. It's an existential threat to us and millions of other species. Life will survive, but perhaps not without a major reboot. Rebooting nature is not something our species will survive. We have responded very poorly to something we've known for decades due to.....greed. Too little too late shall be our collective epitaph.
well said
You didn't witness anything like the Cambodians in Angkor who after building the city for 600 years all vacated from drought Around 1390). Or the Vikings who settled in Greenland and all died off when the climate got colder. Or the peasants of Chamonix France in 1601 who had to leave their village because the glacier was overtaking it. Get the book "A Cultural History of Climate". It's a good read.
Good thing the second coming of christ will come before then.
As a side note it's interesting that just a month or two of covid lock downs fixed a good portion of the ozone layer. So if something happens causing the global populations manufacturing to get disrupted and halted and changed, we will be fine. Well, those of us that survive a world war 3 purge will be fine.
I work in biodiversity conservation in developing nations, and have done so in 'developed' nations as well. Given what I see and experience every day regarding people, politicians, and corporations we will not be making the changes needed at the magnitude necessary or within the time frame needed.
At present by 2100 we are already looking at a conservative estimate of twice the previously predicted sea level rise (Nerem, et al 2018 Climate-change-driven accelerated sea-level rise detected in the altimeter era), and that's accelerating.
There is a significant portion of the population, and and even higher percentage of those in power, who won't even consider doing anything until it's far too late, then they'll argue over what to do and continue to find ways to not do anything other than hold meetings to argue and blame everyone else.

That's just not what the human race has done historically, people want their children and children's children to prosper, not live in the mass famine of ecological collapse.
Faith is either blind or based on passed events. To have faith that humanity can solve this is of the blind variety. There is no evidence that the selfish nature of humans can be switched off. The majority of people could want to reverse the trend, but don't want to pay the price. Those in power will always want to maintain the status quo. Things always change after the event with humans. We'll survive, but not without tremendous social upheaval first.
To deny humans capacity to innovate their way through a crisis is to ignore history itself. Stop pretending your misanthrope urges are legitimate criticism.

a lot of the warming happened because of europe and america.
Unfortunately, in my opinion, the people who choose to watch videos like this are probably already doing their best to minimise their fossil fuel consumption across transport, packaging, etc.
The people who need to be convinced are those driving petrol and diesel powered vehicles larger than they really need, the management of polluting companies. Without them getting on board with us, politicians will continue to pay lip service to what we know needs to be done while telling us, "Now don't you worry about that."
Yeah, but that is miniscule compared to our skies being filled with all of these aircraft, cargo, passenger, nothing has been done to clean up these massive polluters, this has exploded, all of these cargo ships, shipping us our China trash, while filling our oceans with garbage, many places to start, well let's pick on the little guy that is already driving a perfectly clean car just trying to get to work.
Any individual person reducing their CO2 has no real impact on the environmental CO2 levels at all, you can only address this with massive national level structural and regulatory changes.
Yes it is far more effective for the people who care about the issue to focus on democratically changing the system so that the default choice - the one most people will always take - is the green choice.
E.g. if you have to go out of your way to get a gas car, most people will get an electric one. If you have to seek out a specialty shop to get a new gas furnace, most people will just get a heat pump. If you have to go out of your way to get a plane ticket instead of a train ticket for your 300 mile trip, most people will take the train.
Most people just want to live their life, so the wya to get them on board by making the green choice the easy choice.
@@wintermath3173 All that being said, don't forget climate change is a scam, it's a lie so our communist leftist government can continue to take more and more control of your life, there is no climate crisis.

Imagine a world where the ports don't work due to sea-level rise. Then factor in the desertification of agricultural lands and we may not have the ability to feed the people. That will bring the three horsemen. Famine, disease and war. I'm normally optimistic in nature. However my life has shown me humans are very tribal and typically going to protect their own interest in the first place. I have a group of friends I am meeting this week. All smart and successful professionals. The four blokes are in long term relationships with kids and houses and have nine cars in the four families. They all know climate change is serious but the safety and comfort of their families comes first. I doubt that will change in my lifetime.
I live in a port city and the lake (Lake Superior) has lost over 6 feet in depth in the last 5 or so years due to a drought from record high temps. We're already seeing the effects of climate change here.
I use to receive a lot of family newsletters for Christmas. And they all proudly report the usual lifestyle that got us into this mess: living in big houses, driving fossil cars, not caring about global effects of their diet, buying nice stuff for everyday living, travelling to nice locations all around the planet by plane, sometimes on several occasions per year, children studying abroad etc. etc.

Seems more and more likely, scenario SSP5-8.5 of the IPCC assessment may come to fruition (or at least the higher end of the spectrum). I say enjoy what you can, while you still can; pity the generations to come.
Yes future generations will probably be worse off, but our own generation will face a lot of the effects before we die. Hell, just wait 4 months and see what that summer is gonna be like.
The weather patterns in my area of the midwest have changed. We are 10-20 inches of rain less than what people are used to for going on 5 years now. What that shows up as is long periods of drought broken by brief intense rains that the current landscape is unable to adequately capture. Its crazy that I find myself simply hoping it is a decade long change like what lead up to the Dustbowl, as opposed to a permanent climate shift.
"The weather patterns in my area of the midwest have changed." Yeah, I'm in the Cleveland area and winter finally decided to show up two days ago.
Why not mention how going to a plant-based diet reduces an individuals carbon footprint and is much easier to do than give up burning fossil fuels. 🌱⛽️🌎

And we could all do that while also reducing the amount of fuel we burn.

Yes, we can make the changes needed to evade disastrous climate change!
But we will not do is, and there are many reasons for that.
The most powerful & influential of those reasons is how it would affect our civilization & lifestyle in a very unpleasant & undesirable way almost immediately which would affect everyone in industrialized, modern countries most severely (because virtually every aspect of our lives depend on these fuels)! And the effects would be the very worst for those who have been benefiting the most from the sale of fossil fuels. Their control of the resources & the massive amounts of money they have made gives them a tremendous amount of power, leverage & influence over the matter.
Doing nothing will be far more disastrous than improving our technology which is a boon to the economy. It always is. Your right that the fossil fuel industry is causing the problem because they have the geo-political power to profit from it.
Humans cannot even handle the smallest changes without panicking. We need to prepare for these changes - get people ready for when (not if) the coastal dwellers have to move inland, get us ready for intense heatwaves, doing things like talking to roofing companies about making light colored roofing standard, how to use drapes correctly to lower electric use.
Simple answers are usually wrong-for example, your suggestion to make light coloured roofing standard. Why? Where? Maybe not in cold climates? Maybe not in well insulated new construction? I think it would be better to choose the roofing material and colour based on best local practices, and do the same with all other aspects of new construction. There are no (correct) simple answers to any of this.

Also were not only changing the climate through fossil fuels but also agriculture and infrastructure. We pretty much destroyed the best places on earth for our enjoyment, while plants and animals have to survive on the margins and have far less resources left to adapt to rising CO2 levels.
That we are not adapting our current fossil fuel burning infrastructure to renewable power sources faster is because the fossil fuel companies have most of the politicians taking exhorbitant amounts of money from them to keep their industry going. Citizens United,, the Supreme Court’s ruling stating money is really just free speech and free speech is guaranteed under the constitution, allows corporations to spend unlimited amounts of money a lot of which they earn through taxpayer supported programs subsidizing the fossil fuel industry. Sweden has developed roadways that charge ev’s as they drive over them. Think what it would mean to have every major highway in the world capable of this . The technology exists today to do it. The reason’s it’s not being implemented is political will power bought and paid for by corporations . Find out what you’re voting for before you vote .
When you're honestly thinking about it surface temp swings encourages shifts in biomes and migrations etc. What about water temp. Shifts in temp for the ocean currents and oxygenation levels when reefs die off etc.
I don't live in the ocean. 2 anoxic events in the long stable Cretaceous not sure if a true anoxic event on the Eocene itself some 15my long or 5X as long as our ice age
Primary producers love still ocean. Rafts of algae and simple plants fill aerated top feet in the 🛁 warm sea water, every sunny moments pent photosynthetic happiness. Ocean may look green from space
Their decomposition at sea floor ties up the oxygen and sets up process of new coal
Elegant system.
Before you get carried away, of the 1.5 degrees C of warming that the IPCC warns of, 1.1 degrees has already occurred.
During that period, human lifespans have DOUBLED and the number of deaths from extreme weather events have dropped by 98%.
Try researching some of the positives that have come out of this, rather than focussing solely on the negatives.
For example, due to the increased CO2 agricultural yields have consistently risen at almost twice the rate of population growth.
That means we're better able to feed ourselves than ever before.

I like climate change, it'll depopulate much of the world 😂.
The expansion we're experiencing is due to the combination of industrialization and the greed of wealth that is driven to remove obstacles from maximizing the accumulation of wealth. One of the barriers to that kind of expansion was labor. I expect it will be organizing into grass roots unions that will be the only limiting factor to cut the waste that the wealthy push for in their haste to harvest everything. The wealthy will not bow to requests. It needs to be pressured. And I think organizing is the only way to stop it from pushing the planet into an abyss. Just a thought.
Thing is, the wealthy is just about everyone here now in this comment section. Everyone lies somewhere on the scale, and most here will lie at the upper end of that scale.
Knock it off. Every country, political & economic system has energy needs. To act like it's all the fault of capitalism is foolish, however you wish to disguise your 'workers paradise'. Besides, those unions will mean jack & diddly as automation increases it's capacity & capabilities. If you're pinning your hopes on that sort of pressure, it's misguided.
@@UCCLdIk6R5ECGtaGm7oqO-TQ That is incorrect. Relative wealth is irrelevant, when most of us may/may not be wealthy enough to live our lives with a first world living standard- whereas billionaires are extremely powerful individuals which have the financial resources and connections to influence entire governments more reliably than even a hundred thousand souls put together.
@@brianhirt5027 The act of funding think-tanks and media to scam and manipulate the public against their best interests because these companies don't want to go through the inconvenience of naturally switching to alternative sources of energy is absolutely the fault of capitalism. Capitalism has no solution for this. On paper, it assumes consumers and the wider public will act rationally in our own interests. We often don't.
Also, automation increases the urgency of change. Capitalism may not survive total automation. Without the means for everyone to work, or an adequate way to survive while acquiring skills leading up to those few high-complexity jobs that may remain- people aren't just going to sit down and starve. Either a UBI gets established, or heads will start rolling. The rich can get away with a lot, but throughout history they always push it too far. If they had any sense, they'd stop building doomsday bunkers to run away from problems THEY helped cause, and instead try to keep the people placated better.
Wow. I really struck a nerve. Good. I must be on the right track, then. And it's the same kind of straw manning as well. "Worker's paradise?" Nice try to conflate this with some kind of pipe dream of utopia. The current world state isn't a product of fulfilling "energy needs." It's a drive to reach the pinnacle via excess and greed. And trying to "what about" everyone as guilty, and therefore complicit doesn't change the fact of where we're headed because of a repeat of civilization collapse. It's always a product of excess. Resource depletion always rests in the wake of dead civilizations. And Capitalism can best be summed up as the best way to direct the most resources to the fewest hands in the shortest amount of time. Full automation is going to lead to a dystopia because those directing it will end up turning to government for protection from those they care nothing about. You want to try to pretend someone is looking for a workers paradise in order to halt any return to an equilibrium. But the privileged feel oppressed by the thought of equality. There's nothing foolish about seeing the actual imbalance that wealth creates.
Maelstrom is correct... Wealth is influence. And that influence has been used to manipulate the system to benefit them at the expense of drawing resources necessary to support a society. They've been put in check before. It can be done again. The amount of energy and resources they're willing to put in to halting it is the dead give away.
The interesting part of this video for me was the fact on how it all began. first starting with the cynobacteria, then utilising methane to create oxygen through photosynthesis. Which led to the creation of ice on earth. Then creating the albedo affect, cooling earth. Personally I found that it was shocking to see that it took 300 million years for the earth to cool down.

The point is important. The climate is destabilizing, but at rate of change beyond any that could occur naturally. So the vulnerability is with us. It is our civilization that cannot handle uncertainty. Although, I’m concerned other animals will be unable to adapt, because evolution is gradual.

Actually quite weird "they" want to hang on to those units. Fought furiously to be free from the imperia, yet keep using the imperial units :)
In any measurement system, the message is still the same. Rapid climate change will be catastrophic.
@brandon9172 For scientists working in ultra-cold physics, yes. But for the daily lives of ordinary people, the freezing and boiling points of water are directly observable and make more sense.
Since 1 degree Kelvin = 1 degree Celsius, the utility of the scale depends on its usual purpose, not on esoteric science.

"Don't worry the earth will continue just fine W/O mankind " - which is not really the issue.

Compliments! I'm a geologist and as such I fully realize the different rate of change in today world with respect to even the fastest climate change in PETM. We are using past energy in a blink of an eye in geological time. However we should stress that past environment was not constrained in adaptation by human activities as is now and this strongly esacerbate the problem. Huge deforestation, overuuse of soil, biodiversity collapse are all important factors to add to the mere climate change we are facing. As professor said is up to us to make the change and, in my view is less painfull that we, as "evoluted" world we thought

And man made geothermal by using deep drilling and pipes filled with ammonia based chemicals suited to the local change in temperature between ground and air. If the air is getting warmer, then the difference between ground and air is increasing which makes it easier to capture energy between the temperature gradients.
it's not about the few degrees, it's about the impact that few degrees brings. rising sea levels, more violent storms, harsh droughts, water oxygenation, and more. there's a reason why sudden changes in temperature are found with mass extinctions.
Sea level rise is 3.2 mm/yr according to satellites that read sea level rise.
@@abelgarcia5432 : On average... but sea level does not rise evenly due to currents, winds, and geology. A small difference during a storm can create exceptional storm surge. A warmer atmosphere holds 7% more water vapor per 1º C so rainfall increases dramatically. As climate gets warmer sea level rises faster.

Very scary. Like 4 feet seal level rise in the next 70 years if we don't limit climate change. Everybody can made a positive difference by supporting climate change required to limit climate change increase to 1.5 C increase by 2030 changes and having it balance out at that level. Every human can make a difference.
Can we? Certainly. Will we? Absolutely not. It does not jibe with the worship of money, and therefore will not happen.
We have innovated our way out of or through previous crises, and we will this one too. Do better & broader reading of economics & history for a more measured & informed perspective.
This came at a great time. I was thinking of this exact thing this morning.
I find it so tedious to listen to climate deniers rattle on about how the climate has always been changing. What they fail to consider is that none of those other climates could have sustained civilized human life the way the climate of the past 12KY have.
We are sooooo fortunate to have this particular climate and to have kept it as long as we have. If we let it change we’ll lose everything because everything relies on stable climate.
Too late to stop it. See my other comments, in this list, for possibilities to deal with it.
This is two pronged issue. The climate denialists are a problem yes. But they're quickly being relegated to being in the same space as flat earthers. Nobody serious takes them seriously. What is of greater concern is all the climate activists war on carbon capture startups, which represent our best chance at getting the carbon emissions under control.
Also if it is natural, who cares? You know how many natural things we've altered for our benefit? How is this any different.
@@brandon9172 As the video says, we've had large temperature rises within humans time on this earth, but it was 100 times slower than now. So our low numbers back then were able to adapt. When we were not on the planet, one of the biggest heat spikes we've discovered was 10 times slower that what's happening now. We are actually in a period where the planet is going into cooling, due to the sun tilting away from the earth. But we have pushed our climate into a rapid heating instead, through the greed of the last century & looks like, the next century also. That's how it's different. The seas levels are due to raise by a meter by the end of this century, but they won't keep going at that pace. By the end of the millennium it's guesstimated that we will have 60m sea level rise & that will keep going. Crops will fail, almost everyone in that time will be displaced ...life will get hard. Unless you are pretty rich. People will look back at us, in our time & think what the hell were we thinking
@@fo4urm640
Yes I understand all that. My issue is with the argument that climate change deniers often make, which is that "its natural so its okay and we should do nothing about it". That entire premise is stupid because it implies we cannot or should not alter natural things for our own benefit. IF climate change actually was natural (which its not), we should still do things to reverse or minimize it. Our entire civilization, humanity, all of it exists because of our capability to alter our surroundings, so why exactly should we just roll over and die in that scenario? Makes zero sense.
It´s the *rate* of change that´s the problem. We can comfortly sit in a car accelerating from 0 to 100km/h in 20 seconds. Increase the rate 100 times and everyone´ll understand how that´s a problem....
It's both the rate of change and the absolute amount of change in the next couple of decades. The high amount of change pushes the Earth over more tipping points. Unfortunately the sensitivity of temperatures to CO2 levels appears higher now than scientists thought a decade ago.
CO2 is not a thermostat we have fine control over.
I think of our influence on climate more like the sport of curling. Once the climate has momentum we can either brush like crazy to speed it up (like burning fossil fuels like no tomorrow), or we can stop all activity, but the climate will now continue on its path, we can't "stop it". Once we stop encouraging it to go quickly we sit back and hope it stops where we wanted it to.
I’m a bit disappointed that no mention was made of the Earth’s previous major extinction events, for comparison with the holocene extinction.
Its largely avoidable if people will stop trying to kill the myriad of new carbon capture startups. Enviromental movements are busy bees sabotaging & blacklisting every single carbon capture startup trying to get on it's feet right now under the mistaken impression they're all some sort of shell game from big oil.

I like reading comments about people not wanting to change. They don't get it. We change or die. Pretty simple to me.
Change is the only constant but we are no longer just passive observers.

What's going to happen, is going to happen. In the next [insert number of years here], a comet may reset earths clock. Imagine going through centuries of misery to reduce Co2 only to be wiped out by a giant rock.
Just enjoy what time you have here. Go for a walk, pick up any trash you find and say, _"I love you"_ to people you love, because one day, sooner or later, we'll all be gone.
Property tax is going to go up in Miami to cover all those sea walls, that's for sure. Whereas carbon capture might be important 50-100 years from now, right now it makes no sense to burn coal for power, and then use power to capture carbon... Economically, it's far more sensible to just not burn the coal... The problem is accountability, until a proper and strict global and UN security council enforced carbon credit market is setup there will be no end to this because the polluters aren't paying their fair share, countries are subsidizing them instead of making due all the negative externalities that they produce.
From the long term average, it looks like we’re on the cool side and should warm up a few degrees.
What has the time earth was a glowing rock to do with our optimal temperature today?
The optimal temperature is the temperature the current ecosystem and our society is optimized for and that is not a few degress higher.

Humanity has a long history of doing what is necessary to survive, but seldom ever taking a more optimal path. We have unprecedented knowledge and technology to do better today, but one doesn't have to look far to see that the people haven't changed much. If I were to predict the future, I would say that humanity will survive climate change and that some adaptations potentially included forms of geoengineering will have to be employed along the way. There is little doubt that we could and should do better, but I don't think our odds of that are good. Everything from war, to poverty, to racism, and even our responses to pandemics has shown me that humanity is trying to solve complex challenges with a collective intelligence that barely surpasses the average ape. We're just smart enough not to kill ourselves off, but the intelligence of individuals does not appear to manifest on the scale of the collective actions of the species.
TLDR? We will survive to regret not doing the obvious thing.
I am not as confident as you about the chances of humans surviving this coming apocalypse. I won't go into the details.
I don't understand why some climate scientists are against geoengineering. Without that we are doomed, just stopping CO2 emissions (which we need to do) doesn't guarantee at all we will have a stable climate, many natural things could push as out of the precarious equilibrium of the last 11,000 years and we will be in a major problem.

It's worse than that really as well, current climate models are very cautious and haven't historically accounted by CO2 and methane released from permafrost thaw. There's twice the CO2 trapped in permafrost than in all of the Earth's current atmosphere, four times the amount that humans have ever released.

I find most of the information here incorrect.
The problem is not that humans need to adapt. The problem is that everything else needs to adapt, in particular microorganisms.
Since we started our human caused temperature increase near the top of the already natural thermal maximum - the Earth temperature is rocketing up above the maximums any current species on Earth has ever seen.
EVERYTHING on Earth has spent the last million years adapting to this temperature or cooler. NOTHING is adapted to warmer global temperatures, as we have spent the last million years cooler than today.
So this is unknown territory, new change, asking ALL species to adapt.
Probably OK for humans, we can migrate and build buildings and such.
But what about the microorganisms? They may either die off or massiveley bloom with these changes.
The problem is that microorganisms as they are today are responsible for things like our Oxygen, and our food. If we kill or bloom certain key microorganisms we all just die, quickly, like nearly instantly from a historic perspective.
So yeah...maybe we should reduce our harm like NOW. The longer we continue our damage the more likely we kill ourselves in mass human tragedy and possible extinction. Good luck everyone!
The Earth will be just fine. All the animals (people) will suffer, but the Earth will just keep on keeping on.
Well, golly. So what? Earth will remain a spherical object orbiting the sun. That's a great comfort to our children.
@@lrvogt1257 Not the point.
The pitfall of looking at temperature data is that it is on a time delay since the oceans are absorbing excess heat.
Instead, try looking at CO2 increase. According to that data, we passed the point of no return in the 1980's.
There's no way of pulling trillions of tons of carbon out of the atmosphere that we put there. Even with this information in hand, global carbon emissions are still accelerating.
We're locked into a +10C increase over the next couple centuries, but mass extinction will happen around +3-4C. We blew past the 1.5C threshold earlier this year. Now permafrost melt at the poles will release even more CO2.
Hope that our leaders would stand up to big oil and create a new, clean energy system was a pipedream since the majority of them are in the pocketbooks of big oil.
Allowing money into politics was a horrible idea.
Have you been reading my mind? That's exactly the same understanding, that I've come to. I'm preparing a "lifeboat", to migrate wherever the climate is survivable. In fact, it's literally a boat, a Hunter 34, and with small garden aboard, with fishing, seaweed, and being mobile, I hope to ride the Terrible Times out, with a companion, passing on my knowledge to a new, hopefully wizened, new generation.
How did you become so smart---lololol
JUST BECAUSE YOU CAN'T SEE IT DOESN'T MEAN IT'S NOT POSSIBLE. Humans have innovated their way out of previous crisis & we'll innovate our way out of this one too. Knock it off. You want to be a misanthrope, then at least have the civility to refrain from expressing it online. You accomplish nothing by sabotaging hope.
There are ways of not only pulling CO2 out of the atmosphere in huge quantities but also of quickly cooling the planet.
Not saying we'll agree to do what needs to be done but it's definitely possible. The biggest problem right now seems to be getting people to accept that the solution is, by definition, irresponsible geoengineering that's doing something stupid and unsustainable...because... Trillions of tons of extra waste is eventually gone and you close down.
I think your data might be a little wrong. +10c over a few hundred years is WAY over even the worst projections. 10 years ago we were heading for an increase of +4 - 5c, but current projections are at around +2.8 - 3.5c ...with a concerted (probably unlikely) effort i think we could get that down to +2c. Which is still an absolute ecological disaster, but nowhere near the devastation you suggest. The temperatures are done on an average over several years, so although this +1.5c was a bit of a blow, we are hoping it's a blip due to the El Niño. But time will tell & tipping points are likely to be reached. Also the mass extinction already started, welcome to the ecopocalypse.
@@fo4urm640 Then get out there and start preserving genetic legacies of threatened ecosystems. If enough people do that we should have the ability to reboot them down the road.
*I am a Harvard Educated Geologist. We knew that the earth has been getting hotter for the past 18,000 years! Also Ocean water levels have risen 380 feet in the last 18,000 years as glaciers started melting. We know for a fact glaciers melt when the earth gets warm and Grow back when the earth gets Colder Again! This cycle of heating and cooling has happened 738 times in the last 1,486,000 years. I don't have any Denial that its going to get 14 degrees hotter in the next 60,000 years since I have known about it since 1960 when I graduated school! The Geological Record is filled with millions of pages of hard data proving that THE ICE-AGE CYCLE is REAL! Also mother nature has 99.9999% more power and influence over the ICEAGE than the Activity People Do! One Volcano can cool or warm the earth with the way more power than 18,000,000,000 Cars driving for 1500 years. Get a life, learn about what's coming and buy same nice tropical fruit tree seeds for making tropical smoothies and enjoy this TROPICAL AGE which is coming no matter how high you raise taxes in an attempt to stop it! Don't forget your 'Sun Tanning Lotion' folks, It’s going to be a hot one for the next 60,000 years and the Sun is only going to get hotter and hotter as the Earth ages so enjoy your Iceages whenever they crop up!*
Unfortunately the Milankovitch Cycles are in a cooling and not warming cycle.
There were also no vulcanic eruptions of the size you talked about.
If you're a harvard educated geologist, what's your issue with paragraphs?
@@Bogwedgle *_I use speach to text AI software and it's not perfect. The END of the Ice-age is real, just google it. Ask any Mammoth or Saber tooth tiger or ice evolved animal why they suddenly died during the last 12,000 years. This is not human caused but a new Solar-Maximum starting up. Your a Democrat tring to prove my post wrong since my grammar is off. Old tactic. I have seen it all my life._*
I like to tell people, sure, you can accelerate faster than the speed of sound, then decelerate back to a rest. That's totally safe, if the rate at which your speed changes is slow enough.
But if you go from the speed of sound to zero in an instant, you turn into a pancake.
And it's the same way with climate change. Sure the planet has been +10c warmer than it is today, but it got that warm very slowly. Right now, we have our foot on the gas, quite literally, and aren't going to let go until we come up against a wall of human caused mass extinction.
Nice analogy.
Incorrect. There's literally dozens of carbon capture startups that have launched in the past two years. Many of them look quite promising. The doom prognosticators assume a static destruction. They either ignore or dismiss human capacity to innovate their way through a crisis. Even though we have many, MANY times before.
@@brianhirt5027 Carbon capture could be compared to the parachute in the above example. It can help to slow you down, but it doesn't protect you from stopping too fast.
@@BanjoGate seems to me in another 50-100 years our inheretors will have the capacity to dial up or down the earths thermostat at will. Considering the scales involved i'd imagine we'll be able to do so with incredible incremental accuracy. We want it warmer? We slow down carbon capture. We want to it cooler? We pull more carbon out than's going in.
People will not give up their toys just to save a "planet". Can you really see people giving up their cars and lawns?
Y'know what people hold on to even more dearly? Grudges. Enviromental movements are busy bees sabotaging & blacklisting every single carbon capture startup trying to get on it's feet right now under the mistaken impression they're all some sort of shell game from big oil. The grudge has made them blind to nuance, made them blind to the human capacity to innovate a way through a burgeoning crisis.
Yeah I can. But they need walkable cities first, and people need to think about local plants when they are designing landscapes.
Lawns are lame. Get a cactus.
Tbh the issue is mostly up to industrial use of fossil fuels. Industries use so much more than our "toys" do.
Yes, if you love your children and their children then you will change everything over to electric as fast as you can and insist that all utilities change to solar/wind and power storage and shut down fossil fuel power plants. Yes, it is totally doable... check out Tony Seba as to how it is actually much much cheaper than what we have now and that electric power might become almost free if we do it.
American lives are not capitalist, they are consumptive. We only exist to buy disposable products. Engineered garbage. How much of what we buy can’t be repaired or isn’t designed to live more than a year or two. The only way we will survive is to stop producing plastic garbage and only use our existing garbage to produce new products. No more extraction of resources.
After the impact that killed off the dinosaurs would of been a 5 or 10 year global cooling from all the debris in the Atmosphere no sun no plant life no food. Another interesting thing with warming is more evaporation and more cloud cover and more rain. And of course more extreme weather. Having more trees and plant life might be a way to help with the soil erosion that will eat away at the earth we have above sea level. Water can change this planet faster then we can.
I wrote a local newspaper editorial in 2009 about climate change: Our actions can influence more than values. What would your editorial say with that kind of a title?
Not wanting to trivialize the value of human life, but admitting that we are reaping what we sowed, I would like to believe that “it's ok... the planet will repair itself, it will adjust naturally”. Now, what about the nuclear issue, all these plants and waste? What will happen when chaos ensues? Thinking about the planet, that's what I find most disturbing.
Nuclear plants create FAR less waste than any other energy source other than completely renewable energy sources, and the amount of energy you get from nuclear vs the amount of waste it generates is vastly different from oil or coal, nuclear energy is clean energy.
@@BossDrSample that's not my point. It's not about comparing this and that under 'normal' situation. What I meant is: what will happen to the plants and waste when there are no people or conditions to manage them?
Nuclear plants require a super sophisticated society to maintain them. Many, will "die", as the society around them withers. Not many, if any at all, have the Boron "final shutdown" system, that military systems do. Background radiation is bound to rise, as terrible accidents happen. Only 4 plants, south of the Equator, so I recommend moving very far south, to minimize the hazard: along the Magellan Strait, for example.
440 Plants on the globe. They will explode. After that - no more live on earth. Nowhere.
The meltdown of a couple of NPP's will destroy the ozone layer in the upper atmosphere.
You'll get a weird sun burn then.@@reverands571
All life on this planet ceases when the earths core cools enough for the magnetosphere to collapse in any case. Period. That VERY certain doomsday only humans have the capacity to help life survive or outlive.
People fought over wearing masks! They won't change their destructive ways any time soon. We are destined to fail this.
You are explaining how unprecedented the rate of warming is, but you're not really explaining what that means. Ecosystems and species can usually adapt to an extent to changing climate, over millions of years. Not over the short time frames we're seeing. Evolution is just not nimble enough. It's too slow for the job. And certainly not in the context of the globe spanning sidelining of the natural world we've achieved. In many cases reasonably natural areas that remain are completely isolated. Species will not even be able to migrate as they would have to migrate through humanity's territories. And even looking at massive biomes like the Amazon rainforest. It's currently staggering under the effects of climate change. Most of it could be gone in 10-20 years. Replaced by savannah and desert. Not all, but most of it. And that's a scary, scary thing to contemplate. Let alone be responsible for.
And also... It's all good and well to talk about 2100 to try to look at a timeframe that people might relate to (we should be so lucky - that people would be so considerate), but fact is we're on a trajectory right now where by 2100 a lot of the proudest works of humanity will be gone along the coasts of the world. But, beyond 2100 it looks way, way worse if appropriate action is not taken. Incredibly so.
People really, really need to understand that we're at a point where unprecedented, radical action is needed to stave off the worst. Which is not by 2100, but by 2300 and beyond. Or these few current generations will be loathed in history as utter imbeciles, fools, delinquent and possibly even evil. All of us. Around the world.
question 1: Are sea levels rising? 2. what is the cause of the rise?
Absolute sea level (as measured from the middle of the ocean) has risen four inches since 1993, according to NASA, and its rate of rise has doubled since then, according to the World Meteorological Organiztaion. Global warming from a build-up of CO2 in the atmosphere is melting the icecaps, which is increasing the volume of the oceans. As that water warms, it also expands, increasing volume even further.
When ice melts that gets into the ocean/seas, overall salinity is lowered. It's a fact the the lower the salinity, the lower density yet the larger volume. Melting of sea ice doesn’t increase the mass but it increases the volume and therefore causes the water level to rise, but that is not the only cause of sea rise.
1. Yes
2. Melting ice and thermal expansion.
Land-based ice melting into the oceans. Primary areas are Antartica and Greenland.
I know that today's weather is just a fraction of the Earth's History, but there are noticeable climate changes happening right now. You can definitely see that Global Warming is happening here in Northeastern Minnesota! We have ZERO Snow on the ground & the temperature has been about 20 degrees above average (in the 40°F's) & even our current lows are higher than our average high temperature. It's been raining here since Saturday - my grass is greener now than it was all summer! We have had a couple snowless Christmases since 1972. Because we have been in a drought for a few summers (they don't necessarily categorize it as a drought during winter months) & Duluth is about 16 inches below normal for snow & we've been breaking or close to breaking records for warmest November, December, daily temperature, high low temperature, etc. We've had some cold temperatures & we've had an inch or two of snow multiple times this winter season & it melted quickly each time, but nothing like a traditional winter. We will close out the year above freezing & we traditionally would have a very cold January (by fairly cold, I mean -40°F windchill & almost that cold air temperature the entire month of January). Last January & most of last winter was a rollercoaster of cold & warm temperatures. It worries me when our weather isn't cold & snowy in winter!
Ever thought of El Nino?
Same thing happened 150 years ago. CIimate change played no role then nor now.
@@glidercoach then when it repeats every year you say it a cycle. How funny!
Be prepare for the chaos.
The average global is warmer, but not for each region, not every moment.
I once encountered a spring +20C for 2 months, then it falled to -1C just one week, while usually it should be 5-15C.
I remember when Trump said about historic cold in Texas. He didn't count that instead of well-defined -50C arctic, it broke into several -20C pieces to many regions in low altitude.
So oh yeah, the average increased, but unbearable cold to some regions.
@@nvkhoi1
It's not happening every year.
Indeed, für Earth was cooling since 4000 BCE. Climax in the little Ice age. This makes the breakout more striking.
The only way we can buffer That rate is S.A.I. while getting the necessary reductions that are a must implemented especially by those who have made massive fortunes on the business of burning carbon. I do like Thunderf00t's video on the Faustian Deal our "betters" signed the dotted line decades ago condemning our great grandchildren to their (now our) legacy.
What will be the apocalypse generation be called? Pandemeration? Flooderation?
Thanks for keeping us updated!!
To put the climate back to it's stable condition might require more than just stopping current input (carbon output). To settle down the melting at the poles might require another ice age first. Whoever comes after us will also have to deal with all of the environmentally toxic element we have unleashed - metals, plastic, and manufactured chemicals. Before that, we will have to survive the temperature overshoot that is now evident. People's behavior won't change until it is forced, I believe.
We are in an ice age...
@@old-pete glaciers and polar ice is melting - disappearing.
