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.

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.

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. From the Lamont-Doherty Earth Observatory of Columbia University web site (2003). Lamont-Doherty Earth Observatory of Columbia University The Earth Institute at Columbia University Open quote. 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.

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.

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."

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.

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.

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.

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.

Once it starts melting in earnest it's a rapid runaway effect. Even a rise to 3 degrees could lead to 85% of the permafrost melting.

I think there are two major factors in Earth's wildly changing climate: 1) plate tectonics, which changes the shape of the continents and also ends up affecting ocean currents (the current location of our continents actually encourage more ocean current flow to moderate temperatures) and 2) the Milankovitch cycle of changes to the Earth's orbit around the Sun, which may have resulted in major changes in the the climate due to changes in the eccentricity of Earth's orbit around the Sun, the polar axis tilt and polar axis precession. That's why the idea of an "iceball Earth" is potentially valid due to the changes I mentioned.

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.

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.

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.

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.

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!

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!

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.

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.

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.

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!*

Modern temperature records didn't begin until around the year 1880, which is when standardized temperature gauges began to be installed. Before that, scientists have to rely on other sources such as tree rings and ice cores to estimate past temperatures. When standard gauges (such as in Stevenson Screens) were installed, it began in the United States and the United Kingdom and then Europe. From what I could gather, they were installed on the periphery of other continents. I have no idea where all these temperature gauges are located today, nor have I been able to determine when they were installed. Not only that, I have seen several studies that many of the gauges don't operate properly, and that some them, due to urban sprawl, are located in or near urban heat islands, which means they record elevated temperatures, whereas in the past when they were located away from cities, they recorded lower temperatures. I have watched a huge amount of mainstream and independent news reports about climate, and I have yet to see one of them report on what I have just discussed. In my opinion, what we are hearing about temperatures is simply an educated guess, not hard scientific facts. Hey, PBS, why don’t you look into this?
@bcwbcw3741
@bcwbcw3741 4 месяца назад
Note that ice cores are taken not to study the ice but the gas isotope ratios of the air trapped in the highly compressed ice. The ratios are a measure of the average atmospheric temperature from when the ice was formed. Tree ring data is useful mostly for the more recent period the last ten thousand years or so which is also the duration of human civilization. Plant temperature zones are a better long term temperature measure as plants tend to be highly specialized to particular temperature ranges. The USDA had to recently update its planting zone charts for the US because of global warming with the shift about 300 miles every ten years. For the last thousand years or so there is also very good data for specific locations from Church and Chinese state first/last freeze, river and lake melt/freeze and growing season records. The heat island question has been heavily studied, just google it.

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.

Excellent point near the end there: can humans as a species actually adapt to the climate change that is happening right now, the changes that will continue even if we were to stop burning all fossil fuels this instant? And the hard answer is - maybe as a SPECIES. Not as a civilization. It's entirely possible that the human population could be decimated - between fire and flood, collapsing infrastructure, failed crops and the following famines, and the inevitable wars that would erupt over dwindling resources. It's a very ugly possibility, and one that is entirely avoidable. IF. If we get off our butts and do all that we can, right now, to bring in every speck of renewable energy that we can build, to wean ourselves and the machinery of our civilization away from fossil fuels... If the greater portion of humans who AREN'T filthy rich finally stand up to the corporations, the boards, the billionaires, and make ourselves clear: stop profiting off our suffering, off the destruction of our world. Because right now it really looks a lot like those mega rich people, groups, companies - and the governments that pander to them - are the only ones who'll survive. I dunno about anyone else, but I'm sure not okay with that outcome.

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.

Because the going up two degrees that has happened in the past couple hundred years is so ridiculously fast compared to the other time differentials on that chart that there's no way to even visually compare it effectively.

The problem is that the rate of warming today is so rapid that plants and animals cannot migrate, adapt and evolve rapidly enough. Since humans have been, are and always will be totally dependent upon the functional heath and capacity of our ecological life-support system for our own heath and survival, and since wild plants and animals can’t just run into an AC room to avoid a protracted heat wave, my prediction is that it will take active participation of humans in the for of genetic engineering, ecological restoration and enhancement to adapt to the coming greenhouse Earth. I expect that this job and other geoengineering jobs will be the top and the highest paying jobs of the coming century. I further predict that the necessity for action and the wealth that these people will accumulate will force society to acknowledge ecological literacy as literacy, to acknowledge that humans are part of the ecosystem, stimulate the development of ecologically-based and ecologically-constrained technology and the creation of an ecologically-based and ecologically-constrained economy. This will of course not occur without a fight as many will see the exodus and evacuation of uninhabitable areas of the planet as an opportunity to mine such areas for their mineral wealth with robots.

Thus they realize that they are to act as keystone species, stewards and resources to their world, leaving it to their progeny in a better state to than when they received it from their parents. Second, to propagate their species and its ecologically-based life-support system throughout the universe where alien species has not already done so. As their culture, economy and technology is ecologically-based and ecologically-constrained, growth within the sustainable bubble of their civilization is possible only through enhancing ecosystem functional capacity. Third, to protect and defend that bubble of life from all hazards and threats, arising from both within and from without, that would seek to harm and destroy it. THAT'S ALL! The Universe is a high pass filter that selects for the ethical species. That is it's purpose. Obey the mandates and your species will have eternal life and evolve into a moral creature. Disobey and your species will suffer the eternal death of extinction. No gods need be evoked to punish or save. We do it to ourselves!
