Congrats on 10k Adam, thoroughly well deserved! If you ever fancy exploring paleoclimatology in more detail, your resident geologist here would be happy to help!
This video was great to put our current situation in historical context to counter the skeptics who say how this is just a part of the earth's natural cycles and not all due to human impacts. I read somewhere that the current concentration of CO2 in the atmosphere is the highest it's been in 20 million years...is that right? I've also wondered about the effects of volcanic eruptions and meteorite impacts on CO2 and global temperature in the past. I'd give you a few thousand more likes if I could but they only let you hit that button once!
Adam is a fraud. His claim that the medieval warm period was different because it wasn't global is a lie. It still contributed to global average temperatures. There are plenty of places on earth that are cooler than the long term averages. He doesn't explain why temperatures rose even though CO2 ppm remained low. What caused the warming 13,000 years ago and the cooling again during the younger dryas period and the warming again if CO2 remained steady? This is why Adam is on UA-cam and not taken seriously in the scientific community.
So happy that I discovered this channel, I was looking for a way to be up to date with climate issues and even if I appreciate social media and newsletters, you make those serious issues super engaging and instructive. Thank you for your work!
I’m a political activist, and climate change is truly the most daunting danger humanity has ever faced. If I had to choose between being an “undesirable” in Nazi Germany and being a human living anywhere on earth in fifty years, I’d have to pause and really consider my response. Whatever your beliefs on karma, living systems seek homeostasis, and when imbalance reigns, the inevitable motion toward balance is inevitable. It’s not a punishment, it’s simply an adjustment.
Amazing video! I was already in awe of your editing skills, now I need to add skateboarding skills to that! But seriously, this is one of the best climate change explained videos I've ever seen, I will for sure be sharing. And by the way you'd need at least ten million subscribers before you have to worry about maybe being overrated.
I like the analogy anthropogenic activity is equivalent to the CO2 emissions of ~125 volcanoes erupting 24/7. Seems like pretty easy numbers to calculate but I haven’t seen them.
Brilliant video! Thank you for continuing to make them! Cool moves by the way! I bet you're amazing on a skateboard haha. I think we can all learn from earths past and we can all learn from past mistakes. Very important lessons in looking back! Congratulations to you on your many subscribers, I hope more come soon!! 😊 Keep on informing the world, you wonderful person 😋
was lucky enough to meet Randall Monroe a few years back, and immediately brought up exactly the same comic with him! having it scroll vertically (as he did) _really_ emphasised the scale of today's changes
I wish the temperature graph had a Y axis with numbers on it. It made me wonder: How much is the recent spike in temperature in actual degrees? He said that the fluctuations prior to modern times were a fraction of a degree so does that mean that the spike at the end is a maybe a few degrees? Or is it much greater?
Irrelevant; CO2 levels will rise from their current levels. Btw, the majority of sea level rise is not from land ice melting, but from thermal expansion as sea temperatures rise.
I like and appreciate your videos, you make things much easier to understand, and when my partner gets on the denial bandwagon i can roll my eyes knowing he doesnt know what he is taking about... your channel is still underrated. your subs may have doubled in a year , but i watch a crochet channel that got to 20,000 subs in a few months... what does that say about how difficult it is to get the message about climate change out there?!
I don't know much about this but does co2 not help stuff to grow like trees and stuff I am really interested in this also great channel I will be a new subscriber
welcome to the channel! plants love carbon-dioxide it's true. but plants don't love extreme weather, like heatwaves, floods and droughts, all of which are already becoming more frequent and severe (heatwaves everywhere, floods and droughts in certain specific places). what's more, specific types of forests grow in specific climates. those climates are shifting North every year we heat up the planet, and forests simply can't move as fast as those shifts require. soooo it's absolutely true to say co2 is great for plants if everything else stays the same. but unfortunately - thanks to co2's effects on the climate - everything is *not* staying the same.
Thank you for your inspiring videos. I'm 65 now and I've never driven a car, I don't have a family, don't eat meat often, don't fly and do as much as possible to keep my carbon footprint small. Yet I feel guilty for what the world is about to face. I'm so sorry.
I really think that we should feel that kind of individual responsibility for a problem that is so structural in its nature. Let's push to hold those with power responsible instead.
Nicely done. and well said. But the issues go so much deeper. And I'm glad to give examples. My ADULT kids, who are eager to tell me how we are all doomed, will go to sleep with the air conditioner on, then get cold, so turn their heater blankets on. Will then leave the house leaving both running. My ADULT kids never turn off lights. My ADULT kids get new Phones pretty much every time a new one comes out even though the old one was almost the same. This goes for laptops, computers, Xboxes, Playstations, Switches. They buy them all! My ADULT kids buy and throw away clothes like you have no idea. My ADULT kids get Uber eats instead of cooking. My ADULT kids consume, consume, consume. This is a huge problem. I am 52 and have had 5 mobile phone since I was around 22 years old. How many phone have you had? This is what is causing climate change. The fix. Ban phones, social media, computers.. Well thats a start. Then we need to get rid of the BIG offenders. ROADS and ROOF TOPS! Yes.. You see, roads and roof tops on houses build up and bounce back huge amounts of heat into the atmosphere. So clearly, we need to reduce the amount of roads and houses. Which would be great, because then kids wouldn't need phones to text while they are driving to their freinds houses, as they couldn't drive, as there would be no roads, and their friends wouldn't have houses anyway because house need roofs. So I'm really glad you are trying to do something, but I think it's about time, and maybe would not be popular for your chanel, to point out, that it's the UNDER 30's that is the real issue here. We have been yelling at you guys to turn the lights OFF for the last THIRTY YEARS! So before you have a go at me.... Because I really care about our home planet.. How many mobile phones have you had?
Want a little constructive advice, Adam? You think of yourself as a popularizer, or something like that. A science communicator? Whatever the label, here's what you need: Ditch the gimmicks. If it doesn't support what you have to say, in some way, leave it out. Anything else just looks sophomoric.
Yes and no! Global food webs in the aftermath of the asteroid impact did collapse in the span of days to years. However, the main kill mechanisms were darkness (so no photosynthesis!), cooling and acidification due to the impact-related debris and aerosols released to the atmosphere. This means the mass extinction really had not much to do with global warming. The current climate change due to greenhouse gas emissions to the atmosphere is actually unprecedented in the geological record. The rate of release of CO2, for example, is 10 times faster than any other event in Earth’s history, including the Permian mass extinction (the largest our planet has ever experienced), or the slightly more recent hyperthermals, like the PETM.
Very interesting question, and the honest answer is... I'm not sure. Certainly I agree with e dominguez that there are few historical analogues of where we're headed, and basically none for the speed at which we're headed there.
What about time periods in earth history where the average global temperatures were much higher with much more CO2 in the atmosphere. Without humans to cause it. Even then there has always been some kind of glaciation event to drive the earth back into another ice age. Commet strikes and or Super Volcanoes as I understand it. Surely Anthropomorphic climate change is a major moden driver for increased global temperatures. However, the earth systems do not seem as fragile as they are being made out to be. Higher Temps do not necessarily mean exactly bad, I think the threshold for what is good and bad may be wider than were lead to believe. Look, I've got Solar Pannels and a Turbo Diesel and I'm no climate denier. Just looking for insight. Great video by the way.
From an ecosystem standpoint, the rate of change is the issue. The current changes being driven by reintroducing CO2 into the atmosphere that had been sequestered for millions of years is extremely abrupt. As far as temperatures and CO2 levels being higher in the past, that is true. Those levels and temperatures would feel oppressive to humans. We did not evolve in a high temperature, high CO2 environment. None of our food crops thrive in those extremes either. People claiming the earth is dying or some such are wrong. But species are going extinct at an alarming rate that will accelerate. Weather patterns that millions of people, more likely billions, rely on will be disrupted. We are making the future shittier for existing species, including ourselves.
"Correlation does not indication causation." *sigh* Well, yeah, but often misleading. For instance, a hypothesis which claims sunspots or something else are responsible for the correlation of CO2 with temperature needs to explain why they are correlated. The most plausible counterfactual is that CO2 emissions lag temperatures. They have in some of the paleoclimate times in the past, but *not* *this* *time*. Also, there are other, more sophisticated ways of treating causality (Granger, Convergent Cross Mapping) which indicate that, yes, indeed, CO2 increases ARE causing the warming. And, as to WHERE the CO2 is coming from, one or more of Climate Adam's excellent videos have explained that, too. (Hint: Isotopic chemistry of excess CO2.)
Another strong indication of where the excess CO₂ comes from is the fact that the rate of increase in the atmosphere is only about _half_ of our emissions, meaning that the nature (oceans & vegetation) must be absorbing the other half. If the nature itself was a _net_ source of CO₂, the surplus would be _added_ to our emissions. The resulting rate of increase in the atmosphere would be at least _twice_ as high as actually measured, that is, at least 5 ppm/year rather than 2.4 ppm over the last decade.
yes, this is all definitely true! as I often say to people: "if you think increasing the warming gas _isn't_ causing the world to warm you need to explain 1) why not; and 2) what mysterious other thing is since all other possible sources don't even correlate."

Adam makes good points, and leans into the supportable data. However the attribution insinuations are laughable. As well, omission of certain inconvenient facts help to paint an alarming picture. Can we talk about deforestation without talking about global greening and re-wilding? Is it responsible to insinuate negative impacts without citing positive impacts due to anthropogenic Co2 forcing? I live on the prairies, everyone here knows we're living at the bottom of a dried up lake bed. And while surface temperatures are certainly rising, there were far hotter perdiods in the Holocene.
Would be great to take a look deeper into Earth's past... Guess I'll need to get some more subscribers!

Aww I'm on the way to become a paleoclimatologist myself and this video meant so much to me!! 😍 Congratulations and keep up the good work Adam!
Awesome! It's such an interesting and important field... Feels almost like detective work.

Will you do a 50,000 years of climate when you hit 50K subscribers? Ice age ocean bed oxygen isotope research is fascinating!
CONGRATUALATIONS ON THE 10,000! Question is, what will be the interevent time for the NEXT 10,000? That will be indicative.
Almost there now

So by how much sea levels going to raise with current CO2 level?
Irrelevant; CO2 levels will rise from their current levels. Btw, the majority of sea level rise is not from land ice melting, but from thermal expansion as sea temperatures rise.
