Well there was a time -- and not too long ago -- when the world warmed more than any human has ever seen.

    If only there was an organism on earth that consumed excess CO2 and let put oxygen. We could put these things everywhere. 🤔🤔🤔

    the title of this video should be: when Greenland was green

    Fighting global warming to save the rainforests sounds oddly counterproductive now.

    Ahh come on guys don't worry about it, we are just one supervolcano away from becoming extinct and the planet gets a new type of life form

    What's important to keep in mind is that a quantitative difference in the rate of change can mean a qualitative difference in the effect of that change. E.g. if the change is slow enough for a species to adapt, it adapts. If it's faster than it can adapt, the species is gone. Which in turn might cause other species to go extinct, even if they could've otherwise adapted.

    I agree with you, 56 million years ago is not long ago.

    yes we are still in an iceage, but iceages only make up %25 of earths climate history, a more normal/average earth climate is co2 in the thousands and zero year round ice at the poles.

    How about a timeline between Ice Ages, sea levels, warm periods, the homo species, forests and desertification, super volcanoes and their relationships ending with current global warming.

    The earths history is so amazing and vast. Even if you spent every second of your life studying it you woudnt even get close to knowing it all.

    Basic cable news should be swapped for Eons, that would be fantastic.

    Republicans were driving SUV's and causing global warming 56 million years ago?!?! They are even more diabolical than previously realized.

    I just want to point out that the Eocene maximum was not the same baseline we are dealing with in today's Holocene maximum( the narrator mentioned this as well). So comparisons of emissions and radiative forcing only go so far in informing projections.

    I just want to say that I am a fossil collector and hunter and (you can see in my profile) I have found huge Palm fronds from the Paleocene Eocene Thermal Maximum event as far north as British Columbia Canada.

    "..the climate began to cool..." The Ice Ages are death events through freezing. Long live CO2!

    I wonder what it was like in the rainforests at the poles during the long night of winter.

    Maybe some crazy ancient industry let its pollution get out of control, humanoid of some species
