Humans haven't lived on the planet on geological timescales. All of human civilization only became possible because 10k years ago the climate cooled and stabilized enough for there to be agriculture. Without agriculture there is no human civilization, no nation states, no institutions. We go back to being hunter gathers. With an unstable climate agriculture disappears. Billions will dies, life expediencies will crater, the modern world you know will no longer exist. Yes, the planet will be fine, at one point it was a giant snowball, humans are fucked.

> Humans haven't lived on the planet on geological timescales. All of human civilization only became possible because 10k years ago the climate cooled and stabilized enough for there to be agriculture. The average global temperature in the Jurassic era was 16.5C, which is 2.5C higher than the current average global temperature. Average CO2 levels in the atmosphere were as high as 2000 ppm. The planet was teeming with life, an abundance of flora and fauna. While dinosaurs were the apex predators, mammals flourished as well. > Without agriculture there is no human civilization, no nation states, no institutions. We go back to being hunter gathers. Since the first part is false, the second part is moot. It also supposes we would have trouble adapting whereas humans are ingenious at finding ways to survive. > With an unstable climate agriculture disappears. Billions will dies, life expediencies will crater, the modern world you know will no longer exist. See previous argument. > Yes, the planet will be fine, at one point it was a giant snowball, humans are fucked. Yet here we are. Our ancestors survived the Ice Age. Their distant ancestors survived the Jurassic era. My bet is on humans.

  CO2 was at that level with an entire planet covered in a healthy ecosystem. If that happened now, we would probably witness the entire global collapse of the ecology. It took hundreds of millions of years to cool down that much, and we’ve turned it back up in a century. Animals (humans included) do not have the time to adapt. Have you ever been in a stuffy meeting where brain fog sets in or you start to feel tired? That’s around 2k ppm where that sets in. Humans don’t like that much co2. No offense, but your argument doesn’t seem thought through.
