Nah, this is just doom and gloom based on persistent and pervasive messaging. On large geological timescales, our temperatures are pretty close to the mean. Even given the last 500 million years, we're nowhere near the peak [1]. Will habitable zones change? Yes. Will migrations occur? Yes. Will there be unrest leading to disease, famine and death? Yes, for sure. And we could get all those things from war, a major natural disaster or an extraterrestrial event. Just take war for example. War promises to bring all of those changes too, that hasn't stopped human beings from fighting. If anything, destroying our economies to deal with the climate threat will inevitably lead to war, and then the resulting outcome will be the same: Death, famine, unrest, change/loss of habitable zones. What would we have gained? [1] https://www.climate.gov/media/11332 https://www.climate.gov/media/11332

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.

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.

    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.
