I heard the latest ice age was rough too

  Oh, for sure. A sudden ice age would definitely ruin global civilization. But that's not the issue, and the opposite of an ice age, a rapid period of warming with huge disruptions to ecosystems, is not good either. It's almost like huge disruptions to ecosystems is the problem and independent from the red team/blue team political polarization culture-war horseshit.

    No it is not much about the rate of disruption, the end state we are aiming at will be painful and not much would adapt even if it would be 1000 years?! That it happens so quickly within one generation and is caused by us is icing on top.. It seems we had 5 mass extinction events on earth so far, one caused by an asteroid, and the 4 others by climate change. Sure, something will survive, regrow or be newly created.. if we go for 4°C expectations for earth to recover on its own to something similar we had now are just another 30 million years ;)

      > No it is not much about the rate of disruption I believe it is. The rate at which iso-climate lines are moving north is faster than a lot of species can move. Most fauna could be ok by that criteria alone, but most flora can't move so rapidly (a lot of tree species can only move 10m/10years). And when the flora goes, a lot fauna does too. Sure, the human species will survive. It certainly did with a few million of individuals for most of the time. But I believe we're already in the 6th mass extinction event, perhaps the biggest so far. We're going to get a lesson from nature. The only question is how tough will it be. I believe large famines, wars, and a partial civilization collapse are coming.
