Except not at all? I’ve not seen any climate predictions saying the surface of earth will be a denuded hellscape, but only civilization will be destroyed. Humans will not be wiped out, they’ll just be living way worse. Resources will be challenging but will exist. Many will die, but not all. Biological life will shift massively but will exist.

A grey mush turns us into a surface like mercury, completely and utterly consumed.

Even in the worst climate predictions modern presenting societies will live.
