I think they were more driven by biological evolution than by climate change, though. At least some of them (Cambrian, maybe also Dinosaurs).

Humans are actually very adaptable to all sorts of climates. They've lived in the arctic and in the Saharah.

Also, mass extinction events OK, but we are talking about a runaway effect of heating up the atmosphere, turning it into a Venus like planet. That doesn't seem to have happened before.

A Saharah like climate won't feed 7.5 billion people. If the population crashes to a few million stragglers living mostly at the poles then we'll regress back to the stone age.

There may be no way yet to support 7,5 billion people on renewable energy. Then what?

Also not saying everything will become like the Saharah. Just that humans may adapt better than those animals who died in mass extinction events in the past.

Lived? Yes. Thrived? Not so much.
