A lot of people died 8000 years ago as well.
Anybody who says that the Earth has been this hot before and survived is technically correct, but they should look at this map and consider the implications:

This is not a minor inconvenience for some people if we do nothing. This is avoidable disaster that we are ignoring.
- radford-neal 4y agoThe late cretaceous was a lot longer than 8000 years ago. Lots of people did die 8000 years ago (of course!). It was also the time when important agricultural plants were being domesticated and civilization was beginning - probably because the climate was nice, allowing that to happen, when it hadn't for the previous 200,000 years of Homo sapiens' history.
- jandrese 4y agoWe have already blown past the CO2 levels of the Holocene maximum, so looking back to it as a stopping point isn't helpful. The Cretaceous had CO2 levels around 1000ppm so we aren't there yet. We are currently at around 418ppm and rising about 2ppm per year (but that rate is increasing). If we don't change our ways soon this scenario becomes increasingly likely. Also, there is an alternate theory that Humans finally developed agriculture because the climate change had made their previous hunter-gatherer lifestyle untenable and they were forced to improvise. Many species of animal died out.
