Maybe we should change the wording: from "climate change" to "extinction horizon"
@dbat Nah, we're not going to go extinct.
Probably millions of us will survive.

@yora @dbat

Presuming "us" includes insects.

@Infrogmation @dbat No. Humans are stupidly durable. To make humans go entirely extinct, you would have to annihilate the entire biosphere.
As long as daytime temperatures at the poles don't regularly exceed 40 degrees, some humans will hang on.
