To be fair, all that is really required for human extinction is for us to start firing our nukes. Geopolitically destabilizing events increase the potential for that considerably.

That's not in any way to say that climate change must necessarily lead to thermonuclear war or anything so dramatic as that, but human extinction is a real threat hanging over our heads at all times. It's something worth being worried about.

Just remembered, he was basing this on the planet being uninhabitable soon.

I find that laughable. Despite how quickly and how chaotically the climate changes, we are not going to go extinct because earth is becoming uninhabitable
