That wasn’t meant to be a wild worst case scenario. That’s a middle case scenario as far as I’m concerned, I understand that there are many natural feedback loops that we are triggering now, the Earth is on track to become largely uninhabitable.
To humans.
But it’s hard for me to believe in some kind of extinction of all complex life in the biosphere. The Earth could warm 8°C and be within the its historical range that can and has supported complex life in the past. It will be a cataclysmic transition, most megafauna will probably die, but there are many species alive today that actually were alive when the Earth was that much warmer.
