Massive disaster can be a huge distance from human extinction. A 1% die off is a massive disaster but even a 99% megadeath is 75 million people short of killing us all. I haven't seen any likely AGW scenarios that get us close to that. Maybe someone could point me that way.

- hirundo 7y agoHere's a credible paper asserting that the net feedback is negative: https://www.tandfonline.com/doi/full/10.1080/16000870.2019.1699387 https://www.tandfonline.com/doi/full/10.1080/16000870.2019.1... I'd have to know a lot more before deciding that either a runaway greenhouse or net cooling is plausible, let alone likely.
