AFAIK, they don't know why the Mass Extinction happened (and there're still debates about that meteor as well)

Even just the possibility

is enough to scare me, frankly. It's like Russian roulette - I don't need to *know* with absolute certainty that there is a bullet in the chamber to know that pulling the trigger is a really bad idea.

But even if we escape a repeat of the Permian-Triassic mass extinction, six degrees of warming still means a breakdown of civilisation (and a mass extinction of both human and other life on a *slightly* less extreme level). And while that is not even remotely as bad as a wiping out of nearly all higher life forms on the planet, it's bad enough that I neither want to be around to see it happen, nor know that the next generation or the one after that will see it happen.

Wow, we're pretty much screwed, especially the ice caps.

Well, we *may* be screwed.

Important distinction, because this means we may still be able to do something about it.
