The link you mention is in the first sentence and refers to "all but ruled out most of the worst-case scenarios". [0] The second sentence, about "a good chance that we can hold warming below the 2 degree level" links to a different tweet, with different data [1]. I don't think there's any risk of "civilization ending" below 4 or 5 degrees. In the future, before calling someone "relentlessly stupid", you probably should check whether you've understood correctly what they're saying. But this is the sort of emotionally charged rhetoric that happens when people are primed for the apocalypse! That's why doomerism is a problem! It's cathartic, but not helpful.
