It's also "not impossible" that a meteorite wipes us all out tomorrow. Which serious scientist is predicting a K-T level extinction event?
Serious predictions are talking about a couple of degrees over thousands of years. That's not out of the ordinary in terms of variance for life on earth right now. Sure, some species may have to migrate, some will go extinct one way or another, but not a K-T level event.

That's very different. It may be hard to separate the climate change extinctions from the regular habitat destructions that are already ongoing, though.
