I predict it'll be worse than that, there'll be so much suffering across the planet that it'll suffice as an ample distraction for folks. Water conflicts, illegal border crossings, a billion or two climate refugees... we won't have time to think about who caused climate change, we'll be chasing who caused whatever specific recent catastrophe until we're at 3c and everything's on fire. The fact that nobody's really identified the Arab spring and Syrian civil war as being climate change related just reinforces that point.The really unfortunate part is that, IF things get really bad, by the time it's REALLY OBVIOUS to even the most staunch denialist that it's so, most of them will be dead. Those not dead will have had plenty to time to work on blaming it somehow on "the media" and illegals. In true Karl Rove fashion, they'll proudly proclaim that THEY were the ones fighting climate change all along and the Democrats were the ones causing it.
