When 97% of the world's scientists agree about the problem, that we've been able to measure quite accurately the amount of C02 in the air at staggering levels and when greedy bastards like Disney's CEO got out of Trump gov for this retraction, I think that we can easily say that yes, climate change is a PROBLEM and it would be about time for the denial-ers to get their fact straights and to evaluate the consequences for the species (including ours) VERY seriously.

Trump is as idiot as he is ignorant. At least, there is a glimpse of sun: on a procedural level, the US can't pull out before 2020 and Trump is quite likely to not get reelected.
