Republicans didn't even wait for a global climate change deal to be struck in Paris to start undermining it.

Last month, congressional Republicans were loudly discouraging other nations from signing onto any agreement, arguing that the US won't keep up its end of the bargain if a Republican wins the 2016 presidential election.
