I think we're past the point of "if" it is happening. The biggest concern is why this is a political debate. The issue of climate change isn't a conservative vs liberal viewpoint, it's a conservative vs. scientist debate. It's clear to see that the Koch brothers (and the like, even those who are invested in oil themselves) are responsible for this way of thinking but what really bothers me is how people who watch Fox News, I mean those around me, friends and even some of my own family, still believe this is not happening because of what dumbfucks like Ted Cruz tell them. It's infuriating.
