Climate Unit: The Politics

I'm interested in focusing on the Politics of Climate because I want to know why it is such a decisive topic in the United States and whether this phenomena occurs world wide. I'm a lover of debates and open discussions and I'd like to see what other people think about climate and why they think it is such a controversial issue. It's very interesting to see what other people have to say about the issue and what other, new ideas they bring to the table especially with Climate being such a large topic of interest right now in the world, like the summit just held in Paris over climate change.
