I'm talking about political groupings in the U.S. The left clearly does much better on climate change. (That probably applies to other wealthy democratic countries, where Green parties are common.)

I'm not sure how the countries mentioned are involved, or even what their political leanings are in this context. Iran is a highly conservative authoritarian theocracy, North Korea a totalitarian dictatorship that is nominally communist. What does that have to do with climate change?
