These issues cannot be addressed out of context. The context is the runaway corporatization going on today around the world. Corporations are heavily invested in the military industrial complex and so powerful that there is very little left in the way of national sovereignty---and I am not just speaking of the U.S. To try to address issues of climate change without addressing the underlying financial machines that run roughshod over attempts at democracy is to fail to solve the problem. This problem is researched and presented very cogently by Naomi Klein in her book, "The Shock Doctrine," which I think everyone should read to gain an understanding of the real forces behind the difficulties we are facing in this age.
