Seriously, what the hell?
Sea levels *are* rising. The agricultural productivity of various areas *is* changing. Droughts *are* becoming more common. Debate the causes of these things all you want, but these things are happening, and they *will* have implications for the national security of basically every nation on the planet.
Preventing the Pentagon and the CIA from researching climate change is asinine. If we’re not prepared to deal with these things, we’re screwed. When we intervene in a conflict caused by these things, and given the hawks infesting both parties we will intervene, we’ll go in with a plan that has less connection to reality than we’ve ever had, and we’ll be looking at a best case scenario of wasting resources to no effect.
