The military's job is the security of America and it's allies; And to that end they are of course going to be VERY interested in Climate Change. Especially due to the fact that so many of the current hotspots of the world are going to be harmed the most by the changing climate. And geopolitics that is at the best of times a mixture of dry tinder and rocket fuel, is just gonna be made so much worse as storms strengthen, droughts lengthen, and people get hungry and angry.
