Stephen Walt and Matthew Yglesias both have smart posts on looking at climate change through a national security lens. Possibly one of the worst outcomes of our failure to address climate change (and other attendant issues like peak oil) would be to lock ourselves into a zero-sum, conflict-based position with the rest of the world. This is truly a kind of dystopian scenario, with rich and powerful nations crushing poor ones under their collective boot in order to maintain a stranglehold on scarce resources, treating refugees as threats rather than as human beings in need, and insulating ourselves in our own relative prosperity against the misery of the rest of the world.

I mean, more than we already do.
