Climate change is, apparently, passé.  Democratic politicians are avoiding the topic and dialing back ambitious plans to reduce emissions.  The President apparently doesn’t think it exists, and the government’s official position is that its effects are too uncertain to worry about. Denial isn’t the world’s best coping mechanism, but it works, at least temporarily.  The problem is that, while sometimes that lump you were worried about does go away, sometimes it keep growing and getting harder to treat. In the end, reality doesn’t much care whether you believe in it.
