We have nightmares because our brain is running simulations to put us in jeopardy to see what we'll do or to acclimatize us to that idea that something bad could happen. It's just how human beings are wired because the entire time we were evolving we had to jump quick or the leopard would get us or whatever it was. It's Darwinian.

People of conscience in our leadership in Washington have been scared off by the right and the fossil fuel lobbies. They won't even use the term "sustainability" or "climate change" in an energy bill, which is ludicrous on its face. It completely ignores the elephant in the room that we're all dealing with. The average American doesn't even believe climate change is real, they think it's all a hoax.
