I think about Global warming usually a couple times a day on average. what helps me cope is thinking "Won't it be interesting?". whether we overcome it or not, both futures are going to really fascinating. We're going to learn so much. even the self-made extinction of the only known intelligent life in the universe would be a very important event to witness, and might have implications for the Fermi paradox and so on. it's got to be kind of satisfying too, like getting the final season to a show, opposed to all the people who died in the previous centuries, that were like watching until it was cancelled by the network.
