The following is a joke.
Recent work that I have just done has uncovered a new, important connection between politics and climate in the US. It appears that whenever the US is unusually dry over a large area, either at the same time or not long afterward, Democrats gain more power in the Senate. This has implications for Global Warming. If warming causes drought to become more widespread, Democrats will surely enter a period of dominance in the Senate. Even a wacko denier like me finds this a frightening prospect. On the other hand, if droughts become less widespread, Democrats will probably have difficulty attaining and maintaining majorities in the Senate. This prospect is surely much more desirable, and even implies a positive feedback, as Republicans are a well known leading cause of Global Warming. Of course, I imagine that environmentalists find that possibility to be disturbing.
