Last year I saw an episode of Sesame Street that was dedicated to explaining the scientific process. The character chosen was Oscar the Grouch, you know the guy living in the garbage can. He did a song and dance routine where he spelled out the process in three parts. Observe, Record, and Annoy!. It was a wonderful expression of how the truth, once discovered, has to be spread around even if it ruffles feathers. Joe you can't cherry pick your science any more than you can cherry pick your data. Astronomy is part of physics which is the basis of chemistry and the foundation of meteorology. The same method that gave us the HR diagram leads us to human caused global warming. And Rush Limbaugh is not a scientist, his opinions on the matter mean nothing. I'm amazed how people think they can be involved in astronomy but firmly reject global warming, evolution, inflationary cosmology, cigarettes causing cancer, or leaded gasoline causing brain damage in kids. To me these guys are not astronomers or even just involved in astronomy. They are just guys with big expensive toys and narrow minded opinions. DT
