That's odd, because I seem to recall several of the evangelical groups endorsing the whole global warming fight. They are also very much in favor of stem cell research, just not necessarily embryonic stem cell research. As we all know (at least I hope WE do), adult stem cell research has made vast gains over the last several years, even more so than embryonic research.
Somehow, I tend to doubt whether or not you actually comprehend what being an evangelical truly means. You seem to have some confusion in that respect. The only folks who don't believe in evolution of some fashion are the hard fundamentalists. They shouldn't be confused with evangelicals.
