I think I have written about this before, but when I was at the Cornell College of Agriculture in 1969-1970 they were talking about global warming and the greenhouse effect from carbon dioxide. It was generally accepted there, and they were in departments like agronomy, meteorology and plant breeding. They were people who were in favor of the Vietnam war, thought organic farming was a joke, and were generally conservative pro-military people who had probably never been in a room where gay marriage was discussed. More than anything, they really were scientists and felt that ideas should be held to the test of empirical data. It is not that hard to show a correlation and always hard to show cause and effect.
