Crichton graduated summa cum laude from Harvard College, received his MD from Harvard Medical School, and was a postdoctoral fellow at the Salk Institute for Biological Studies, researching public policy with Jacob Bronowski. He taught courses in anthropology at Cambridge University and writing at MIT. Crichton\'s 2004 bestseller, State of Fear, acknowledged the world was growing warmer, but challenged extreme anthropogenic warming scenarios. He predicted future warming at 0.8 degrees C. (His conclusions have been widely misstated.)
