A physician should be able to understand the basic climate issues. A lot of physicians do. People with many different backgrounds work in this field, not just climatologists. The most prominent one is the Great Global Warming Guru Dr. James Hansen who recently retired from NASA/GISS. He is an astrophysicist like I am and comes from the astrophysics group at the University of Iowa. I’m from the competing group at the University of Chicago.
Michael Crichton stated: “Personally, I don’t worry about the nation. But I do worry about science.” This is the central problem for science. How do we keep the ignorant from practicing when their knowledge is purely political and their zeal is pseudo-religious.
