indeed, the vast right-wing conspirators show themselves.
I reviewed the list from my state, and found the name of an orthodontist that I know, who has political aspirations of running for the U.S. Senate. He has no credible background in climatology.
When the list is pared down, there are only 154 signators who have backgrounds in atmospheric science or climatology out of the 31,000 total. Just because you have an advanced degree doesn't necessarily make you an expert in global warming. Conversely, I am sure there are some without any college degrees who have read everything written on the subject and have become, in essence, self-made experts in climatology and global warming.
