The Skeptical Environmentalist
The Skeptical Environmentalist is a book written by Bjorn Lomborg, a professor of statistics from Aarhus University. He was a greenie who believed that the environment was being endangered by human activities. When he looked at the statistics he found that many things were getting better rather than worse.
He therefore wrote his book to tell the world and came in for heavy criticism. The Scientific American, a well known magazine devoted eleven pages to denigrating him. They stopped just short of saying that he was wrong.
