While many believe there is an overwhelming scientific consensus supporting the theory of man-made global warming, a petition circulated by the Oregon Institute of Science and Medicine has, in recent years, garnered the names of some 31,000 scientists and other experts who disagree with this notion. Comments petition organizer, Dr. Arthur Robinson: “The purpose of this is to demonstrate that there is no scientific consensus in favor of human-caused global warming, and in fact, if there is a consensus, it is in the opposite direction. Between 10 and 15 times as many Ph.D.’s in the physical sciences have signed this petition as participate in the United Nations process, and the United Nations scientists have not signed anything.”
