In an excellent article published February 5 at the Canada Free Press website, Dr. Timothy Ball, a doctor of climatology and Chairman of the Natural Resources Stewardship Project, wrote that "Believe it or not, Global Warming is not due to human contribution of Carbon Dioxide (CO2). This in fact is the greatest deception in the history of science. We are wasting time, energy and trillions of dollars while creating unnecessary fear and consternation over an issue with no scientific justification."

The guy's a climate scientist, a doctor of climatology. He is certainly a worthy source.
