"The United Nation’s Intergovernmental Panel on Climate Change (IPCC) claims that the only way they can get their computerized climate models to produce the observed warming is with anthropogenic (human-caused) pollution. But they’re not going to find something if they don’t search for it. More than one scientist has asked me, “What else COULD it be?” Well, the answer to that takes a little digging… and as I show, one doesn’t have to dig very far."  Roy W. Spence, PhD
