S. Fred Singer, former director of the U.S. Weather Satellite Service and University of Virginia professor emeritus commented about these sorry circumstances stating in part:

"Many would place the beginning of the global warming hoax on the Senate testimony delivered by James Hansen of NASA [director of the Goddard Institute for Space Studies] during the summer of 1988. More than anything else, this exhibition of hyped alarm triggered my active skepticism about the man-made global warming scare. This skepticism was amplified when I acted as reviewer of the first three IPCC reports, in 1990, 1996, and 2001. Increasingly claims were made for which there was no evidence; in some cases the 'evidence' was clearly manufactured. For example, the 1966 report used selective data and doctored graphs. It also featured changes in the text that were made after the scientists had approved it and before it was printed."
