This is the the professional description of physicist Harold Lewis:
Emeritus Professor of Physics, University of California, Santa Barbara, former Chairman; Former member Defense Science Board, chmn of Technology panel; Chairman DSB study on Nuclear Winter; Former member Advisory Committee on Reactor Safeguards; Former member, President's Nuclear Safety Oversight Committee; Chairman APS study on Nuclear Reactor Safety Chairman Risk Assessment Review Group; Co-founder and former Chairman of JASON; Former member USAF Scientific Advisory Board
On October 6, 2010, Harold Lewis resigned his membership in the American Physical Society (APS), a membership he had maintained for sixty-seven years. His reason? The APS position on climate change/global warming, and the way funding has forced or coerced scientists into endorsing the manmade global warming theory. In his letter to APS president Curtis Callan, Lewis wrote the following passage:
"It is of course, the global warming scam, with the (literally) trillions of dollars driving it, that has corrupted so many scientists, and has carried APS before it like a rogue wave. It is the greatest and most successful pseudoscientific fraud I have seen in my long life as a physicist. Anyone who has the faintest doubt that this is so should force himself to read the ClimateGate documents, which lay it bare. (Montford's book organizes the facts very well.) I don't believe that any real physicist, nay scientist, can read that stuff without revulsion."
In it's response to Lewis's charges, the APS denied that, as an organization, it benefits financially. They also said that the society maintains the highest ethical standards because, well, it maintains the highest ethical standards.
