Read Judith Curry's interview on NPR.org.
DR. WILLIAM HAPPER: Award-winning Princeton Professor of Physics, former Director of Energy Research at the Department of Energy from 1990 to 1993, author of over 200 published scientific papers, and a fellow of the American Physical Society, the American Association for the Advancement of Science, and the National Academy of Sciences.
Happer was reportedly fired by former Vice President Al Gore in 1993 for failing to adhere to Gore’s scientific views. In 2009 he testified before Congress about CO2 levels:
“Many people don’t realize that over geological time, we’re really in a CO2 famine now. Almost never has CO2 levels been as low as it has been in the Holocene (geologic epoch) – 280 (parts per million - ppm) – that’s unheard of. Most of the time [CO2 levels] have been at least 1000 (ppm) and it’s been quite higher than that."
“I keep hearing about the ‘pollutant CO2,’ or about ‘poisoning the atmosphere’ with CO2, or about minimizing our ‘carbon footprint.’ This brings to mind another Orwellian pronouncement that is worth pondering: ‘But if thought corrupts language, language can also corrupt thought.’ CO2 is not a pollutant and it is not a poison and we should not corrupt the English language by depriving ‘pollutant’ and ‘poison’ of their original meaning." (Emphasis added.)
Most recently, in January of 2014, in an exclusive interview with Climate Depot, Happer spoke out against the notion being popularized by the media that the extremely cold winter weather conditions and polar vortex were the result of man-made climate change saying, "Polar vortices have been around forever. They have almost nothing to do with more CO2 in the atmosphere.”
LARRY BELL: professor and endowed professor at the University of Houston where he founded and directs the Sasakawa International Center for Space Architecture and heads the graduate program in space architecture.
This picture is far different from the really scary “climate crisis” reports we constantly receive in the media. And this circumstance isn’t the first time prominent news producers, supported by “scientific experts”, have warned about impending doom. An October 7, 1912 Los Angeles Times feature proclaimed “Fifth Ice Age is on the Way: Human Race Will Have to Fight for Existence in Cold”. By August 9, 1923 the situation had become desperate, prompting the Chicago Tribune to declare “Scientists Say Arctic Ice Will Wipe Out Canada”. Then, after a short period when the world appeared to be warming again, the March 1, 1975 cover of Science News magazine depicted New York City being swallowed by a glacier. The New York Times followed with a headline story “Scientists Ponder Why World’s Climate is Changing: A Major Cooling Widely Considered to be Inevitable”. The prestigious National Academy of Sciences agreed: global cooling was a real threat.
