Five more scientists have been added to the over 400 scientists in the Minority Senate Report who dispute man-made global warming claims:
1. Physics professor Dr. Frederick Wolf of Keene State College in New Hampshire has taught meteorology and climatology courses for the past 25 years and will be undertaking a sabbatical project on global warming. Wolf recently declared he was skeptical of man-made climate fears. “Several things have contributed to my skepticism about global warming being due to human causes. We all know that the atmosphere is a very complicated system. Also, after studying climate, I am aware that there are cycles of warm and cold periods of varying lengths which are still not completely understood,” Wolf wrote EPW on January 10, 2008. “Also, many, many of the supporters (or believers) of human induced warming have not read the IPCC report AND Al Gore is NOT a climate scientist!” Wolf added. He also rejected the claim that most scientists agree mankind is driving a “climate crisis.” “I am impressed by the number of scientific colleagues who are naturally skeptical about the conclusion of human induced warming,” Wolf added.
2. Biologist Dr. Matthew Cronin, a research professor at the School of Natural Resources and Agricultural Sciences at the University of Alaska Fairbanks, called predictions that future global warming would devastate polar bear populations “one extreme case hypothesis.” “We don’t know what the future ice conditions will be, as there is apparently considerable uncertainty in the sea ice models regarding the timing and extent of sea ice loss. Also, polar bear populations are generally healthy and have increased worldwide over the last few decades,” Cronin said in March 2007. “Recent declines in sea ice and indications that polar bears in some areas may be negatively impacted are cause for concern, but in my opinion do not warrant designation of the species as threatened with extinction,” Cronin said. “I believe that consideration of multiple hypotheses regarding the future of sea ice and polar bear populations would provide better science than reliance on one extreme case hypothesis of loss of sea ice and associated drastic declines in polar bear populations,” Cronin said.
3. Senior Meteorologist Dr. Wolfgang P. Thuene was a former analyst and forecaster for the German Weather Service in the field of synoptic meteorology and also worked for the German Environmental Protection Agency. Thuene currently works in the Ministry of Environment and Forests of Rheinland-Pfalz. In 2007, Thuene rejected the idea that mankind is driving global warming. “All temperature and weather observations indicate that the earth isn’t like a greenhouse and that there is in reality no ‘natural greenhouse effect’ which could warm up the earth by its own emitted energy and cause by re-emission a ‘global warming effect’. With or without atmosphere every body looses heat, gets inevitably colder. This natural fact, formulated by Sir Isaac Newton in his ‘cooling law’, led Sir James Dewar to the construction of the ‘Dewar flask’ to minimize heat losses from a vessel. But the most perfect thermos flask can’t avoid that the hot coffee really gets cold. The hypothesis of a natural and a man-made ‘greenhouse effect’, like eugenics, belongs to the category ‘scientific errors,” Thuene wrote on February 24, 2007.
“The infrared thermography is a smoking gun proof that the IPCC-hypothesis cannot be right. The atmosphere does not act like the glass of a greenhouse which primarily hinders the convection! The atmosphere has an open radiation window between 8 and 14 microns and is therefore transparent to infrared heat from the earth’s surface. This window cannot be closed by the distinctive absorption lines of CO2 at 4.3 and 15 microns. Because the atmosphere is not directly heated by the Sun but indirectly by the surface the earth loses warmth also by conduction with the air and much more effectively by vertical convection of the air to a very great part by evaporation and transpiration. Nearly thirty percent of the solar energy is used for evaporation and distributed as latent energy through the atmosphere,” Thuene wrote. “Summarizing we can say: Earth’s surface gains heat from the Sun, is warmed up and loses heat by infrared radiation. While the input of heat by solar radiation is restricted to the daytime hours, the outgoing terrestrial radiation is a nonstop process during day and night and depends only on the body temperature and the emissivity. Therefore after sunset the earth continuous to radiate and therefore cools off. Because the air is in physical contact with the ground it also cools off, the vertical temperature profile changes, and we get a so called surface inversion which inhibits convection,” Thuene explained.
4. Chemist and Nuclear Engineer Robert DeFayette was formerly with NASA’s Plum Brook Reactor in Ohio and the Nuclear Regulatory Commission (NRC) at its headquarters office near Washington, DC. DeFayette, who earned a masters degree in Physical Chemistry, also worked at the NRC’s Regional Office near Chicago where he was a Director of the Enforcement staff. He also served as a consultant to the Department of Energy. DeFayette wrote a critique of former Vice President Al Gore’s book, An Inconvenient Truth, in 2007. “I freely admit I am a skeptic,” DeFayette told EPW on January 15, 2008. “I take umbrage in so-called ‘experts’ using data without checking their sources. My scientific background taught me to question things that do not appear to be right (e.g.-if it sounds too good to be true, it probably is). That is one reason I went to such detail in critiquing Gore’s book. I also strongly object to the IPCC and its use of so-called ‘experts,’” DeFayette explained.
In his March 14, 2007 critique of Gore, DeFayette dismissed Gore’s claim that “the survival of our civilization” is at stake. DeFayette wrote, “Nonsense! Civilization may one day cease to exist but it won’t be from global warming caused by CO2. I can think of many more promising scenarios such as disease, nuclear war; volcanic eruptions; ice ages; meteor impacts; solar heating.” DeFayette asserted that Gore’s book was “a political, not scientific, book. There is absolutely no discussion about the world’s climate history, effects of the sun, other planets, precession, eccentricity, etc.” DeFayette disputed Gore’s notion of a “consensus.” “Until a few months ago, scientists believed we had 9 planets, but now we have 8 because Pluto was demoted. In the 1600s scientists believed we lived in an earth-centered universe but Galileo disagreed and proved we lived in a sun-centered universe. At the time of Columbus, the scientific consensus was that the earth was flat but obviously that was wrong. In the late 18th century, ‘Neptunists’ were convinced that all of the rocks of the Earth’s crust had been precipitated from water and Robert Jameson, a British geologist, characterized the supporting evidence as ‘incontrovertible,’” DeFayette wrote. “In each of these cases there was ‘scientific consensus’ that eventually was rejected,” he added.
5. Nuclear Physicist and Chemical Engineer Dr. Philip Lloyd, a UN IPCC co-coordinating lead author on the Technical Report on Carbon Capture & Storage, was in charge of South Africa’s Chamber of Mines’ Metallurgy Laboratory and was a former professor at University of Witwatersrand where he established a course in environmental chemical engineering. Lloyd has served as President of the South African Institution of Chemical Engineers, the Federation of Societies of Professional Engineers, and the Associated Scientific and Technical Societies of Southern Africa. Lloyd, who has authored over 150 refereed publications, currently serves as an honorary research fellow with the Energy Research Centre at the University of Cape Town.
Lloyd rejects man-made climate fears. “I have grave difficulties in finding any but the most circumstantial evidence for any human impact on the climate,” Lloyd wrote to EPW on January 18, 2008. “The quantity of CO2 we produce is insignificant in terms of the natural circulation between air, water and soil. I have tried numerous tests for radiative effects, and all have failed. I have tried to develop an isotopic method for identifying stable C12 (from fossil fuels) and merely ended up understanding the difference between the major plant chemistries and their differing ability to use the different isotopes. I have studied the ice core record, in detail, and am concerned that those who claim to have a model of our climate future haven’t a clue about the forces driving our climate past,” Lloyd wrote. “I am particularly concerned that the rigor of science seems to have been sacrificed on an altar of fundraising. I am doing a detailed assessment of the IPCC reports and the Summaries for Policy Makers, identifying the way in which the Summaries have distorted the science. I have found examples of a Summary saying precisely the opposite of what the scientists said,” he concluded.
