Move over Al! It seems more and more prominent scientists are beginning to trade in their alarmism for skepticism regarding the whole contentious, man-made Global Warming issue. It should be interesting to see what happens when more of them defect to the 'other side' of the GW "we're gonna fry" doomsday scenario. Many of these scientists are doing so at risk to their careers and reputations. Defectors are never kindly looked upon, so it could get nasty, particularly when there is so much at stake for those who have invested so much in 'climate hysteria'.
The U.S. Senate Committee on Environment & Public Works (EPW) has compiled a list of scientists who have recently changed positions regarding the man-made Global Warming argument. It's by no means a comprehensive list, and there are other scientists not yet listed, but I have added snippets from some of those scientists that are listed, below. For more comprehensive information and a full list of scientists, go to EPW.
Geophysicist Dr. Claude Allegre, a top geophysicist and French Socialist who has authored more than 100 scientific articles, written 11 books and received numerous scientific awards, converted from climate alarmist to skeptic in 2006. Allegre, who was one of the first scientists to sound global warming fears 20 years ago, now says the cause of climate change is "unknown" and accused the “prophets of doom of global warming” of being motivated by money, noting that "the ecology of helpless protesting has become a very lucrative business for some people!"
Geologist Bruno Wiskel of the University of Alberta was once such a big believer in man-made global warming that he set out to build a “Kyoto house” in honor of the UN sanctioned Kyoto Protocol which was signed in 1997. Instead, he said he realized global warming theory was full of holes and ‘red flags,’ and became convinced that humans are not responsible for rising temperatures. Noting that the Earth has been warming for 18,000 years, Wiskel told the Canadian newspaper, “If this happened once and we were the cause of it, that would be cause for concern. But glaciers have been coming and going for billions of years." Wiskel also said that global warming has gone "from a science to a religion” and noted that research money is being funneled into promoting climate alarmism instead of funding areas he considers more worthy.
Astrophysicist Dr. Nir Shaviv, one of Israel's top young award winning scientists, recanted his belief that manmade emissions were driving climate change. "Like many others, I was personally sure that CO2 is the bad culprit in the story of global warming. But after carefully digging into the evidence, I realized that things are far more complicated than the story sold to us by many climate scientists or the stories regurgitated by the media. In fact, there is much more than meets the eye.” According to Shaviv, the C02 temperature link is only “incriminating circumstantial evidence. Solar activity can explain a large part of the 20th-century global warming...it is unlikely that [the solar climate link] does not exist.”
Botanist Dr. David Bellamy, a famed UK environmental campaigner, former lecturer at Durham University and host of a popular UK TV series on wildlife, recently converted into a skeptic after reviewing the science and now calls global warming fears "poppycock." According to a May 15, 2005 article in the UK Sunday Times, Bellamy said “global warming is largely a natural phenomenon. The world is wasting stupendous amounts of money on trying to fix something that can’t be fixed. The climate-change people have no proof for their claims. They have computer models which do not prove anything.”
Climate scientist Dr. Chris de Freitas of The University of Auckland, N.Z., also converted from a believer in man-made global warming to a skeptic. “At first I accepted that increases in human caused additions of carbon dioxide and methane in the atmosphere would trigger changes in water vapor etc. and lead to dangerous ‘global warming,’ But with time and with the results of research, I formed the view that, although it makes for a good story, it is unlikely that the man-made changes are drivers of significant climate variation.”
Meteorologist Dr. Reid Bryson, the founding chairman of the Department of Meteorology at University of Wisconsin (now the Department of Oceanic and Atmospheric Sciences, was pivotal in promoting the coming ice age scare of the 1970’s ( See Time Magazine’s 1974 article “Another Ice Age” citing Bryson: & see Newsweek’s 1975 article “The Cooling World” citing Bryson) has now converted into a leading global warming skeptic. In February 8, 2007 Bryson dismissed what he terms "sky is falling" man-made global warming fears. “Before there were enough people to make any difference at all, two million years ago, nobody was changing the climate, yet the climate was changing, okay?” Bryson told the May 2007 issue of Energy Cooperative News. “All this argument is the temperature going up or not, it’s absurd. Of course it’s going up. It has gone up since the early 1800s, before the Industrial Revolution, because we’re coming out of the Little Ice Age, not because we’re putting more carbon dioxide into the air,” Bryson said. “You can go outside and spit and have the same effect as doubling carbon dioxide,”
Global warming author and economist Hans H.J. Labohm was one of the 60 scientists who wrote an April 6, 2006 letter urging withdrawal of Kyoto to Canadian prime minister Stephen Harper which stated in part, “’Climate change is real’ is a meaningless phrase used repeatedly by activists to convince the public that a climate catastrophe is looming and humanity is the cause. Neither of these fears is justified. Global climate changes all the time due to natural causes and the human impact still remains impossible to distinguish from this natural ‘noise.’”
Paleoclimatologist Dr. Ian D. Clark, professor of the Department of Earth Sciences at University of Ottawa, reversed his views on man-made climate change after further examining the evidence. “I used to agree with these dramatic warnings of climate disaster. I taught my students that most of the increase in temperature of the past century was due to human contribution of C02...... However, a few years ago, I decided to look more closely at the science and it astonished me. In fact there is no evidence of humans being the cause. There is, however, overwhelming evidence of natural causes such as changes in the output of the sun. This has completely reversed my views on the Kyoto protocol.”
