Many former believers in catastrophic the man-made global warming myth have recently reversed themselves and are now global warming skeptics. The short list below is just the tip of the iceburg:Those who once believed in Global Warming and now do NOT:
Geophysicist Dr. Claude Allegre
, a top geophysicist and French Socialist who has authored more than 100 scientific articles.
Geologist Bruno Wiskel
of the University of Alberta. "Wiskel 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."
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."
Mathematician & engineer Dr. David Evans
, who did carbon accounting for the Australian Government, recently detailed his conversion to a skeptic. “I devoted six years to carbon accounting, building models for the Australian government to estimate carbon emissions from land use change and forestry. When I started that job in 1999 the evidence that carbon emissions caused global warming seemed pretty conclusive, but since then new evidence has weakened the case that carbon emissions are the main cause. I am now skeptical.”
Climate researcher Dr. Tad Murty
, former Senior Research Scientist for Fisheries and Oceans in Canada, also reversed himself from believer in man-made climate change to a skeptic. “I stated with a firm belief about global warming, until I started working on it myself.”
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.”
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.
Global warming author and economist Hans H.J. Labohm started out as a man-made global warming believer but he later switched his view after conducting climate research. Labohm wrote on August 19, 2006, “I started as a anthropogenic global warming believer, then I read the [UN’s IPCC] Summary for Policymakers and the research of prominent skeptics.” “After that, I changed my mind.”
Paleoclimatologist Tim Patterson, of Carlton University in Ottawa converted from believer in C02 driving the climate change to a skeptic. “I taught my students that CO2 was the prime driver of climate change,” Patterson wrote on April 30, 2007. Patterson said his “conversion” happened following his research on “the nature of paleo-commercial fish populations in the NE Pacific.”
Physicist Dr. Zbigniew Jaworowski, chairman of the Central Laboratory for the United Nations Scientific Committee on the Effects of Radiological Protection in Warsaw, took a scientific journey from a believer of man-made climate change in the form of global cooling in the 1970’s all the way to converting to a skeptic of current predictions of catastrophic man-made global warming.
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. The association seemed so clear and simple. Increases of greenhouse gases were driving us towards a climate catastrophe,” Clark said in a 2005 documentary "Climate Catastrophe Cancelled: What You're Not Being Told About the Science of Climate Change.” “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,” Clark explained.
Environmental geochemist Dr. Jan Veizer, professor emeritus of University of Ottawa, converted from believer to skeptic after conducting scientific studies of climate history. “I simply accepted the (global warming) theory as given,” Veizer wrote on April 30, 2007 about predictions that increasing C02 in the atmosphere was leading to a climate catastrophe. “The final conversion came when I realized that the solar/cosmic ray connection gave far more consistent picture with climate, over many time scales, than did the CO2 scenario.”
MIT Scientist Richard Lindzen and former UN IPCC reviewer, called fears of man-made global warming ‘silly’ in January 2007 and equated concerns to ‘little kids’ attempting to "scare each other."
Canadian climatologist Timothy Ball recently called fears of man-made global warming "the greatest deception in the history of science."
Panel of Broadcast Meteorologists Reject Man-Made Global Warming Fears in February 2007 - Claim 95% of Weathermen Skeptical "You tell me you’re going to predict climate change based on 100 years of data for a rock that’s 6 billion years old?" Meteorologist Mark Johnson said. "I’m not sure which is more arrogant — to say we caused (global warming) or that we can fix it," Meteorologist Mark Nolan said.
60 prominent scientists wrote the Canadian Prime Minister in 2006 saying that "If, back in the mid-1990s, we knew what we know today about climate, Kyoto would almost certainly not exist, because we would have concluded it was not necessary."
Meteorologist James Spann said in January that he does "not know of a single TV meteorologist who buys into the man-made global warming hype" and he noted that "Billions of dollars of grant money is flowing into the pockets of those on the man-made global warming bandwagon."
Kentucky meteorologist Chris Allen said in February 2007, "All of this (alarmism) is designed to get your money and then guilt you in to how you live your life."
Bernie Rayno, senior meteorologist with AccuWeather said in February 2007, "Our climate has been changing since the dawn of time. There is not enough evidence to link global warming to greenhouse gases."
India’s Glaciologists and Geologists stepped forward to reject climate alarmism in February 2007. They included VK Raina, a leading glaciologist in India, RK Ganjoo, the director of the Regional Centre for Field Operations and Research on Himalayan Glaciology and geologist MN Koul. "Claims of global warming causing glacial melt in the Himalayas are based on wrong assumptions," Raina told the Hindustan Times
Paleoclimatologist Labels Climate Fears Oversimplified. Boston College’s professor of geology and geophysics Amy Frappier explained in February 2007, "The geologic record shows that many millions of years ago, CO2 levels were indeed higher - in some cases many times higher - than today." Frappier noted that greenhouse gas concentrations in the atmosphere do not consistently continue to have a warming effect on Earth, but gases instead stabilize in the atmosphere and cease having a warming effect. "At some point the heat-trapping capacity of [the gas] and its effect get saturated," said Frappier, "and you don't have increased heating."
Chinese Scientists Say C02 Impact on Warming May Be ‘Excessively exaggerated’ – Scientists L. Zhen-Shan, and S. Xian’s 2007 study noted that "Although the CO2 greenhouse effect on global climate change is unsuspicious, it could have been excessively exaggerated." Their study concluded that "it is high time to reconsider the trend of global climate change "looked at "multi-scale analysis of global temperature changes" and concluded "that "global climate will be cooling down in the next 20 years."
Climate scientist Henrik Svensmark released a report in February 2007 with researchers at the Danish National Space Centre which shows that the planet is experiencing a natural period of low cloud cover due to fewer cosmic rays entering the atmosphere. "We have the highest solar activity we have had in at least 1,000 years," Svensmark said.
Dr Habibullo Abdussamatov, Head of Space Research, Pulkovo Observatory, in Russia said in January 2007. "It is no secret that increased solar irradiance warms Earth's oceans, which then triggers the emission of large amounts of carbon dioxide into the atmosphere. So the common view that man's industrial activity is a deciding factor in global warming has emerged from a misinterpretation of cause and effect relations," Abdussamatov said.
Climate Scientist Fred Singer & Environmental Economist Dennis Avery’s 2006 book: "Unstoppable Global Warming: Every 1500 Years" details the solar-climate link using studies from peer reviewed literature and "shows the earth’s temperatures following variations in solar intensity through centuries of sunspot records, and finds cycles of sun-linked isotopes in ice and tree rings."
Niger Calder, former editor of New Scientist, also expressed his view last week that the UN rejects science it sees as "politically incorrect" and the UN denies that "climate history and related archeology give solid support to the solar hypothesis."
"Mars Melt Hints at Solar, Not Human, Cause for Warming, Scientist Says," according to a February 2007 article in National Geographic. The article explained: "Habibullo Abdussamatov, head of the St. Petersburg's Pulkovo Astronomical Observatory in Russia, says the Mars warming data is evidence that the current global warming on Earth is being caused by changes in the sun. ‘The long-term increase in solar irradiance is heating both Earth and Mars,’ Abdussamatov said.’"
French President Jacques Chirac: "Kyoto represents the first component of an authentic global governance" Ah-HA!!
