Here is a comment I just posted. Some of the discussions can become quite heated, so beware.
Peter
WeatherRusty,
Thanks for your honest and sincere attempt to answer my question about why there are so many global warming skeptics among meteorologists. And I knew you were a meteorologist. But I also wonder about so many other skeptical scientists who study other aspects of the Earth and the universe and understand the scientific process. What they see is the radical alarmism, the blatant phony hypocrisy of people like Al Gore, John Kerry, Nancy Pelosi and other what are called "limousine liberals".
All these other scientists know a great deal about science. They may not know the computer codes for the climate models that seem to be kept so secret, but secrecy and exaggeration have no place in science. That is salesmanship and politics. They see through the hype and it makes them skeptical and suspicious. Scientists are trained to be questioning and doubting.
For example, I recently asked a geologist acquaintance if he was "skeptical" of man-caused global warming. Take my word for it if you will, but he is one of the most experienced, well educated, and intelligent geologists, who are after all, "Earth Scientists" that I have known. He said he is "more than skeptical". He said he didn't believe a bit of it. The same holds true for every geologist I encounter and discuss this with.
And if you don't think these geologists don't know the "astoundingly simple" physics, or chemistry, or mathematics you talk about, I say you are wrong. In fact, I could make a case for many geologists knowing more and having a far more realistic grasp of Earth's climate changes than any so-called computer-modeling "climatologist".
To listen to Al Gore on this issue is totally absurd. To have him testify before a Congressional Committee on this issue is ludicrous; to have our politicians, or anyone for that matter, take him seriously is dangerous; and to pass laws costing billions based on his ideas is insanity.

No Consensus About Causes of Global Warming
The results of this study are vastly different from those who continually say there is a "consensus" about the causes of global warming. We're being deceived. The question is why?

Causes of Climate Change Varied: Canadian Poll Show No Consensus
By Gordon Jaremko, edmontonjournal.com
Only about one in three Alberta earth scientists and engineers believe the culprit behind climate change has been identified, a new poll reported today. The expert jury is divided, with 26 per cent attributing global warming to human activity like burning fossil fuels and 27 per cent blaming other causes such as volcanoes, sunspots, earth crust movements and natural evolution of the planet. A 99-per-cent majority believes the climate is changing. But 45 per cent blame both human and natural influences, and 68 per cent disagree with the popular statement that “the debate on the scientific causes of recent climate change is settled.”
The divisions showed up in a canvass of more than 51,000 specialists licensed to practice the highly educated occupations by the Association of Professional Engineers, Geologists and Geophysicists of Alberta. “We’re not surprised at all,” APEGGA executive director Neil Windsor said today. “There is no clear consensus of scientists that we know of.”
The only agreement among professionals is “we should do everything we can” to understand climate, adapt structures such as buildings and bridges to change and reduce human contributions to harmful trends, Windsor said. The survey received 1,077 replies or a sample rated as an accurate portrait of the occupational groups’ views to within three percentage points 19 times out of 20, APEGGA reported. Alberta Environment helped design the poll and will give the results to the provincial government, association spokesman Philip Mulder said. APEGGA is planning an “environmental summit” with other concerned agencies on Alberta climate change causes, effects and adaptations.

More Scientists Skeptical of Man-Caused Global Warming Speak Out
There is a growing list of scientists expressing their skepticism over the presumption of man-caused global warming and climate change. As it becomes more politically acceptable to express doubt, I think this trend will continue.
Peter
Below are the latest scientists to be added to the over 400 scientists who dispute man-made global warming claims: (Marc Morano)
1. Chemist and Biochemist Dr. Michael F. Farona, an emeritus professor of chemistry at the University of Akron and the University of North Carolina at Greensboro, critiqued the news media for inadequate reporting about global warming and expressed climate skepticism. “Data, numbers, graphs, trends, etc., are generally missing in supposedly scientific reports on global warming. These articles are usually long on opinions and short on hard data. Phrases such as ‘scientists agree that ...’ scientists doubt that ...’ do not belong in a scientific article. There are more data in Michael Crichton's novel ‘State of Fear’ than in all the global warming articles combined that I have read,” Farona wrote on January 3, 2008.
“There have been at least four interglacial periods, where the glaciers have advanced and retreated. The last ice age ended about 10,000 years ago and, in the case of North America, left the Great Lakes in the glacier's retreat. The glaciers are still retreating, so there should not be any great surprise that the sea level is rising. The industrial revolution is about 150 years old, compared to 10,000 years of warming. Can human activities have really made a significant contribution to rising temperatures in that amount of time?” Farona asked.
“We know that the east coast of the U.S. was flooded during the previous interglacial period, so sea level rising and coastal flooding are not unique to this interglacial period. Why now the draconian predictions of coastal flooding as if this has not happened before?” he continued. “What is the relationship between an increased level of carbon dioxide and temperature? Can it be predicted that an increase of so many parts per billion of carbon dioxide will cause an increase of so many degrees? I have not seen any answers to the questions posed above, leading me to adopt a somewhat skeptical view of blaming global warming on human activities.
What puzzles me is the reluctance of climatologists to provide scientific data supporting their dire predictions of the near future if we don't change our ways,” Farona concluded.
2. Award winning meteorologist Brian Sussman, a member of the American Meteorological Society (AMS), former member of the AMS Education Advisory Committee, and formerly of KPIX-TV CBS in San Francisco, is the author of the forthcoming book “Global Whining: A Denier’s Handbook.” “Mankind's burning of fossil fuels is allegedly warming the planet. This hypothesis couldn't stand the test of an eighth grade science fair. And if you dare poke holes in the hypothesis you're branded a 'denier,’” Sussman told EPW on January 3, 2008. “Well fine. I'd rather be called a 'denier' than try to push a scheme that would make Karl Marx green with envy,” Sussman added.
3. Climate statistician Dr. William M. Briggs, who specializes in the statistics of forecast evaluation, serves on the American Meteorological Society's Probability and Statistics Committee and is an Associate Editor of Monthly Weather Review. Briggs, a visiting mathematics professor at Central Michigan University and a Biostatistician at New York Methodist Hospital, has a new paper coming out in the peer-reviewed Journal of Climate which finds that hurricanes have not increased number or intensity in the North Atlantic.
Briggs, who has authored numerous articles in meteorological and climatological journals, has also authored another study looking on tropical cyclones around the globe, and finds that they have not increased in number or intensity either. Briggs expressed skepticism about man-made global warming fears in 2007. "There is a lot of uncertainly among scientists about what's going on with the climate," Briggs wrote to EPW on December 28, 2007. "Most scientists just don't want the publicity one way or another. Generally, publicity is not good for one's academic career. Only, after reading [UN IPCC chairman] Pachauri's asinine comment [comparing scientists skeptical of man-made climate fears to] Flat Earthers, it's hard to remain quiet," Briggs explained.
"It is well known that weather forecasts, out to, say, four to five days, have skill; that is, they can beat just guessing the average. Forecasts with lead times greater than this have decreasing to no skill," Briggs wrote. "The skill of climate forecasts---global climate models---upon which the vast majority of global warming science is based are not well investigated, but what is known is that these models do not do a good job at reproducing past, known climates, nor at predicting future climates. The error associated with climate predictions is also much larger than that usually ascribed to them; meaning, of course, that people are far too sure of themselves and their models," he concluded.
4. Hydrologist and geologist Mike McConnell of the U.S. Forest Service is a professional Earth scientist who has studied atmospheric pollution, post-wildfire mitigation planning, and groundwater surface water modeling. In 2007, McConnell dissented from the view that mankind has created a climate crisis. “Climate change is a climate system that we have no real control over,” McConnell wrote on December 27, 2007. “Our understanding on the complexities of our climate system, the Earth itself and even the sun are still quite limited. Scaring people into submission is not the answer to get people to change their environmental ways,” McConnell explained. He also dismissed claims that the human race was “the cause of our global warming.”
McConnell wrote, “There is no real basis for this. There is a growing body of scientific literatures outlining that this not to be the case.” He concluded, “Now, if Earth was suffering under an accelerated greenhouse effect caused by human produced addition of CO2, the troposphere should heat up faster than the surface of the planet, but data collected from satellites and weather balloons do not support this fundamental presumption even though we are seeing higher CO2. We ought to see near lockstep temperature increments along with higher CO2 concentration over time, especially over the last several years. But we're not.”

Global Warming Scientist Paid by Heinz-Kerry
This is very interesting information. How do we know who to believe. Follow the money......
Peter
GeoPeter,
You made a statement about Dr. James Hansen receiving $250,000 in some form from a foundation run/financed by Heinz (Ketchup)Kerry. Can you document that? Nobody can hold a candle to the hypocrisy of the Kerrys. They make Al Gore look like a rank amateur.
http://www.giss.nasa.gov/research/news/20010305/
Dr. Jim Hansen, Chief of the Goddard Space Flight Center's Goddard Institute for Space Studies in New York, N.Y., and one of this year's recipients of a $250,000 Heinz Award, receives his award tonight at a ceremony at the Folger Shakespeare Library in Washington, D.C.
http://www.heinzawards.net/Heinz_mechanica.PDF
Dr. Hansen began his lifelong study of the Earth’s atmosphere in the 1970s at NASA’s Goddard Institute for Space Studies. It was Dr. Hansen’s interest that led the Goddard Institute to concentrate on global climate change.

If a climate skeptic receives any money from industry, the media immediately labels them and attempts to discredit their work. The same media completely ignore the money flow from the environmental lobby to climate alarmists like James Hansen and Michael Oppenheimer. (ie. Hansen received $250,000 from the Heinz Foundation and Oppenheimer is a paid partisan of Environmental Defense Fund) The alarmists have all of these advantages, yet they still feel the need to resort to desperation tactics to silence the skeptics.

List of global warming activists, now skeptics
Growing number of major scientific figures convert to skeptics after reviewing new research
Wednesday, May 16, 2007 By Marc Morano
Following the U.S. Senate's vote today on a global warming measure, there is a shift taking place in climate science. Many former believers in catastrophic man-made global warming have recently reversed themselves and are now climate skeptics. The names below are just a sampling of the prominent scientists who have spoken out recently to oppose the perceived alarmism of man-made global warming.
The media's climate fear factor seemingly grows louder even as the latest science grows less and less alarming by the day. It is also worth noting that the proponents of climate fears are increasingly attempting to suppress dissent by skeptics.
Once Believers, Now Skeptics
Geophysicist Dr. Claude Allegre, a top geophysicist and French Socialist who has authored more than 100 scientific articles and written 11 books and received numerous scientific awards including the Goldschmidt Medal from the Geochemical Society of the United States, 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!" “Glaciers’ chronicles or historical archives point to the fact that climate is a capricious phenomena. This fact is confirmed by mathematical meteorological theories. So, let us be cautious,” Allegre explained in a September 21, 2006 article in the French newspaper L'EXPRESS.
The National Post in Canada also profiled Allegre on March 2, 2007, noting “Allegre has the highest environmental credentials. The author of early environmental books, he fought successful battles to protect the ozone layer from CFCs and public health from lead pollution.” Allegre now calls fears of a climate disaster "simplistic and obscuring the true dangers” mocks "the greenhouse-gas fanatics whose proclamations consist in denouncing man's role on the climate without doing anything about it except organizing conferences and preparing protocols that become dead letters." Allegre, a member of both the French and U.S. Academy of Sciences, had previously expressed concern about manmade global warming. "By burning fossil fuels, man enhanced the concentration of carbon dioxide in the atmosphere which has raised the global mean temperature by half a degree in the last century," Allegre wrote 20 years ago. In addition, Allegre was one of 1500 scientists who signed a November 18, 1992 letter titled “World Scientists' Warning to Humanity” in which the scientists warned that global warming’s “potential risks are very great.”
Geologist Bruno Wiskel of the University of Alberta recently reversed his view of man-made climate change and instead became a global warming skeptic. 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. Wiskel wanted to prove that the Kyoto Protocol’s goals were achievable by people making small changes in their lives. But after further examining the science behind Kyoto, Wiskel reversed his scientific views completely and became such a strong skeptic, that he recently wrote a book titled “The Emperor's New Climate: Debunking the Myth of Global Warming.”
A November 15, 2006 Edmonton Sun article explains Wiskel’s conversion while building his “Kyoto house”: “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.” Wiskel now says “the truth has to start somewhere.” 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. "If you funnel money into things that can't be changed, the money is not going into the places that it is needed,” he said.
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,” Shaviv said in February 2, 2007 Canadian National Post article. 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" and "it is unlikely that [the solar climate link] does not exist,” Shaviv noted pointing to the impact cosmic- rays have on the atmosphere. According to the National Post, Shaviv believes that even a doubling of CO2 in the atmosphere by 2100 "will not dramatically increase the global temperature." “Even if we halved the CO2 output, and the CO2 increase by 2100 would be, say, a 50% increase relative to today instead of a doubled amount, the expected reduction in the rise of global temperature would be less than 0.5C. This is not significant,” Shaviv explained. Shaviv also wrote on August 18, 2006 that a colleague of his believed that “CO2 should have a large effect on climate” so “he set out to reconstruct the phanerozoic temperature. He wanted to find the CO2 signature in the data, but since there was none, he slowly had to change his views.”
Shaviv believes there will be more scientists converting to man-made global warming skepticism as they discover the dearth of evidence. “I think this is common to many of the scientists who think like us (that is, that CO2 is a secondary climate driver). Each one of us was working in his or her own niche. While working there, each one of us realized that things just don't add up to support the AGW (Anthropogenic Global Warming) picture. So many had to change their views,” he wrote.
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,” Evans wrote in an April 30, 2007 blog. “But after 2000 the evidence for carbon emissions gradually got weaker -- better temperature data for the last century, more detailed ice core data, then laboratory evidence that cosmic rays precipitate low clouds,” Evans wrote. “As Lord Keynes famously said, ‘When the facts change, I change my mind. What do you do, sir?’” he added.
Evans noted how he benefited from climate fears as a scientist. “And the political realm in turn fed money back into the scientific community. By the late 1990's, lots of jobs depended on the idea that carbon emissions caused global warming. Many of them were bureaucratic, but there were a lot of science jobs created too. I was on that gravy train, making a high wage in a science job that would not have existed if we didn't believe carbon emissions caused global warming. And so were lots of people around me; and there were international conferences full of such people. And we had political support, the ear of government, big budgets, and we felt fairly important and useful (well, I did anyway). It was great. We were working to save the planet! But starting in about 2000, the last three of the four pieces of evidence outlined above fell away or reversed,” Evans wrote. “The pre-2000 ice core data was the central evidence for believing that atmospheric carbon caused temperature increases. The new ice core data shows that past warmings were *not* initially caused by rises in atmospheric carbon, and says nothing about the strength of any amplification. This piece of evidence casts reasonable doubt that atmospheric carbon had any role in past warmings, while still allowing the possibility that it had a supporting role,” he added. “Unfortunately politics and science have become even more entangled. The science of global warming has become a partisan political issue, so positions become more entrenched. Politicians and the public prefer simple and less-nuanced messages. At the moment the political climate strongly supports carbon emissions as the cause of global warming, to the point of sometimes rubbishing or silencing critics,” he concluded.
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,” Murty explained on August 17, 2006. “I switched to the other side in the early 1990's when Fisheries and Oceans Canada asked me to prepare a position paper and I started to look into the problem seriously,” Murty explained. Murty 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, "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.”
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,” Bellamy added.
Bellamy’s conversion on global warming did not come without a sacrifice as several environmental groups have ended their association with him because of his views on climate change. The severing of relations came despite Bellamy’s long activism for green campaigns. The UK Times reported Bellamy “won respect from hardline environmentalists with his campaigns to save Britain’s peat bogs and other endangered habitats. In Tasmania he was arrested when he tried to prevent loggers cutting down a rainforest.”
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.” de Freitas wrote on August 17, 2006. “I accept there may be small changes. But I see the risk of anything serious to be minute,” he added. “One could reasonably argue that lack of evidence is not a good reason for complacency. But I believe the billions of dollars committed to GW research and lobbying for GW and for Kyoto treaties etc could be better spent on uncontroversial and very real environmental problems (such as air pollution, poor sanitation, provision of clean water and improved health services) that we know affect tens of millions of people,” de Freitas concluded.
de Freitas 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, “Significant [scientific] advances have been made since the [Kyoto] protocol was created, many of which are taking us away from a concern about increasing greenhouse gases.”
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. Bryson, was on the United Nations Global 500 Roll of Honor and was identified by the British Institute of Geographers as the most frequently cited climatologist in the world. “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,” he added. “We cannot say what part of that warming was due to mankind's addition of ‘greenhouse gases’ until we consider the other possible factors, such as aerosols. The aerosol content of the atmosphere was measured during the past century, but to my knowledge this data was never used. We can say that the question of anthropogenic modification of the climate is an important question -- too important to ignore. However, it has now become a media free-for-all and a political issue more than a scientific problem,” Bryson explained in 2005.
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,” Labohn explained. Labohn co-authored the 2004 book “Man-Made Global Warming: Unraveling a Dogma,” with chemical engineer Dick Thoenes who was the former chairman of the Royal Netherlands Chemical Society.
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 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.” “[My conversion from believer to climate skeptic] came about approximately 5-6 years ago when results began to come in from a major NSERC (Natural Sciences and Engineering Research Council of Canada) Strategic Project Grant where I was PI (principle investigator),” Patterson explained. “Over the course of about a year, I switched allegiances,” he wrote. “As the proxy results began to come in, we were astounded to find that paleoclimatic and paleoproductivity records were full of cycles that corresponded to various sun-spot cycles. About that time, [geochemist] Jan Veizer and others began to publish reasonable hypotheses as to how solar signals could be amplified and control climate,” Patterson noted.
Patterson says his conversion “probably cost me a lot of grant money. However, as a scientist I go where the science takes me and not were activists want me to go.” Patterson now asserts that more and more scientists are converting to climate skeptics. "When I go to a scientific meeting, there's lots of opinion out there, there's lots of discussion (about climate change). I was at the Geological Society of America meeting in Philadelphia in the fall and I would say that people with my opinion were probably in the majority,” Patterson told the Winnipeg Sun on February 13, 2007. Patterson, who believes the sun is responsible for the recent warm up of the Earth, ridiculed the environmentalists and the media for not reporting the truth.
"But if you listen to [Canadian environmental activist David] Suzuki and the media, it's like a tiger chasing its tail. They try to outdo each other and all the while proclaiming that the debate is over but it isn't -- come out to a scientific meeting sometime,” Patterson said. In a separate interview on April 26, 2007 with a Canadian newspaper, Patterson explained that the scientific proof favors skeptics. “I think the proof in the pudding, based on what (media and governments) are saying, (is) we're about three quarters of the way (to disaster) with the doubling of CO2 in the atmosphere," he said. “The world should be heating up like crazy by now, and it's not. The temperatures match very closely with the solar cycles."
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. “At the beginning of the 1970s I believed in man-made climate cooling, and therefore I started a study on the effects of industrial pollution on the global atmosphere, using glaciers as a history book on this pollution,” Dr. Jaworowski, wrote on August 17, 2006. “With the advent of man-made warming political correctness in the beginning of 1980s, I already had a lot of experience with polar and high altitude ice, and I have serious problems in accepting the reliability of ice core CO2 studies,” Jaworowski added.
Jaworowski, who has published many papers on climate with a focus on CO2 measurements in ice cores, also dismissed the UN IPCC summary and questioned what the actual level of C02 was in the atmosphere in a March 16, 2007 report in EIR science entitled “CO2: The Greatest Scientific Scandal of Our Time.” “We thus find ourselves in the situation that the entire theory of man-made global warming—with its repercussions in science, and its important consequences for politics and the global economy—is based on ice core studies that provided a false picture of the atmospheric CO2 levels,” Jaworowski wrote.
“For the past three decades, these well-known direct CO2 measurements, recently compiled and analyzed by Ernst-Georg Beck (Beck 2006a, Beck 2006b, Beck 2007), were completely ignored by climatologists—and not because they were wrong. Indeed, these measurements were made by several Nobel Prize winners, using the techniques that are standard textbook procedures in chemistry, biochemistry, botany, hygiene, medicine, nutrition, and ecology. The only reason for rejection was that these measurements did not fit the hypothesis of anthropogenic climatic warming. I regard this as perhaps the greatest scientific scandal of our time,” Jaworowski wrote. “The hypothesis, in vogue in the 1970s, stating that emissions of industrial dust will soon induce the new Ice Age, seem now to be a conceited anthropocentric exaggeration, bringing into discredit the science of that time. The same fate awaits the present,” he added.
Jaworowski believes that cosmic rays and solar activity are major drivers of the Earth’s climate. Jaworowski 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: "It may be many years yet before we properly understand the Earth's climate system. Nevertheless, significant advances have been made since the protocol was created, many of which are taking us away from a concern about increasing greenhouse gases."
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. “Actually, many other leading climate researchers also have serious concerns about the science underlying the [Kyoto] Protocol,” he added.
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,” Veizer wrote.
“It was the results of my work on past records, on geological time scales, that led me to realize the discrepancies with empirical observations. Trying to understand the background issues of modeling led to realization of the assumptions and uncertainties involved,” Veizer explained. “The past record strongly favors the solar/cosmic alternative as the principal climate driver,” he added.
Veizer acknowledgez the Earth has been warming and he believes in the scientific value of climate modeling. “The major point where I diverge from the IPCC scenario is my belief that it underestimates the role of natural variability by proclaiming CO2 to be the only reasonable source of additional energy in the planetary balance. Such additional energy is needed to drive the climate. The point is that most of the temperature, in both nature and models, arises from the greenhouse of water vapor (model language ‘positive water vapor feedback’,) Veizer wrote.
“Thus to get more temperature, more water vapor is needed. This is achieved by speeding up the water cycle by inputting more energy into the system,” he continued. “Note that it is not CO2 that is in the models but its presumed energy equivalent (model language ‘prescribed CO2’). Yet, the models (and climate) would generate a more or less similar outcome regardless where this additional energy is coming from. This is why the solar/cosmic connection is so strongly opposed, because it can influence the global energy budget which, in turn, diminishes the need for an energy input from the CO2 greenhouse,” he wrote.

List of global warming activists, now skeptics
Growing number of major scientific figures convert to skeptics after reviewing new research
Wednesday, May 16, 2007 By Marc Morano
Following the U.S. Senate's vote today on a global warming measure, there is a shift taking place in climate science. Many former believers in catastrophic man-made global warming have recently reversed themselves and are now climate skeptics. The names below are just a sampling of the prominent scientists who have spoken out recently to oppose the perceived alarmism of man-made global warming.
The media's climate fear factor seemingly grows louder even as the latest science grows less and less alarming by the day. It is also worth noting that the proponents of climate fears are increasingly attempting to suppress dissent by skeptics.
Once Believers, Now Skeptics
Geophysicist Dr. Claude Allegre, a top geophysicist and French Socialist who has authored more than 100 scientific articles and written 11 books and received numerous scientific awards including the Goldschmidt Medal from the Geochemical Society of the United States, 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!" “Glaciers’ chronicles or historical archives point to the fact that climate is a capricious phenomena. This fact is confirmed by mathematical meteorological theories. So, let us be cautious,” Allegre explained in a September 21, 2006 article in the French newspaper L'EXPRESS.
The National Post in Canada also profiled Allegre on March 2, 2007, noting “Allegre has the highest environmental credentials. The author of early environmental books, he fought successful battles to protect the ozone layer from CFCs and public health from lead pollution.” Allegre now calls fears of a climate disaster "simplistic and obscuring the true dangers” mocks "the greenhouse-gas fanatics whose proclamations consist in denouncing man's role on the climate without doing anything about it except organizing conferences and preparing protocols that become dead letters." Allegre, a member of both the French and U.S. Academy of Sciences, had previously expressed concern about manmade global warming. "By burning fossil fuels, man enhanced the concentration of carbon dioxide in the atmosphere which has raised the global mean temperature by half a degree in the last century," Allegre wrote 20 years ago. In addition, Allegre was one of 1500 scientists who signed a November 18, 1992 letter titled “World Scientists' Warning to Humanity” in which the scientists warned that global warming’s “potential risks are very great.”
Geologist Bruno Wiskel of the University of Alberta recently reversed his view of man-made climate change and instead became a global warming skeptic. 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. Wiskel wanted to prove that the Kyoto Protocol’s goals were achievable by people making small changes in their lives. But after further examining the science behind Kyoto, Wiskel reversed his scientific views completely and became such a strong skeptic, that he recently wrote a book titled “The Emperor's New Climate: Debunking the Myth of Global Warming.”
A November 15, 2006 Edmonton Sun article explains Wiskel’s conversion while building his “Kyoto house”: “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.” Wiskel now says “the truth has to start somewhere.” 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. "If you funnel money into things that can't be changed, the money is not going into the places that it is needed,” he said.
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,” Shaviv said in February 2, 2007 Canadian National Post article. 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" and "it is unlikely that [the solar climate link] does not exist,” Shaviv noted pointing to the impact cosmic- rays have on the atmosphere. According to the National Post, Shaviv believes that even a doubling of CO2 in the atmosphere by 2100 "will not dramatically increase the global temperature." “Even if we halved the CO2 output, and the CO2 increase by 2100 would be, say, a 50% increase relative to today instead of a doubled amount, the expected reduction in the rise of global temperature would be less than 0.5C. This is not significant,” Shaviv explained. Shaviv also wrote on August 18, 2006 that a colleague of his believed that “CO2 should have a large effect on climate” so “he set out to reconstruct the phanerozoic temperature. He wanted to find the CO2 signature in the data, but since there was none, he slowly had to change his views.”
Shaviv believes there will be more scientists converting to man-made global warming skepticism as they discover the dearth of evidence. “I think this is common to many of the scientists who think like us (that is, that CO2 is a secondary climate driver). Each one of us was working in his or her own niche. While working there, each one of us realized that things just don't add up to support the AGW (Anthropogenic Global Warming) picture. So many had to change their views,” he wrote.
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,” Evans wrote in an April 30, 2007 blog. “But after 2000 the evidence for carbon emissions gradually got weaker -- better temperature data for the last century, more detailed ice core data, then laboratory evidence that cosmic rays precipitate low clouds,” Evans wrote. “As Lord Keynes famously said, ‘When the facts change, I change my mind. What do you do, sir?’” he added.
Evans noted how he benefited from climate fears as a scientist. “And the political realm in turn fed money back into the scientific community. By the late 1990's, lots of jobs depended on the idea that carbon emissions caused global warming. Many of them were bureaucratic, but there were a lot of science jobs created too. I was on that gravy train, making a high wage in a science job that would not have existed if we didn't believe carbon emissions caused global warming. And so were lots of people around me; and there were international conferences full of such people. And we had political support, the ear of government, big budgets, and we felt fairly important and useful (well, I did anyway). It was great. We were working to save the planet! But starting in about 2000, the last three of the four pieces of evidence outlined above fell away or reversed,” Evans wrote. “The pre-2000 ice core data was the central evidence for believing that atmospheric carbon caused temperature increases. The new ice core data shows that past warmings were *not* initially caused by rises in atmospheric carbon, and says nothing about the strength of any amplification. This piece of evidence casts reasonable doubt that atmospheric carbon had any role in past warmings, while still allowing the possibility that it had a supporting role,” he added. “Unfortunately politics and science have become even more entangled. The science of global warming has become a partisan political issue, so positions become more entrenched. Politicians and the public prefer simple and less-nuanced messages. At the moment the political climate strongly supports carbon emissions as the cause of global warming, to the point of sometimes rubbishing or silencing critics,” he concluded.
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,” Murty explained on August 17, 2006. “I switched to the other side in the early 1990's when Fisheries and Oceans Canada asked me to prepare a position paper and I started to look into the problem seriously,” Murty explained. Murty 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, "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.”
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,” Bellamy added.
Bellamy’s conversion on global warming did not come without a sacrifice as several environmental groups have ended their association with him because of his views on climate change. The severing of relations came despite Bellamy’s long activism for green campaigns. The UK Times reported Bellamy “won respect from hardline environmentalists with his campaigns to save Britain’s peat bogs and other endangered habitats. In Tasmania he was arrested when he tried to prevent loggers cutting down a rainforest.”
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.” de Freitas wrote on August 17, 2006. “I accept there may be small changes. But I see the risk of anything serious to be minute,” he added. “One could reasonably argue that lack of evidence is not a good reason for complacency. But I believe the billions of dollars committed to GW research and lobbying for GW and for Kyoto treaties etc could be better spent on uncontroversial and very real environmental problems (such as air pollution, poor sanitation, provision of clean water and improved health services) that we know affect tens of millions of people,” de Freitas concluded.
de Freitas 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, “Significant [scientific] advances have been made since the [Kyoto] protocol was created, many of which are taking us away from a concern about increasing greenhouse gases.”
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. Bryson, was on the United Nations Global 500 Roll of Honor and was identified by the British Institute of Geographers as the most frequently cited climatologist in the world. “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.

Science and Skepticism
This commentary about science and skepticism comes from Dr. Joe Sobel at accuweather.com
He is careful to not take sides in the global warming debate, but he expresses quite well the need for scientists to be skeptical.

Science and Skepticism
Wednesday, March 07, 2007
Thank you for checking out the AccuWeather Global Warming Center. The purpose of this site is not to be an advocate for or against anthropogenic global warming, but rather to be a clearinghouse of ideas and to facilitate the exchange of information. We are very much opposed to any thoughts of suppressing discussion. We will present information that represents the consensus of the majority of the scientific community. But we will also present opposing points of view.
Remember, science is not a democracy; the majority is not always correct. Remember, the scientific consensus used to be that the Earth is flat and that the sun revolves around the Earth.
In these modern times of zero-second sound bites and rapid global communication, it has become standard for there to be two categories of people in the global warming debate: those who believe that humans are responsible for global warming and everyone else. If you are a skeptic and aren't quite convinced that we know all the answers, you are considered a heretic by the believers.
But, it can be argued that scientists must be skeptics. A scientist may have a theory; however, in order for the scientific method to be honored, the scientist needs to be emotionally unattached to the results. The data will prove whether the theory is correct. Scientists cannot start an experiment with the goal of reaching a particular conclusion. They cannot root for specific results. They cannot change the data to fit any preconceived idea of what the results should be. They need to analyze each piece of data in order to arrive at a conclusion.In other words, they need to be skeptics.
So, whether you are a believer, or a skeptic, we hope you will visit our web site frequently and we look forward to your comments and input in the future.
He is careful to not take sides in the global warming debate, but he expresses quite well the need for scientists to be skeptical.

Science and Skepticism

Thank you for checking out the AccuWeather Global Warming Center. The purpose of this site is not to be an advocate for or against anthropogenic global warming, but rather to be a clearinghouse of ideas and to facilitate the exchange of information. We are very much opposed to any thoughts of suppressing discussion. We will present information that represents the consensus of the majority of the scientific community. But we will also present opposing points of view.
