Growing Number of Scientists are Skeptical of Global Warming Science

Posted: September 14, 2010 in global warming fraud

A friend and colleague recently asked me if there were any real scientists who were skeptical of the science surrounding global warming.  I was mildly surprised because he is an educated man with a background in biology.  However, it made me realize just how effective the campaign by the global warming alarmists to dismiss everyone who doesn’t agree with them as a tiny minority of out-of-the-mainstream kooks.  Both Al Gore and IPCC chairman, R. J. Pachauri, compare skeptics such as me to the members of the Flat Earth Society.  I take particular exception to this comparison since I have more scientific credentials than both of these hypocritical charlatans combined. I have long suspected that whenever credentialed scientists delve into the science behind global warming there is a high probability that they will come away more than skeptical.  Researching this column has confirmed my suspicions. 

The following list is not meant to be exhaustive but I think it pretty much dispels any notion that we are all just kooks.  It certainly dispels Gore’s often-quoted statement that, “the science is settled.”



“I am a skeptic…Global warming has become a new religion.” – Nobel Prize Winner for Physics, Ivar Giaever.  

“Since I am no longer affiliated with any organization nor receiving any funding, I can speak quite frankly….As a scientist I remain skeptical…The main basis of the claim that man’s release of greenhouse gases is the cause of the warming is based almost entirely upon climate models. We all know the frailty of models concerning the air-surface system.” – Atmospheric Scientist Dr. Joanne Simpson, the first woman in the world to receive a PhD in meteorology, and formerly of NASA, who has authored more than 190 studies and has been called “among the most preeminent scientists of the last 100 years.”  

Warming fears are the “worst scientific scandal in history…When people come to know what the truth is, they will feel deceived by science and scientists.” – UN IPCC Japanese Scientist Dr. Kiminori Itoh, an award-winning PhD environmental physical chemist. 

“The IPCC has actually become a closed circuit; it doesn’t listen to others. It doesn’t have open minds… I am really amazed that the Nobel Peace Prize has been given on scientifically incorrect conclusions by people who are not geologists.” – Indian geologist Dr. Arun D. Ahluwalia at Punjab University and a board member of the UN-supported International Year of the Planet.

“So far, real measurements give no ground for concern about a catastrophic future warming.” –  Scientist Dr. Jarl R. Ahlbeck, a chemical engineer at Abo Akademi University in Finland, author of 200 scientific publications and former Greenpeace member.

“Anyone who claims that the debate is over and the conclusions are firm has a fundamentally unscientific approach to one of the most momentous issues of our time.”  – Solar physicist Dr. Pal Brekke, senior advisor to the Norwegian Space Centre in Oslo. Brekke has published more than 40 peer-reviewed scientific articles on the sun and solar interaction with the Earth.

“The models and forecasts of the UN IPCC “are incorrect because they only are based on mathematical models and presented results at scenarios that do not include, for example, solar activity.” – Victor Manuel Velasco Herrera, a researcher at the Institute of Geophysics of the National Autonomous University of Mexico  

“It is a blatant lie put forth in the media that makes it seem there is only a fringe of scientists who don’t buy into anthropogenic global warming.” – U.S Government Atmospheric Scientist Stanley B. Goldenberg of the Hurricane Research Division of NOAA.   

“Even doubling or tripling the amount of carbon dioxide will virtually have little impact, as water vapour and water condensed on particles as clouds dominate the worldwide scene and always will.” – . Geoffrey G. Duffy, a professor in the Department of Chemical and Materials Engineering of the University of Auckland, NZ.

After reading [UN IPCC chairman] Pachauri’s asinine comment [comparing skeptics to] Flat Earthers, it’s hard to remain quiet.” – 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.  

“The Kyoto theorists have put the cart before the horse. It is global warming that triggers higher levels of carbon dioxide in the atmosphere, not the other way round…A large number of critical documents submitted at the 1995 U.N. conference in Madrid vanished without a trace. As a result, the discussion was one-sided and heavily biased, and the U.N. declared global warming to be a scientific fact,” Andrei Kapitsa, a Russian geographer and Antarctic ice core researcher.

“I am convinced that the current alarm over carbon dioxide is mistaken…Fears about man-made global warming are unwarranted and are not based on good science.”Award Winning Physicist Dr. Will Happer, Professor at the Department of Physics at Princeton University and Former Director of Energy Research at the Department of Energy, who has published over 200 scientific papers, and is a fellow of the American Physical Society, The American Association for the Advancement of Science, and the National Academy of Sciences.

“Nature’s regulatory instrument is water vapor: more carbon dioxide leads to less moisture in the air, keeping the overall GHG content in accord with the necessary balance conditions.” – Prominent Hungarian Physicist and environmental researcher Dr. Miklós Zágoni reversed his view of man-made warming and is now a skeptic. Zágoni was once Hungary’s most outspoken supporter of the Kyoto Protocol.

“For how many years must the planet cool before we begin to understand that the planet is not warming? For how many years must cooling go on?” – Geologist Dr. David Gee the chairman of the science committee of the 2008 International Geological Congress who has authored 130 plus peer reviewed papers, and is currently at Uppsala University in Sweden.  

“Gore prompted me to start delving into the science again and I quickly found myself solidly in the skeptic camp…Climate models can at best be useful for explaining climate changes after the fact.” – Meteorologist Hajo Smit of Holland, who reversed his belief in man-made warming to become a skeptic, is a former member of the Dutch UN IPCC committee.  

“The quantity of CO2 we produce is insignificant in terms of the natural circulation between air, water and soil… I am doing a detailed assessment of the UN IPCC reports and the Summaries for Policy Makers, identifying the way in which the Summaries have distorted the science.” – South Afican Nuclear Physicist and Chemical Engineer Dr. Philip Lloyd, a UN IPCC co-coordinating lead author who has authored over 150 refereed publications.


“Many [scientists] are now searching for a way to back out quietly (from promoting warming fears), without having their professional careers ruined.” – Atmospheric physicist James A. Peden, formerly of the Space Research and Coordination Center in Pittsburgh.

“All those urging action to curb global warming need to take off the blinkers and give some thought to what we should do if we are facing global cooling instead.” – Geophysicist Dr. Phil Chapman, an astronautical engineer and former NASA astronaut, served as staff physicist at MIT (Massachusetts Institute of Technology)

 “Creating an ideology pegged to carbon dioxide is a dangerous nonsense…The present alarm on climate change is an instrument of social control, a pretext for major businesses and political battle. It became an ideology, which is concerning.” – Environmental Scientist Professor Delgado Domingos of Portugal, the founder of the Numerical Weather Forecast group, has more than 150 published articles.

“CO2 emissions make absolutely no difference one way or another….Every scientist knows this, but it doesn’t pay to say so…Global warming, as a political vehicle, keeps Europeans in the driver’s seat and developing nations walking barefoot.” – Dr. Takeda Kunihiko, vice-chancellor of the Institute of Science and Technology Research at Chubu University in Japan.

“The [global warming] scaremongering has its justification in the fact that it is something that generates funds.– Award-winning Paleontologist Dr. Eduardo Tonni, of the Committee for Scientific Research in Buenos Aires and head of the Paleontology Department at the University of La Plata.

“Whatever the weather, it’s not being caused by global warming. If anything, the climate may be starting into a cooling period.” Atmospheric scientist Dr. Art V. Douglas, former Chair of the Atmospheric Sciences Department at Creighton University in Omaha, Nebraska, and is the author of numerous papers for peer-reviewed publications.

“But there is no falsifiable scientific basis whatever to assert this warming is caused by human-produced greenhouse gasses because current physical theory is too grossly inadequate to establish any cause at all.” – Chemist Dr. Patrick Frank, who has authored more than 50 peer-reviewed articles.  

“The ‘global warming scare’ is being used as a political tool to increase government control over American lives, incomes and decision making. It has no place in the Society’s activities.” – Award-Winning NASA Astronaut/Geologist and Moonwalker Jack Schmitt who flew on the Apollo 17 mission and formerly of the Norwegian Geological Survey and for the U.S. Geological Survey.  

“Earth has cooled since 1998 in defiance of the predictions by the UN-IPCC….The global temperature for 2007 was the coldest in a decade and the coldest of the millennium…which is why ‘global warming’ is now called ‘climate change.’” – Climatologist Dr. Richard Keen of the Department of Atmospheric and Oceanic Sciences at the University of Colorado. 

“I have yet to see credible proof of carbon dioxide driving climate change, yet alone man-made CO2 driving it. The atmospheric hot-spot is missing and the ice core data refute this. When will we collectively awake from this deceptive delusion?” – Dr. G LeBlanc Smith, a retired Principal Research Scientist with Australia’s CSIRO.      

The new scientific report “directly challenges the conclusions of the IPCC Summary that human emissions of carbon dioxide are causing dangerous and unprecedented warming.” – Quantitative Economist Kenneth A. Haapala, the past president of the prestigious Philosophical Society of Washington, the oldest scientific society in Washington (founded 1871), has reviewed hundreds of reports based on quantitative techniques. Haapala co-authored the report “Nature, Not Human Activity, Rules the Climate” 

“I think that climatic changes have a natural causes according many geological data…I am very glad to sign the U.S. Senate’s report of scientists against the theory of man-made global warming.” Geology Professor Uberto Crescenti of the University G.d’Annunzio in Italy is the past president of the Society of Italian Geologists. 

“I am appalled at the state of discord in the field of climate science…There is no observational evidence that the addition of anthropogenic greenhouse gas emissions have caused any temperature perturbations in the atmosphere.” Award-winning atmospheric scientist Dr. George T. Wolff, former member of the EPA’s Science Advisory Board, served on a committee of the National Oceanic and Atmospheric Administration (NOAA) and authored more than 90 peer-reviewed studies.  

“The sky is not burning, and to claim that it is amounts to journalistic malpractice…the press only promotes the global warming alarmists and ignores or minimizes those of us who are skeptical.” Chemist Dr. Mark L. Campbell, a professor of chemistry at the U.S. Naval Academy in Annapolis, MD, who has published numerous studies in the Journal of the American Chemical Society on topics such as methane.   

“Once again we have misleading climate change pronouncements being based on data errors, data errors detected by non-UN, non-IPCC, non-peer-reviewed external observersThis is exactly what happens when you base your arguments on ‘consensus science’ and not scientific fact.” – Professor Dr. Doug L. Hoffman, a mathematician, computer programmer, and engineer, who worked on environmental models and conducted research in molecular dynamics simulations. Hoffman co-authored the 2009 book, The Resilient Earth, described as “bringing a dose of skeptical reality to climate science and the global warming debate.” 

“The questions are scientific, but the UN answers are political. The global warming debate is hardly about science. Computer Modeler and Engineer Allen Simmons, who worked 12 years with NASA’s top climate scientists and wrote computer systems software for the world’s first weather satellites and aided in the development of computer systems for polar orbiting satellites. Simmons co-authored the new skeptical book The Resilient Earth.  

Belief in climate models compared to “ancient astrology”… “I believe the anthropogenic (man-made) effect for climate change is still only one of the hypotheses to explain the variability of climate.” Award-winning Japanese Physicist Dr. Kanya Kusano, program director of the Japan Agency for Marine-Earth Science and Technology who’s research “focuses on the immaturity of simulation work cited in support of the theory of anthropogenic climate change.” compared climate models to “ancient astrology.” 

“The recent ‘panic’ to control GHG (greenhouse gas) emissions and billions of dollars being dedicated for the task has me deeply concerned that US, and other countries are spending precious global funds to stop global warming, when it is primarily being driven by natural forcing mechanisms.” Climatologist and Paloeclimate researcher Dr. Diane Douglas, who has authored or edited over 200 technical reports, specialized in the reconstruction of a variety of proxy data and has worked for the Department of Energy and conducted research for the Arizona State Office of Climatology to investigate the Little Ice Age.  

“Temperature measurements show that the [climate model-predicted mid-troposphere] hot zone is non-existent. This is more than sufficient to invalidate global climate models and projections made with them!”- UN IPCC Scientist Dr. Steven M. Japar, a PhD atmospheric chemist who was part of Intergovernmental Panel on Climate Change’s (IPCC) Second (1995) and Third (2001) Assessment Reports, and has authored 83 peer-reviewed publications and in the areas of climate change, atmospheric chemistry, air pollutions and vehicle emissions.  

“The cause of these global changes is fundamentally due to the Sun and its effect on the Earth as it moves about in its orbit. Not from man-made activities.” – Retired Award Winning NASA Atmospheric Scientist Dr. William W. Vaughan, recipient of the NASA Exceptional Service Medal, a former Division Chief of NASA’s Marshall Space Flight Center and author more than 100 refereed journal articles, monographs, and papers.  

“Unfortunately, Climate Science has become Political Science…It is tragic that some perhaps well-meaning but politically motivated scientists who should know better have whipped up a global frenzy about a phenomena which is statistically questionable at best.” – Award-Winning Princeton University Physicist Dr. Robert H.

“I do not find the supposed scientific consensus among my colleagues… Curiously, it is a feature of man-made global warming that every fact confirms it: rising temperatures or decreasing temperatures. No matter what the weather, some model of global warming offers a watertight explanation.” Earth Scientist Dr. Javier Cuadros of the UK Natural History Museum, who specializes in Clay Mineralogy and has published more than 30 scientific papers 

“It is amazing to me, as a professional geologist, how many otherwise intelligent people have, as some may say, ‘drunk the Al Gore Kool-Aid’ concerning global climate change.” Professional Geologist Earl F. Titcomb Jr. has co-authored analyses of geological and seismological hazards.  

“Let’s be clear: the work of science has nothing whatever to do with consensus [which] is the business of politics.  . . . What is relevant is reproducible results.  The greatest scientists in history are great precisely because they broke with the consensus.’” Atmospheric Scientist Timothy R. Minnich, who has more than 30 years experience in the design and management of a wide range of air quality investigations for industry and government, is a past member of the American Meteorological Society and specializes in issues like acid rain and ozone, and has authored or co-authored numerous technical publications and reports.

Scotto, who has more than 30 years air quality consulting experience, served as a manager for an EPA Superfund contract and is co-founder of Minnich and Scotto, Inc., a full-service air quality consulting firm. He also is a past member of the American Meteorological Society (AMS). Scotto, a meteorologist who has authored or co-authored numerous technical publications and reports.  

“Whether the ice caps melt, or expand — whatever happens — the AGW (anthropogenic global warming) theorists claim it confirms their theory. A perfect example of a pseudo-science like astrology.” Mathematical Physicist Dr. Frank Tipler, professor at Tulane University has authored 58 peer-reviewed publications and five books.

    This is quite impressive. Even though me and my colleagues were skeptical the popular press made it sound as though we were insignificant. Thanks for this. I’m going to forward this to everyone I know.

    Wow. Bravo

  4. Yair says:

    Absolutely jaw-dropping. Usually you come to think that the majority of the scientific community is in consensus about global warming, but these comments never make it to the so called “media” instead we have people like Al Gore that just influence because of their fame.

    I have to wonder, with all these contradictions to the global warming theory, perhaps this is a classic case of “the ends justify the means.” That is, essentially scaring into believing that our CO2 emissions are causing global warming so that we can rid ourselves of fossil fuels and the contaminants that are a bi-product of the CO2 and CO emissions.

    I am not for this ends justify the means, but I am intrigued about the relentless onslaught of global warming theories and their acceptance

    • Thanks, Yair. It really is all about an enormous transfer of wealth from the industrialized western world to the underdeveloped world. The ultimate goal is to tax us (like with pending cap and trade legislation) according to the size of our carbon footprint and then redistribute that money to those poor countries who do not have an affluent (carbon dioxide generating) society. It means Americans will be taxed thousands of dollars more each year because of our evil ways. This has nothing to do with science. It only has to do with social engineering on a global scale. You are going to be taxed for breathing! These clowns are misusing science as a means to accomplish their political agenda.

  5. MoreLikeAFishThanALobsterIs says:

    You have collected relevant quotes from 50 individuals with backgrounds in science who are skeptical of global climate change and/or of man’s role in global climate change. That proves that there are at least 50 individuals with backgrounds in science who agree with you. As a scientist and skeptic yourself, you know that it doesn’t prove anything one way or the other about the correctness of their opinion or their kookiness level. If you tried to present this as proof of anything (except that the fact that these people hold this opinion) you would be guilty of using a logical fallacy, in particular the logical fallacy known as the “argument from authority”.

    It is legitimate to consider the training and experience of an individual when examining their assessment of a claim but it is still possible for highly educated individuals, and a consensus of highly educated individuals, to be wrong. Speaking from authority does not make a claim true. This is really no better than the creationist’s lists of scientists who doubt evolution. As Dawkins so eloquently teaches us, humans brains evolved to cope with the kinds of numbers and probabilities that we needed in order to survive in our habitats. It is easy to convince people that 50 is a big consensus but there are almost 7 billion people in the world at this point. What percentage of that population would qualify as individuals with backgrounds in science? Even if the percentage is very small, the total number is going to be fairly large compared to 50. And that too, proves absolutely nothing about the correctness or kookiness levels of global climate change claims.

    • I agree with everything you say, and anyone making reference to Dawkins brings a smile to my face. However, you seem to have missed the whole point to this post. It was not meant to prove or disprove a scientific hypothesis. It was merely a response to the constant claims that the science is settled and that anthropogenic global warming is a fact. It was a response to the constant droning about a consensus having already been reached about the reality of man-induced gobal warming. This political and media blitz has a large segment of society duped. My only purpose was to demonstrate that the science is certainly not settled. I didn’t even know that the list was 50. I didn’t count them. I could have easily drummed up ten times that number. The number is only marginally significant. On the other hand, you should be aware that a total of 52 scientists from the “other side” were responsible for writing the entire IPCC report, not the thousands and thousands as claimed by the dupers.

  6. MoreLikeAFishThanALobsterIs says:

    I didn’t count them either. I am not quite that bored.

    If you say that the point of your post is just to provide an answer to the “argument from authority” challenge from IPCC supporters, then I guess the only reasonable call is double technicals. I am usually not a fan of that call. In this case, it seems the best way to get on with the game. I am looking forward to your next post.

  7. t_fish says:

    So good to see this post. It is nice to know that my views are shared by so many other notable individuals. I have been studying the literature on this subject for several years now and can’t for the life of me figure out how anyone takes these AGW people seriously. Looking forward to more of your post.

  8. jasperb says:

    This is both comforting and reassuring. Glad I am in such good company. If you listen to the media they make it sound as though everyone has bought into this scam. My own observation is that the proponents of AGW are becoming fewer and fewer. I shared this with many of my colleagues and the response has been raised eyebrows by all of them. Incidentally, I am a physics and astronomy instructor at a small college.

  9. jendo321 says:

    I would love to see more stuff like this.

  10. sammisen says:

    I have printed this out and I am going to hang it in my classroom. I teach geology and I am always being asked about global warming. My students are always surprised to learn that I am not a convert to the religion.
