The Science is Not Settled

Scientist Skeptics of the Theory of Man-made Climate Change

“Despite what you may have heard in the media, there is nothing like a consensus of scientific opinion that this is a problem.” — Tom Tripp of the United Nations’ IPCC

The Myth of the Climate Change ‘97%’
“The assertion that 97% of scientists believe that climate change is a man-made, urgent problem is a fiction. The so-called consensus comes from a handful of surveys and abstract-counting exercises that have been contradicted by more reliable research….” [more]

31,000+ Scientists Sign Petition Denying Man-made Global Warming
“There is no convincing scientific evidence that human release of carbon dioxide, methane, or other greenhouse gases is causing or will, in the forseeable future, cause catastrophic heating of the Earth’s atmosphere and disruption of the Earth’s climate. Moreover, there is substantial scientific evidence that increases in atmospheric carbon dioxide produce many beneficial effects upon the natural plant and animal environments of the earth.” [more]

1,000+ International Scientists Dissent Over Man-made Global Warming Claims
“Updated from the 2007 groundbreaking U.S. Senate Report of over 400 scientists who voiced skepticism about the so-called global warming ‘consensus‘, [the updated 2010 report] features the skeptical voices of over 1,000 international scientists, including many current and former UN IPCC scientists, who have now turned against the UN IPCC. This updated 2010 report includes a dramatic increase of over 300 additional (and growing) scientists and climate researchers since the last update in March 2009. This report’s release coincides with the 2010 UN global warming summit in being held in Cancun.” [more]

Majority of 1,862 American Meteorological Society Members Surveyed are Global Warming Skeptics
A recent survey of American Meteorological Society members shows meteorologists are skeptical that humans are causing a global warming crisis. The survey confirms what many scientists have been reporting for years; the politically focused bureaucratic leadership of many science organizations is severely out of touch with the scientists themselves regarding global warming issues…. Among those meteorologists who believe global warming is happening, only a modest majority (59%) believe humans are the primary cause. More importantly, only 38% of respondents who believe global warming is occurring say it will be very harmful during the next 100 years.” [more]

Majority of 1,077 Scientists Surveyed Are Skeptics of Climate Alarmism
“… a strong majority of the 1,077 [geoscientists surveyed] believe that nature is the primary cause of recent global warming and/or that future global warming will not be a very serious problem…. One interesting aspect of this new survey is the unmistakably alarmist bent of the survey takers…. Alarmists will have a hard time arguing the survey is biased or somehow connected to the ‘vast right-wing climate denial machine.’ Another interesting aspect of this new survey is that it reports on the beliefs of scientists themselves rather than bureaucrats who often publish alarmist statements without polling their member scientists. We now have meteorologists, geoscientists and engineers all reporting that they are skeptics of an asserted global warming crisis, yet the bureaucrats of these organizations_ frequently suck up to the media and suck up to government grant providers by trying to tell us the opposite of what their scientist members actually believe. People who look behind the self-serving statements by global warming alarmists about an alleged “consensus” have always known that no such alarmist consensus exists among scientists. Now that we have access to hard surveys of scientists themselves, it is becoming clear that not only do many scientists dispute the asserted global warming crisis, but these skeptical scientists may indeed form a scientific consensus.” [more]

125+ Scientists Pen Open Climate Letter to UN Secretary General: The Science is Unclear
“We the undersigned, qualified in climate-related matters, wish to state that current scientific knowledge does not substantiate your [global warming] assertions…. Climate changes naturally all the time, sometimes dramatically. The hypothesis that our emissions of CO2 have caused, or will cause, dangerous warming is not supported by the evidence…. There is no sound reason for the costly, restrictive public policy decisions proposed at the U.N. climate conference in Qatar. Rigorous analysis of unbiased observational data does not support the projections of future global warming predicted by computer models now proven to exaggerate warming and its effects….” [more]

100+ Scientists Rebuke Obama as “Simply Incorrect” on Global Warming
“We, the undersigned scientists, maintain that the case for alarm regarding climate change is grossly overstated. Surface temperature changes over the past century have been episodic and modest and there has been no net global warming for over a decade now.1,2 After controlling for population growth and property values, there has been no increase in damages from severe weather-related events.3 The computer models forecasting rapid temperature change abjectly fail to explain recent climate behavior.4 Mr. President, your characterization of the scientific facts regarding climate change and the degree of certainty informing the scientific debate is simply incorrect.” [more]

80 Prominent Scientists, Researchers & Environmental Business Leaders Call on American Physical Society to Revise its Policy Statement on Climate Change
“Greenhouse gas emissions, such as carbon dioxide, methane, and nitrous oxide, accompany human industrial and agricultural activity. While substantial concern has been expressed that emissions may cause significant climate change, measured or reconstructed temperature records indicate that 20th [and] 21st century changes are neither exceptional nor persistent, and the historical and geological records show many periods warmer than today. In addition, there is an extensive scientific literature that examines beneficial effects of increased levels of carbon dioxide for both plants and animals. Studies of a variety of natural processes, including ocean cycles and solar variability, indicate that they can account for variations in the Earth’s climate on the time scale of decades and centuries. Current climate models appear insufficiently reliable to properly account for natural and anthropogenic contributions to past climate change, much less project future climate.” [more]

60 Expert Canadian Scientists Write Prime Minister to Debunk Global Warming Alarmism
“‘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’…. We believe the Canadian public and government decision-makers need and deserve to hear the whole story concerning this very complex issue. It was only 30 years ago that many of today’s global-warming alarmists were telling us that the world was in the midst of a global-cooling catastrophe. But the science continued to evolve, and still does, even though so many choose to ignore it when it does not fit with predetermined political agendas.” [more]

16 Scientists: No Need to Panic About Global Warming
“A candidate for public office in any contemporary democracy may have to consider what, if anything, to do about “global warming.” Candidates  should understand that the oft-repeated claim that nearly all scientists demand that something dramatic be done to stop global warming is not true. In fact, a large and growing number of distinguished scientists and engineers do not agree that drastic actions on global warming are needed….” [more]

Two Moonwalkers Defy Al Gore’s Claims
“NASA’s Dr. Aldrin — who earned a Doctorate of Science in Astronautics at MIT — declared he was skeptical of man-made climate fears in a July 3, 2009 UK Telegraph interview…. Award-Winning NASA Astronaut/Geologist and Moonwalker Jack Schmitt, formerly of the Norwegian Geological Survey and the U.S. Geological Survey, a member of the Geological Society of America, American Geophysical Union, and the American Association for the Advancement of Science, rejected man-made climate change concerns in 2008. ‘The “global warming scare” is being used as a political tool to increase government control over American lives, incomes and decision making.'” [more]

“Godfather” of Global Warming Acknowledges He Was Unduly Alarmist
“Having observed that global temperatures since the turn of the millennium have not gone up in the way computer-based climate models predicted, Lovelock acknowledged, ‘the problem is we don’t know what the climate is doing. We thought we knew 20 years ago.’ Now, Lovelock has given a follow-up interview to the UK’s Guardian newspaper in which he delivers more bombshells sure to anger the global green movement, which for years worshipped his Gaia theory and apocalyptic predictions that billions would die from man-made climate change by the end of this century…. [Lovelock] says it’s now clear the doomsday predictions, including his own (and Al Gore’s) were incorrect.” [more]

Princeton Physicist Declares Congress ‘Badly Misinformed’ on Global Warming
Award-winning Princeton University Physicist Dr. Will Happer, who has published over 200 peer-reviewed scientific papers, warned Congress that it has been ‘badly misinformed’ about man-made global warming fears…. ‘Congress has been getting bad intelligence,’ Happer, who was reportedly fired by former Vice President Al Gore in 1993 for failing to adhere to Gore’s scientific views, declared in a July 6, 2009 interview…. ‘Congress has been badly misinformed about the so-called science that supports the claim that increasing CO2 levels will bring about catastrophic climate change,’ Happer explained… Happer did not mince words, calling the movement to promote man-made global warming fears a ‘climate change cult’ and noted that ‘zealots’ promoting climate fears ‘are actually extremely ignorant.'” ” [more]

Nobel Prize-Winning Physicist Resigns Over Global Warming
“Dr. Ivar Giaever, a former professor with Rensselaer Polytechnic Institute and the 1973 winner of the Nobel Prize in physics, abruptly announced his resignation Tuesday, Sept. 13 [2011], from the premier physics society in disgust over its officially stated policy that “global warming is occurring.” [more, more]

Prominent Physicist Resigns from American Physical Society Over Global Warming Scam
Letter to APS from Physicist Harold Lewis: “For reasons that will soon become clear, my former pride at being an APS Fellow all these years has been turned into shame, and I am forced, with no pleasure at all, to offer you my resignation from the Society. It is of course, the global warming scam, with the (literally) trillions of dollars driving it, that has corrupted so many scientists, and has carried APS before it like a rogue wave. It is the greatest and most successful pseudoscientific fraud I have seen in my long life as a physicist.” [more]

Respected Botanist David Bellamy an Early Critic of Man-made Global Warming Theory
“The idiot fringe have accused me of being like a Holocaust denier, which is ludicrous. Climate change is all about cycles, it’s a natural thing and has always happened. When the Romans lived in Britain they were growing very good red grapes and making wine on the borders of Scotland. It was evidently a lot warmer. The thing that annoys me most is that there are genuine environmental problems that desperately require attention. I’m still an environmentalist, I’m still a Green and I’m still campaigning to stop the destruction of the biodiversity of the world. But money will be wasted on trying to solve this global warming ‘problem’ that I would much rather was used for looking after the people of the world.” [more]

Greenpeace co-founder: No Scientific Proof Humans are Dominant Cause of Warming Climate
“A co-founder of Greenpeace told lawmakers there is no evidence man is contributing to climate change, and said he left the group when it became more interested in politics than the environment. Patrick Moore, a Canadian ecologist and business consultant who was a member of Greenpeace from 1971-86, told members of the Senate Environment and Public Works Committee environmental groups like the one he helped establish use faulty computer models and scare tactics in promoting claims man-made gases are heating up the planet…. ” [more]

Weather Channel Founder: There is no significant man-made global warming at this time, there has been none in the past and there is no reason to fear any in the future.
“John Coleman, who co-founded the Weather Channel, shocked academics by insisting the theory of man-made climate change was no longer scientifically credible. Instead, what ‘little evidence’ there is for rising global temperatures points to a ‘natural phenomenon’ within a developing eco-system. In an open letter attacking the Intergovernmental Panel on Climate Change, he wrote: ‘The ocean is not rising significantly.”The polar ice is increasing, not melting away. Polar Bears are increasing in number. Heat waves have actually diminished, not increased. There is not an uptick in the number or strength of storms (in fact storms are diminishing). I have studied this topic seriously for years. It has become a political and environment agenda item, but the science is not valid.'” [more]

Professor Emeritus of Atmospheric Sciences at MIT: The move from global warming to climate change indicated the silliness of this issue
“The move from global warming to climate change indicated the silliness of this issue. The climate has been changing since the Earth was formed. This normal course is now taken to be evidence of doom….  World leaders proclaim that climate change is our greatest problem, demonizing carbon dioxide. Yet atmospheric levels of carbon dioxide have been vastly higher through most of Earth’s history. Climates both warmer and colder than the present have coexisted with these higher levels. Currently elevated levels of carbon dioxide have contributed to increases in agricultural productivity. Indeed, climatologists before the recent global warming hysteria referred to warm periods as ‘climate optima.’ Yet world leaders are embarking on costly policies that have no capacity to replace fossil fuels but enrich crony capitalists at public expense, increasing costs for all, and restricting access to energy to the world’s poorest populations that still lack access to electricity’s immense benefits. Billions of dollars have been poured into studies supporting climate alarm, and trillions of dollars have been involved in overthrowing the energy economy. So it is unsurprising that great efforts have been made to ramp up hysteria, even as the case for climate alarm is disintegrating.” — Dr. Richard Lindzen, professor emeritus of atmospheric sciences at MIT

Theoretical physicist and Democrat voter: How does it happen that a whole generation of scientific experts is blind to obvious facts?
“I’m 100 percent Democrat myself, and I like Obama. But he took the wrong side on [climate change], and the Republicans took the right side…. [Climate change] is not a scientific mystery but a human mystery. How does it happen that a whole generation of scientific experts is blind to obvious facts?…. What has happened in the past 10 years is that the discrepancies between what’s observed and what’s predicted have become much stronger. It’s clear now the models are wrong, but it wasn’t so clear 10 years ago. I can’t say if they’ll always be wrong, but the observations are improving and so the models are becoming more verifiable…. To any unprejudiced person reading this account, the facts should be obvious: that the non-climatic effects of carbon dioxide as a sustainer of wildlife and crop plants are enormously beneficial, that the possibly harmful climatic effects of carbon dioxide have been greatly exaggerated, and that the benefits clearly outweigh the possible damage.” — Retired professor of physics at the Institute for Advanced Study at Princeton University

France’s Chief Weatherman: Climatologists and politicians have taken the world hostage with misleading data
“Every night I address five million French people to talk to you about the wind, the clouds and the sun. And yet there is something important, very important that I haven’t been able to tell you, because it’s neither the time nor the place to do so…. We are hostage to a planetary scandal over climate change – a war machine whose aim is to keep us in fear…. We are undoubtedly on a plateau in terms of warming and the cyclical variability of the climate doesn’t not allow us to envisage if the natural rhythm will tomorrow lead us towards a fall, a stagnation or a rise (in temperature).” — Philippe Verdier, French Meteorologist
