31,487 American scientists have signed this petition, including 9,029 with PhDs.
Purpose of Petition
The purpose of the Petition Project is to demonstrate that the claim of “settled science” and an overwhelming “consensus” in favour of the hypothesis of human-caused global warming and consequent climatological damage is wrong. No such consensus or settled science exists. As indicated by the petition text and signatory list, a very large number of American scientists reject this hypothesis. [see more below menu]

Publicists at the United Nations, Mr. Al Gore, and their supporters frequently claim that only a few “skeptics” remain – skeptics who are still unconvinced about the existence of a catastrophic human-caused global warming emergency.
It is evident that 31,487 Americans with university degrees in science – including 9,029 PhDs, are not “a few.” Moreover, from the clear and strong petition statement that they have signed, it is evident that these 31,487 American scientists are not “skeptics.”
These scientists are instead convinced that the human-caused global warming hypothesis is without scientific validity and that government action on the basis of this hypothesis would unnecessarily and counterproductively damage both human prosperity and the natural environment of the Earth.
Letter From Frederick Seitz
This letter from Professor Frederick Seitz is circulated with the petition. Physicist Frederick Seitz was President of the US National Academy of Sciences and of Rockefeller University. He received the National Medal of Science, the Compton Award, the Franklin Medal, and numerous other awards, including honorary doctorates from 32 Universities around the world. In August 2007, Dr. Seitz reviewed and approved the article by Robinson, Robinson, and Soon that is circulated with the petition and gave his enthusiastic approval to the continuation of the Petition Project. A vigorous supporter of the Petition Project since its inception in 1998, Professor Seitz died on March 2nd, 2008. For more biographical information about Dr. Seitz, please click here.

Summary of Peer-Reviewed Research
Most scientists have a detailed knowledge of their own narrow field of specialization, a general knowledge of fundamental science, an understanding of the scientific method, and a mental model that encompasses a broad range of scientific disciplines. This model serves as the basis of their thoughts about scientific questions.
When a scientist desires to refine his understanding of a specific scientific subject, he often begins by reading one or more review articles about that topic. As he reads, he compares the facts given in the review with his mental model of the subject, refining his model and updating it with current information. Review articles do not present new discoveries. The essential facts given in the review must be referenced to the peer-reviewed scientific research literature, so that the reader can check the assertions and conclusions of the article and obtain more detailed information about aspects that interest him.
A 12-page review article about the human-caused global warming hypothesis is circulated with the petition. Click Here.
The factual information cited in this article is referenced to the underlying research literature, in this case by 132 references listed at the end of the article. Although written primarily for scientists, most of this article can be understood without formal scientific training. This article was submitted to many scientists for comments and suggestions before it was finalized and submitted for publication. It then underwent ordinary peer review by the publishing journal.
The United Nations IPCC also publishes a research review in the form of a voluminous, occasionally-updated report on the subject of climate change, which the United Nations asserts is “authored” by approximately 600 scientists. [quote: The IPCC does not conduct its own research. IPCC reports are neutral, policy-relevant but not policy-prescriptive.] These “authors” are not, however – as is ordinarily the custom in science – permitted power of approval the published review of which they are putative authors. They are permitted to comment on the draft text, but the final text neither conforms to nor includes many of their comments. The final text conforms instead to the United Nations objective of building support for world taxation and rationing of industrially-useful energy.

So far The Express, a major British newspaper, and the American news service WND, have provided favorable coverage of the letter. The Express article has also been linked to by the Drudge Report, giving it wide exposure.
How Petition is Circulated
This petition is primarily circulated by U. S. Postal Service mailing to scientists. Included in this mailing are the petition card, the letter from Frederick Seitz, the review article, and a return envelope. If a scientist wishes to sign, he fills out the petition and mails it to the project by first class mail.
Additionally, many petition signers obtain petition cards from their colleagues, who request these cards from the project.
A scientist can also obtain a copy of the petition from this Internet website, sign, and mail it. Fewer than 5% of the current signatories obtained their petition in this way.
Petition project volunteers evaluate each signers’ credentials, verify signer identities, and, if appropriate, add the signer’s name to the petition list. Download and print this copy:
Qualifications of Signers
Signatories are approved for inclusion in the Petition Project list if they have obtained formal educational degrees at the level of Bachelor of Science or higher in appropriate scientific fields. The petition has been circulated only in the United States.
The current list of petition signers includes 9,029 PhD; 7,157 MS; 2,586 MD and DVM; and 12,715 BS or equivalent academic degrees. Most of the MD and DVM signers also have underlying degrees in basic science.
All of the listed signers have formal educations in fields of specialization that suitably qualify them to evaluate the research data related to the petition statement. Many of the signers currently work in climatological, meteorological, atmospheric, environmental, geophysical, astronomical, and biological fields directly involved in the climate change controversy.
The Petition Project classifies petition signers on the basis of their formal academic training, as summarized below. Scientists often pursue specialized fields of endeavor that are different from their formal education, but their underlying training can be applied to any scientific field in which they become interested.
Outlined below are the numbers of Petition Project signatories, subdivided by educational specialties. These have been combined, as indicated, into seven categories.
1. Atmospheric, environmental, and Earth sciences includes 3,805 scientists trained in specialties directly related to the physical environment of the Earth and the past and current phenomena that affect that environment.
2. Computer and mathematical sciences includes 935 scientists trained in computer and mathematical methods. Since the human-caused global warming hypothesis rests entirely upon mathematical computer projections and not upon experimental observations, these sciences are especially important in evaluating this hypothesis.
3. Physics and aerospace sciences include 5,812 scientists trained in the fundamental physical and molecular properties of gases, liquids, and solids, which are essential to understanding the physical properties of the atmosphere and Earth.
4. Chemistry includes 4,822 scientists trained in the molecular interactions and behaviors of the substances of which the atmosphere and Earth are composed.
5. Biology and agriculture includes 2,965 scientists trained in the functional and environmental requirements of living things on the Earth.
6. Medicine includes 3,046 scientists trained in the functional and environmental requirements of human beings on the Earth.
7. Engineering and general science includes 10,102 scientists trained primarily in the many engineering specialties required to maintain modern civilization and the prosperity required for all human actions, including environmental programs.

John Coleman’s Open Letter
Dear UCLA Hammer Forum officials,
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. Efforts to prove the theory that carbon dioxide is a significant “greenhouse” gas and pollutant causing significant warming or weather effects have failed. There has been no warming over 18 years. William Happer, Ph.D., Princeton University, Richard Lindzen, Ph.D., Massachusetts Institute of Technology, Willie Soon, Ph.D., Harvard Smithsonian Observatory, John Christy, Ph.D., University of Alabama and 9,000 other Ph.D. scientists all agree with my opening two sentences.
Yet at your October 23 Hammer Forum on Climate Change you have scheduled as your only speakers two people who continue to present the failed science as though it is the final and complete story on global warming/climate change. This is [a] major mistake.
I urge you to re-examine your plan. It is important to have those who attend know that there is no climate crisis. 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.
I am the founder of The Weather Channel and a winner of the American Meteorological Society honor as Broadcast Meteorologist of the Year. I am not a wacko flat Earther. Nor am I a “paid shill” (as has been claimed) of the Koch Brothers. I am a serious Professional. I am strongly urging you to reconsider your plan.
I can be reached at 858-xxx-xxxx (redacted by Anthony) and will be pleased the discuss this matter with you and answer questions. I will be happy to provide links to all of the points I have made in this email. As a quick scientific reference you may wish to look at the website of the Non-governmental Panel on Climate Change. http://climatechangereconsidered.org/
My best regards,
A copy of this email has been supplied to The LA Times, KCBS/KTLA and NBC4 Los Angeles
(h/t to Eric Worrall for the reminder. John sent me the text of the letter two days ago)
In The Express article they add:
Climate expert William Happer, from Princeton University, supported Mr Coleman’s claims.
He added: “No chemical compound in the atmosphere has a worse reputation than CO2, thanks to the single-minded demonization of this natural and essential atmospheric gas by advocates of government control and energy production.
“The incredible list of supposed horrors that increasing carbon dioxide will bring the world is pure belief disguised as science.”
In 2010 a high-level inquiry by the InterAcademy Council found there was “little evidence” to support the IPCC’s claims about global warming.
It also said the panel had purposely emphasised the negative impacts of climate change and made “substantive findings” based on little proof.Source

‘Global Warming’ Data Exaggerated 50% Over Last 50 Years, New Evidence Shows
The official data used for “global warming” fearmongering has been exaggerated by up to 50 percent over the last 50 years, bombshell new evidence has revealed.
The new groundbreaking research, compiled by two atmospheric scientists at the University of Alabama in Huntsville, Dr. Roy Spencer and Professor John Christy, shows 50% less warming over 50 years across the eastern United States than official data claims.
The new evidence deals a major blow to the widespread use of regularly adjusted global and local surface temperature datasets showing increasingly implausible rates of warming.
The research attempts to remove distortions caused by increasing urban heat and uses human-made structure density data over 50 years supplied by the Landsat satellites.
It compares the official National Oceanic and Atmospheric Administration (NOAA) homogenized surface temperature dataset and exposes a 50% reduction in the warming trend.
Dr. Spencer and Professor Christy used a dataset of urbanization changes called “Built-Up” to determine the average effect that urbanization has had on surface temperatures.
Urbanization differences were compared to temperature differences from closely spaced weather stations.
The temperature plotted was in the morning during the summertime.
In a posting on Dr. Spencer’s blog, a full methodology of the project is shown here.
Dr. Spencer argues that the “Built-Up” dataset, which extends back to the 1970s, will be useful in “de-urbanizing” land-based surface temperature measurements in the U.S. as well as other countries.

My Global Warming Skepticism, for Dummies
by Dr Spencer
I receive many e-mails, and a recurring complaint is that many of my posts are too technical to understand. This morning’s installment arrived with the subject line, “Please Talk to Us”, and suggested I provide short, concise, easily understood summaries and explanations “for dummies”.
So, here’s a list of basic climate change questions, and brief answers based upon what I know today. I might update them as I receive suggestions and comments. I will also be adding links to other sources, and some visual aids, as appropriate.
Deja vu tells me I might have done this once before, but I’m too lazy to go back and see. So, I’ll start over from scratch. (Insert smiley)
It is important to understand at the outset that those of us who are skeptical of mankind’s influence on climate have a wide variety of views on the subject, and we can’t all be right. In fact, in this business, it is really easy to be wrong. It seems like everyone has a theory of what causes climate change. But it only takes one of us to be right for the IPCC’s anthropogenic global warming (AGW) house of cards to collapse.
As I like to say, taking measurements of the climate system is much easier than figuring out what those measurements mean in terms of cause and effect. Generally speaking, it’s not the warming that is in dispute…it’s the cause of the warming.
If you disagree with my views on something, please don’t flame me. Chances are, I’ve already heard your point of view; very seldom am I provided with new evidence I haven’t already taken into account.
1) Are Global Temperatures Rising Now? There is no way to know, because natural year-to-year variability in global temperature is so large, with warming and cooling occurring all the time. What we can say is that surface and lower atmospheric temperature have risen in the last 30 to 50 years, with most of that warming in the Northern Hemisphere. Also, the magnitude of recent warming is somewhat uncertain, due to problems in making long-term temperature measurements with thermometers without those measurements being corrupted by a variety of non-climate effects. But there is no way to know if temperatures are continuing to rise now…we only see warming (or cooling) in the rearview mirror, when we look back in time.
2) Why Do Some Scientists Say It’s Cooling, while Others Say the Warming is Even Accelerating? Since there is so much year-to-year (and even decade-to-decade) variability in global average temperatures, whether it has warmed or cooled depends upon how far back you look in time. For instance, over the last 100 years, there was an overall warming which was stronger toward the end of the 20th Century. This is why some say “warming is accelerating”. But if we look at a shorter, more recent period of time, say since the record warm year of 1998, one could say that it has cooled in the last 10-12 years. But, as I mentioned above, neither of these can tell us anything about whether warming is happening “now”, or will happen in the future.
3) Haven’t Global Temperatures Risen Before? Yes. In the longer term, say hundreds to thousands of years, there is considerable indirect, proxy evidence (not from thermometers) of both warming and cooling. Since humankind can’t be responsible for these early events is evidence that nature can cause warming and cooling. If that is the case, it then opens up the possibility that some (or most) of the warming in the last 50 years has been natural, too. While many geologists like to point to much larger temperature changes are believed to have occurred over millions of years, I am unconvinced that this tells us anything of use for understanding how humans might influence climate on time scales of 10 to 100 years.
4) But Didn’t the “Hockey Stick” Show Recent Warming to be Unprecedented? The “hockey Stick” reconstructions of temperature variations over the last 1 to 2 thousand years have been a huge source of controversy. The hockey stick was previously used by the IPCC as a veritable poster child for anthropogenic warming, since it seemed to indicate there have been no substantial temperature changes over the last 1,000 to 2,000 years until humans got involved in the 20th Century. The various versions of the hockey stick were based upon limited amounts of temperature proxy evidence — primarily tree rings — and involved questionable statistical methods. In contrast, I think the bulk of the proxy evidence supports the view that it was at least as warm during the Medieval Warm Period, around 1000 AD. The very fact that recent tree ring data erroneously suggests cooling in the last 50 years, when in fact there has been warming, should be a warning flag about using tree ring data for figuring out how warm it was 1,000 years ago. But without actual thermometer data, we will never know for sure.
5) Isn’t the Melting of Arctic Sea Ice Evidence of Warming? Warming, yes…manmade warming, no. Arctic sea ice naturally melts back every summer, but that meltback was observed to reach a peak in 2007. But we have relatively accurate, satellite-based measurements of Arctic (and Antarctic) sea ice only since 1979. It is entirely possible that late summer Arctic Sea ice cover was just as low in the 1920s or 1930s, a period when Arctic thermometer data suggests it was just as warm. Unfortunately, there is no way to know, because we did not have satellites back then. Interestingly, Antarctic sea ice has been growing nearly as fast as Arctic ice has been melting over the last 30+ years.
6) What about rising sea levels? I must confess, I don’t pay much attention to the sea level issue. I will say that, to the extent that warming occurs, sea levels can be expected to also rise to some extent. The rise is partly due to thermal expansion of the water, and partly due to melting or shedding of land-locked ice (the Greenland and Antarctic ice sheets, and glaciers). But this says nothing about whether or not humans are the cause of that warming. Since there is evidence that glacier retreat and sea level rise started well before humans can be blamed, causation is — once again — a major source of uncertainty.
7) Is Increasing CO2 Even Capable of Causing Warming? There are some very intelligent people out there who claim that adding more carbon dioxide to the atmosphere can’t cause warming anyway. They claim things like, “the atmospheric CO2 absorption bands are already saturated”, or something else very technical. [And for those more technically-minded persons, yes, I agree that the effective radiating temperature of the Earth in the infrared is determined by how much sunlight is absorbed by the Earth. But that doesn’t mean the lower atmosphere cannot warm from adding more greenhouse gases, because at the same time they also cool the upper atmosphere]. While it is true that most of the CO2-caused warming in the atmosphere was there before humans ever started burning coal and driving SUVs, this is all taken into account by computerized climate models that predict global warming. Adding more “should” cause warming, with the magnitude of that warming being the real question. But I’m still open to the possibility that a major error has been made on this fundamental point. Stranger things have happened in science before.
8 ) Is Atmospheric CO2 Increasing? Yes, and most strongly in the last 50 years…which is why “most” climate researchers think the CO2 rise is the cause of the warming. Our site measurements of CO2 increase from around the world are possibly the most accurate long-term, climate-related, measurements in existence.
9) Are Humans Responsible for the CO2 Rise? While there are short-term (year-to-year) fluctuations in the atmospheric CO2 concentration due to natural causes, especially El Nino and La Nina, I currently believe that most of the long-term increase is probably due to our use of fossil fuels. But from what I can tell, the supposed “proof” of humans being the source of increasing CO2 — a change in the atmospheric concentration of the carbon isotope C13 — would also be consistent with a natural, biological source. The current atmospheric CO2 level is about 390 parts per million by volume, up from a pre-industrial level estimated to be around 270 ppm…maybe less. CO2 levels can be much higher in cities, and in buildings with people in them.
10) But Aren’t Natural CO2 Emissions About 20 Times the Human Emissions? Yes, but nature is believed to absorb CO2 at about the same rate it is produced. You can think of the reservoir of atmospheric CO2 as being like a giant container of water, with nature pumping in a steady stream into the bottom of the container (atmosphere) in some places, sucking out about the same amount in other places, and then humans causing a steady drip-drip-drip into the container. Significantly, about 50% of what we produce is sucked out of the atmosphere by nature, mostly through photosynthesis. Nature loves the stuff. CO2 is the elixir of life on Earth. Imagine the howls of protest there would be if we were destroying atmospheric CO2, rather than creating more of it.
11) Is Rising CO2 the Cause of Recent Warming? While this is theoretically possible, I think it is more likely that the warming is mostly natural. At the very least, we have no way of determining what proportion is natural versus human-caused.
12) Why Do Most Scientists Believe CO2 is Responsible for the Warming? Because (as they have told me) they can’t think of anything else that might have caused it. Significantly, it’s not that there is evidence nature can’t be the cause, but a lack of sufficiently accurate measurements to determine if nature is the cause. This is a hugely important distinction, and one the public and policymakers have been misled on by the IPCC.
13) If Not Humans, What could Have Caused Recent Warming? This is one of my areas of research. I believe that natural changes in the amount of sunlight being absorbed by the Earth — due to natural changes in cloud cover — are responsible for most of the warming. Whether that is the specific mechanism or not, I advance the minority view that the climate system can change all by itself. Climate change does not require an “external” source of forcing, such as a change in the sun.
14) So, What Could Cause Natural Cloud Changes? I think small, long-term changes in atmospheric and oceanic flow patterns can cause ~1% changes in how much sunlight is let in by clouds to warm the Earth. This is all that is required to cause global warming or cooling. Unfortunately, we do not have sufficiently accurate cloud measurements to determine whether this is the primary cause of warming in the last 30 to 50 years.
15) How Significant is the Climategate Release of E-Mails? While Climategate does not, by itself, invalidate the IPCC’s case that global warming has happened, or that humans are the primary cause of that warming, it DOES illustrate something I emphasized in my first book, “Climate Confusion”: climate researchers are human, and prone to bias.
16) Why Would Bias in Climate Research be Important? I thought Scientists Just Follow the Data Where It Leads Them When researchers approach a problem, their pre-conceived notions often guide them. It’s not that the IPCC’s claim that humans cause global warming is somehow untenable or impossible, it’s that political and financial pressures have resulted in the IPCC almost totally ignoring alternative explanations for that warming.
17) How Important Is “Scientific Consensus” in Climate Research? In the case of global warming, it is nearly worthless. The climate system is so complex that the vast majority of climate scientists — usually experts in variety of specialized fields — assume there are more knowledgeable scientists, and they are just supporting the opinions of their colleagues. And among that small group of most knowledgeable experts, there is a considerable element of groupthink, herd mentality, peer pressure, political pressure, support of certain energy policies, and desire to Save the Earth — whether it needs to be saved or not.
18) How Important are Computerized Climate Models? I consider climate models as being our best way of exploring cause and effect in the climate system. It is really easy to be wrong in this business, and unless you can demonstrate causation with numbers in equations, you are stuck with scientists trying to persuade one another by waving their hands. Unfortunately, there is no guarantee that climate models will ever produce a useful prediction of the future. Nevertheless, we must use them, and we learn a lot from them. My biggest concern is that models have been used almost exclusively for supporting the claim that humans cause global warming, rather than for exploring alternative hypotheses — e.g. natural climate variations — as possible causes of that warming.
19) What Do I Predict for Global Temperature Changes in the Future? I tend to shy away from long-term predictions, because there are still so many uncertainties. When pressed, though, I tend to say that I think cooling in our future is just as real a possibility as warming. Of course, a third possibility is relatively steady temperatures, without significant long-term warming or cooling. Keep in mind that, while you will find out tomorrow whether your favorite weather forecaster is right or wrong, no one will remember 50 years from now a scientist today wrongly predicting we will all die from heat stroke by 2060.
Climate researchers do not know nearly as much about the causes of climate change as they profess. We have a pretty good understanding of how the climate system works on average…but the reasons for small, long-term changes in climate system are still extremely uncertain.
The total amount of CO2 humans have added to the atmosphere in the last 100 years has upset the radiative energy budget of the Earth by only 1%. How the climate system responds to that small “poke” is very uncertain. The IPCC says there will be strong warming, with cloud changes making the warming worse. I claim there will be weak warming, with cloud changes acting to reduce the influence of that 1% change. The difference between these two outcomes is whether cloud feedbacks are positive (the IPCC view), or negative (the view I and a minority of others have).
So far, neither side has been able to prove their case. That uncertainty even exists on this core issue is not appreciated by many scientists!
Again I will emphasize, some very smart people who consider themselves skeptics will disagree with some of my views stated above, particularly when it involves explanations for what has caused warming, and what has caused atmospheric CO2 to increase.
Unlike the global marching army of climate researchers the IPCC has enlisted, we do not walk in lockstep. We are willing to admit, “we don’t really know”, rather than mislead people with phrases like, “the warming we see is consistent with an increase in CO2”, and then have the public think that means, “we have determined, through our extensive research into all the possibilities, that the warming cannot be due to anything but CO2”.
Skeptics advancing alternative explanations (hypotheses) for climate variability represent the way the researcher community used to operate, before politics, policy outcomes, and billions of dollars got involved.
