George C. Marshall Institute

George C. Marshall Institute (GMI)


The George C. Marshall Institute (GMI) was founded in 1984 by William Nierenberg, Frederick Seitz and Robert Jastrow as a “nonprofit 501(c)(3) corporation to conduct technical assessments of scientific issues with an impact on public policy.” [1]

In 1989, at the same time the George C. Marshall Institute initiated its “Climate Change Policy Program,” the GMI also released a report arguing that “cyclical variations in the intensity of the sun would offset any climate change associated with elevated greenhouse gases.” Although it was refuted by the IPCC, the report was used by the Bush Sr. Administration to argue for a more lenient climate change policy. [2]

GMI has since published a series of reports and articles that attempt to discredit mainstream climate science and undermine climate change legislation such as the Kyoto Protocol.

The Marshall Institute's “Climate Change Policy” program was started in 1989 as a “critical examination of the scientific basis for global climate change policy.” Notably, “A major component of this effort is communicating the findings to policy makers, the media and the public policy community.” [3]

In a 2009 essay, former Executive Director Matthew B. Crawford had this to say about his initial experience with the Marshall Institute (emphasis added):

“… certain perversities became apparent as I settled into the job. It sometimes required me to reason backward, from desired conclusion to suitable premise. The organization had taken certain positions, and there were some facts it was more fond of than others. As its figurehead, I was making arguments I didn't fully buy myself. Further, my boss seemed intent on retraining me according to a certain cognitive style — that of the corporate world, from which he had recently come. This style demanded that I project an image of rationality but not indulge too much in actual reasoning.” [4]

Newsweek has described the George C. Marshall Institute as a “central cog in the denial machine,” and Naomi Oreskes has said that the Institute has lobbied politically to create a false perception of scientific uncertainty over the negative effects of second-hand smoke, the carcinogenic nature of tobacco smoking, the existence of acid rain, and on the evidence between CFCs and ozone depletion. [5 [22]

Stance on Climate Change

“There remains considerable uncertainty as to how much the climate has varied regionally and globally on the decades-to-centuries timescale, or what caused those changes.  Yet we need to know how natural climate fluctuations are caused in order to determine to what extent human activities have affected the climate system.” [6]

“Human activity, such as the burning of fossil fuels to power our homes and businesses and changes to the land caused by the rise of modern cities and expanded agriculture, undoubtedly affect the global environment. It is the extent of that effect and how it relates to changes in the modern climate which is the subject of current scientific debate. […] Many of the temperature data and computer models used to predict climate change are themselves as uncertain as are our understanding of important interactions in the natural climate.” [7]

Initially, the George Marshall Institute (GMI) had restricted its funding sources to private foundations and individual donors to avoid conflict of interest but in the late nineties, the Institute decided that “the limitation we had placed on our sources of funding no longer made sense,” and that “From now on the Marshall Institute will accept grants for general program support from corporate foundations and in some cases directly from corporations.” Its first-ever corporate donation was from the Exxon Education Foundation. [11]

July 7 - 9, 2014

The George C. Marshall Institute is listed as an official Cosponsor of the Heartland Institute's Ninth International Conference on Climate Change (ICCC7) in Las Vegas, Nevada.  [21]

July, 2014

In a live interview on CNBC, William Happer, chairman of the Marshall Institute, stated that the “demonization of carbon dioxide is just like the demonization of the poor Jews under Hitler.” Co-host Andrew Ross Sorkin challenged Happer for “not believ[ing] in climate change,” to which Happer responded by telling Sorkin to “shut up.”  Media Matters also points out that Happer has “no peer-reviewed research on climate change.” [23], [24][25]

View the video below:

May 8, 2013

The Wall Street Journal published an opinion peace by Harrison H. Schmitt and the George C. Marshall Institute's William Happer titled “In Defense of Carbon Dioxide,” in which the authors said: “[T]he conventional wisdom about carbon dioxide is that it is a dangerous pollutant. That’s simply not the case. Contrary to what some would have us believe, increased carbon dioxide in the atmosphere will benefit the increasing population on the planet by increasing agricultural productivity.” [26]

May 21 - 23, 2012

The George C. Marshall Institute is listed as an official co-sponsor (PDF) of the Heartland Institute's Seventh International Conference on Climate Change (ICCC7). [27]

November, 2011

The George C. Marshall Institute released a study that concluded “Global warming is unlikely to damage U.S. national security, but expensive programs implemented to reduce greenhouse gas emissions will weaken the nation’s economy and military,” as reported by The Heartland Institute. [28]
According to Marshall Institute CEO William O-Keefe, even if global warming occurs, “The impacts of weather events or climate change in the developing world are not caused by developed world carbon emissions. They are caused primarily by extreme poverty which is the result of exploitation by dictators, and the lack of economic and personal freedom, the rule of law, property rights, and access to commercial energy. Solving the problem of poverty in these countries would provide them the capacity and resilience to deal with whatever climate exists in the future.” 
June 30 - July 1, 2011
The George C. Marshall Institute was an official Cosponsor (PDF) of the Heartland Institute's Sixth International Conference on Climate Change (ICCC6) in Washington, DC. [29]
DeSmogBlog concluded that 17 of the 43 sponsors of the Heartland Institute's Sixth International Conference on Climate Change, including the Heartland Institute itself, had collectively received over $46 million from either Scaife Foundations, Koch Foundations, or ExxonMobil. [30]
May 20, 2010
Will Happer, as chair of the George C. Marshall Institute, testified before Rep. Ed Markey’s Select committee as the sole GOP witness arguing against the global warming consensus.  [31]
The hearing reported to “explore scientists' ability to present data and information that can guide global warming solutions in a sometimes fierce political landscape.” [32]
May 16 - 18, 2010
The George C. Marshall Institute was an official Cosponsor (PDF) of the Heartland Institute's Fourth International Conference on Climate Change (ICCC4) in Chicago, ILThe conference's theme was “Reconsidering the Science and Economics,” and its purpose was “the same as it was for the first three events: to build momentum and public awareness of the global warming 'realism' movement.” [33]
DeSmogBlog concluded 19 of the 65 sponsors (including Heartland itself) had received a total of over $40 million in funding since 1985 from ExxonMobil (who funded 13 of the organizations), and/or Koch Industries family foundations (funded 10 organizations) and/or the Scaife family foundations (funded 10 organizations). [34]

June 2, 2009

The George C. Marshall Institute was an official Cosponsor of the Heartland Institute's Third International Conference on Climate Change (ICCC3) in Washington, DC. [35]

The conference's theme was “Climate Change: Scientific Debate and Economic Analysis,” to reflect Heartland's belief that that “scientific debate is not over.” The conference set out to “call attention to widespread dissent to the asserted 'consensus' on various aspects of climate change and global warming.” [36]

March 8 - 10, 2009

The George C. Marshall Institute was an official Cosponsor of the Heartland Institute's Second International Conference on Climate Change (ICCC2) in New York. [37]

DeSmogBlog researched the funding behind Heartland's Second International Conference on Climate Change and found that sponsor organizations had received over $47 million in funding from energy companies and right-wing foundations, with 78% of that total coming from Scaife Family foundations.  [38]

February 25, 2009

George C. Marshall Institute Chair William Happer testified on climate change (PDF) before the U.S. Senate Environment and Public Works Committee.

In his opening statement, Happer admits “I am not a climatologist, but I don’t think any of the other witnesses are either.” He then goes on to state that “I believe that the increase of CO2 is not a cause for alarm and will be good for mankind,” comparing policies designed to reduce emissions to the U.S. prohibition of alcohol.

Happer uses other common skeptic arguments, saying that “The current warming also seems to be due mostly to natural causes, not to increasing levels of carbon dioxide,” that “The climate has changed many times in the past,” that “IPCC summaries for policy makers are not dispassionate statements of the facts of climate change,” that “There is a delay between a temperature increase and a CO2 increase of about 800 years,” and, finally, “that moderate warming is an overall benefit to mankind because of higher agricultural yields and many other reasons.” [39]

March 2 - 4, 2008

The George C. Marshall Institute was an official Cosponsor of the Heartland Institute's First International Conference on Climate Change (ICCC1). The Conference was titled “Global Warming: Truth or Swindle.” [40]

May, 2006

As reported at PolluterWatch, an anonymous source sent Greenpeace a copy of an invitation, agenda and attendees list (PDF) for a May 2006 meeting organized by the Heartland Institute and hosted at the DCI Group offices “to discuss public policy challenges related to the Clean Air Act.” The George C. Marshall Institute was one of the organizations invited to the session. [41][42]

The only corporation represented at the meeting was Exxon Mobil. Exxon representatives gave two presentations over the course of the full day meeting. Six ExxonMobil staff are listed as invited guests. Two DCI – Tech Central Station representatives are named on the invitees list, along with a note “plus DCI field officers and staff.” 

December 14, 2005

The Marshall Institute published the book Shattered Consensus: The True State of Global Warming, edited by climate change skeptic Patrick J. Michaels.

The book contains essays by skeptics Sallie L. Baliunas, Robert C. Balling Jr., Randall S. Cerveny, John Christy, Robert E. Davis, Oliver W. Frauenfeld, Ross McKitrick, Patrick J. Michaels, Eric S. Posmentier, and Willie Soon. [43]

December 12, 2004

According to the Heartland Institute, the forum “reviewed application of the precautionary principle to new biotechnology products, old restrictions on DDT, and new restrictions on a tried and true herbicide, paraquat.”

November 16, 2004

The GMI issued a press release regarding the Arctic Climate Impact Assessment (ACIA) by the eight-nation Arctic Council.

GMI said that “This report makes numerous claims about climate change on arctic regions. Most of its claims are based on invalidated climate models and scenarios developed by the Intergovernmental Panel on Climate Change (IPCC) that bear little resemblance to reality and how the future is likely to evolve. And indeed, some of its claims about sea ice and ‘alarming’ warming are contradicted by other peer reviewed research and data.” [45]

April 12, 2004

The Marshall Institute sponsored a “Washington Roundtable on Science and Public Policy” where climate change skeptic David Legates presented on the subject of “Global Warming and the Hydrological Cycle “(PDF).

Legates suggested that climate change would be unlikely to increase extreme weather conditions, saying “… in many cases, the argument might be that in a warmer world, we will see fewer, not more, extreme events. This is actually good news, because it is extremes that cause the most economic damage and cause the most deaths.” [46]


The George C. Marshal Institute co-published a document titled the “Oregon Petition” along with the Oregon Institute of Science and Medicine. The petition claims to have collected 17,000 signatories that argue against the existence of man-made climate change and has been repeatedly used by climate change skeptics as proof that there is no scientific consensus on climate change. [47], [48]

As reported in the Huffington Post, along with the petition there was a cover letter from Dr. Fred Seitz, a prominent climate change denier (and tobacco scientist), who over 30 years ago was the president of the National Academy of Science. Also attached to the petition was what appeared to be a “research paper” titled: Environmental Effects of Increased Atmospheric Carbon Dioxide. [49]

The petition and the documents included were all made to look like official papers from the prestigious National Academy of Science even though they were not affiliated with the production in any way.

The petition was so misleading that the National Academy issued a news release stating that “The petition project was a deliberate attempt to mislead scientists and to rally them in an attempt to undermine support for the Kyoto Protocol. The petition was not based on a review of the science of global climate change, nor were its signers experts in the field of climate science.” [50] 

The documents included with the petition had been authored by climate skeptics Art Robinson, Sallie Baliunas, and Willie Soon.
