The George C. Marshall Institute (GMI) was a nonprofit conservative think tank in the United States. It was established in 1984 with a focus on science and public policy issues and had an initial focus in defense policy. Starting in the late 1980s, the institute advocated for views in line with environmental skepticism, most notably climate change denial. The think tank received extensive financial support from the fossil fuel industry.
The Scientific Alliance is a UK-based organization that claims to promote open-minded debate on scientific matters and science policy, including biotechnology, genetically modified food, energy and climate change. Its stated aim is to "bring together both scientists and non-scientists committed to rational discussion and debate on the challenges facing the environment today." In the scientific literature it is regarded as "a UK-based lobby group which challenges the scientific consensus on climate change".
The Committee for a Constructive Tomorrow (CFACT) is a US-based 501(c)(3) nonprofit organization founded in 1985 that advocates for free-market solutions to environmental issues. According to its mission statement, CFACT also seeks to protect private property rights, promote economic policies that reduce pollution and protect wildlife, and provide an "alternative voice on issues of environment and development".
Doctors for Disaster Preparedness (DDP) is a 501(c)(3) non-profit organization located in Tucson, Arizona. The group is closely affiliated with the American Association of Physicians and Surgeons, a politically conservative nonprofit association advocating numerous discredited hypotheses including AIDS denialism. It is run by Arizona physician Jane Orient.
The Great Global Warming Swindle is a 2007 British polemical documentary film directed by Martin Durkin. The film denies the scientific consensus about the reality and causes of climate change, justifying this by suggesting that climatology is influenced by funding and political factors. The program was formally criticised by Ofcom, the UK broadcasting regulatory agency, which ruled the film failed to uphold due impartiality and upheld complaints of misrepresentation made by David King, who appeared in the film.
Climate change denial is a form of science denial characterized by rejecting, refusing to acknowledge, disputing, or fighting the scientific consensus on climate change. Those promoting denial commonly use rhetorical tactics to give the appearance of a scientific controversy where there is none. Climate change denial includes unreasonable doubts about the extent to which climate change is caused by humans, its effects on nature and human society, and the potential of adaptation to global warming by human actions. To a lesser extent, climate change denial can also be implicit when people accept the science but fail to reconcile it with their belief or action. Several studies have analyzed these positions as forms of denialism, pseudoscience, or propaganda.
House of Numbers: Anatomy of an Epidemic is a 2009 film directed, produced, and hosted by Brent Leung and described by him as an objective examination of the idea that HIV causes AIDS. The film argues that human immunodeficiency virus (HIV) is harmless and does not cause acquired immune deficiency syndrome (AIDS), a position known as AIDS denialism. The film's claims of impartiality have been widely rejected by scientists, and the film's claims about HIV and AIDS have been dismissed as pseudoscience and conspiracy theory masquerading as even-handed examination.
The Cornwall Alliance for the Stewardship of Creation is a conservative Christian public policy group that claims that a free-market approach to care for the environment is sufficient, and is critical of much of the current environmental movement. The Alliance is "engaged in a wide range of antienvironmental activities" and denies man-made global warming.
Heaven and Earth: Global Warming – The Missing Science is a popular science book published in 2009 and written by Australian geologist, professor of mining geology at the University of Adelaide, and mining company director Ian Plimer. It disputes the scientific consensus on climate change, including the view that global warming is "very likely due to the observed increase in anthropogenic (man-made) greenhouse gas concentrations" and asserts that the debate is being driven by what the author regards as irrational and unscientific elements.
Judith A. Curry is an American climatologist and former chair of the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology. Her research interests include hurricanes, remote sensing, atmospheric modeling, polar climates, air-sea interactions, climate models, and the use of unmanned aerial vehicles for atmospheric research. She was a member of the National Research Council's Climate Research Committee, published over a hundred scientific papers, and co-edited several major works. Curry retired from academia in 2017 at age 63, coinciding with her public climate change skepticism.
Merchants of Doubt: How a Handful of Scientists Obscured the Truth on Issues from Tobacco Smoke to Global Warming is a 2010 non-fiction book by American historians of science Naomi Oreskes and Erik M. Conway. It identifies parallels between the global warming controversy and earlier controversies over tobacco smoking, acid rain, DDT, and the hole in the ozone layer. Oreskes and Conway write that in each case "keeping the controversy alive" by spreading doubt and confusion after a scientific consensus had been reached was the basic strategy of those opposing action. In particular, they show that Fred Seitz, Fred Singer, and a few other contrarian scientists joined forces with conservative think tanks and private corporations to challenge the scientific consensus on many contemporary issues.
Joanne Nova is an Australian writer, blogger, and speaker. Born Joanne Codling, she adopted the stage name "Nova" in 1998 when she was preparing to host a children's television program. She is prominent for promoting climate change denial.

Stephan Lewandowsky is an Australian psychologist. He has worked in both the United States and Australia, and is currently based at the University of Bristol, UK, where he is the chair of cognitive psychology at the School of Psychological Science. His research, which originally pertained to computer simulations of people's decision-making processes, recently has focused on the public's understanding of science and why people often embrace beliefs that are sharply at odds with scientific evidence.
Merchants of Doubt is a 2014 American documentary film directed by Robert Kenner and inspired by the 2010 book of the same name by Naomi Oreskes and Erik M. Conway. The film traces the use of public relations tactics that were originally developed by the tobacco industry to protect their business from research indicating health risks from smoking. The most prominent of these tactics is the cultivation of scientists and others who successfully cast doubt on scientific results. Using a professional magician, the film explores the analogy between these tactics and the methods used by magicians to distract their audiences from observing how illusions are performed. For the tobacco industry, the tactics successfully delayed government regulation until long after the establishment of scientific consensus about the health risks from smoking. As its second example, the film describes how manufacturers of flame retardants worked to protect their sales after toxic effects of the retardants were reported in the scientific literature. The central concern of the film is the ongoing use of these tactics to forestall governmental action to regulate greenhouse gas emissions in response to the risks of global climate change.
The CO2 Coalition is a 501(c)(3) nonprofit advocacy organization in the United States founded in 2015. Its climate change denialist claims conflict with the scientific consensus on climate change.
