Environmental skepticism is the belief that statements by environmentalists, and the environmental scientists who support them, are false or exaggerated. The term is also applied to those who are critical of environmentalism in general. It can additionally be defined as doubt about the authenticity or severity of environmental degradation. Environmental skepticism is closely linked with anti-environmentalism and climate change denial. Environmental skepticism can also be the result of cultural and lived experiences.
Siegfried Fred Singer was an Austrian-born American physicist and emeritus professor of environmental science at the University of Virginia, trained as an atmospheric physicist. He was known for rejecting the scientific consensus on several issues, including climate change, the connection between UV-B exposure and melanoma rates, stratospheric ozone loss being caused by chlorofluoro compounds, often used as refrigerants, and the health risks of passive smoking.
Patrick J. Michaels was an American agricultural climatologist. Michaels was a senior fellow in environmental studies at the Cato Institute until 2019. Until 2007, he was research professor of environmental sciences at the University of Virginia, where he had worked from 1980.
Stephen McIntyre is a Canadian mining exploration company director, a former minerals prospector and semi-retired mining consultant whose work has included statistical analysis. He is the founder and editor of Climate Audit, a blog which analyses and discusses climate data. He is a critic of the temperature record of the past 1000 years and the data quality of NASA's Goddard Institute for Space Studies. He has made statistical critiques, with economist Ross McKitrick, of the hockey stick graph which shows that the increase in late 20th century global temperatures is unprecedented in the past 1,000 years.
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 IPCC Third Assessment Report (TAR), Climate Change 2001, is an assessment of available scientific and socio-economic information on climate change by the IPCC. Statements of the IPCC or information from the TAR were often used as a reference showing a scientific consensus on the subject of global warming. The Third Assessment Report (TAR) was completed in 2001 and consists of four reports, three of them from its Working Groups: Working Group I: The Scientific Basis; Working Group II: Impacts, Adaptation and Vulnerability; Working Group III: Mitigation; Synthesis Report. A number of the TAR's conclusions are given quantitative estimates of how probable it is that they are correct, e.g., greater than 66% probability of being correct. These are "Bayesian" probabilities, which are based on an expert assessment of all the available evidence.
Richard A. Muller is an American physicist and emeritus professor of physics at the University of California, Berkeley. He was also a faculty senior scientist at the Lawrence Berkeley National Laboratory. In early 2010, Muller and his daughter Elizabeth Muller founded the group Berkeley Earth, an independent 501(c)(3) non-profit aimed at addressing some of the major concerns of the climate change skeptics, in particular the global surface temperature record. In 2016, Richard and Elizabeth Muller co-founded Deep Isolation, a private company seeking to dispose of nuclear waste in deep boreholes.
William Dawbney Nordhaus is an American economist. He was a Sterling Professor of Economics at Yale University, best known for his work in economic modeling and climate change, and a co-recipient of the 2018 Nobel Memorial Prize in Economic Sciences. Nordhaus received the prize "for integrating climate change into long-run macroeconomic analysis".
Fraser Barry Cooper is a Canadian political scientist at the University of Calgary. Before coming to Calgary, he taught at Bishop's University (1968–1970), McGill University, and York University (1970–1981). The winner of a Killam Research Fellowship, he is a fellow of the Royal Society of Canada. In 1991, Cooper wrote Action into Nature: An Essay on the Meaning of Technology and he co-authored Deconfederation: Canada without Quebec, in which he argued that Canada would benefit from Quebec separation. He is also the author of the 1999 publication Eric Voegelin and the Foundations of Modern Political Science.
Hockey stick graphs present the global or hemispherical mean temperature record of the past 500 to 2000 years as shown by quantitative climate reconstructions based on climate proxy records. These reconstructions have consistently shown a slow long term cooling trend changing into relatively rapid warming in the 20th century, with the instrumental temperature record by 2000 exceeding earlier temperatures.
Richard George Lipsey, is a Canadian academic and economist. He is best known for his work on the economics of the second-best, a theory that demonstrated that piecemeal establishing of individual first best conditions would not necessarily raise welfare in a situation in which all first best conditions could not be satisfied, an article that he co-authored with Kelvin Lancaster. He is currently Professor Emeritus of Economics at Simon Fraser University.
Taken By Storm: The Troubled Science, Policy and Politics of Global Warming is a 2002 book about the global warming controversy by Christopher Essex and Ross McKitrick. The authors argue that politicians and others claim far more certainty than is justified by the science. The authors also argue that public policy discussions have abandoned science and resorted to ad hominem attacks.
Richard S. J. Tol is a professor of economics at the University of Sussex. He is also professor of the economics of climate change at the Vrije Universiteit Amsterdam. He is a member of the Academia Europaea.
Mark Kenneth Jaccard is a Canadian energy economist and author. He develops and applies models that assess sustainability policies for energy and material. Jaccard is a professor of sustainable energy in the School of Resource and Environmental Management (REM) at Simon Fraser University.
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.
The Hockey Stick Illusion: Climategate and the Corruption of Science is a book written by Andrew Montford and published by Stacey International in 2010, which promotes climate change denial.
The Wegman Report was prepared in 2006 by three statisticians led by Edward Wegman at the request of Rep. Joe Barton of the United States House Committee on Energy and Commerce to validate criticisms made by Stephen McIntyre and Ross McKitrick of reconstructions of the temperature record of the past 1000 years, in particular the reconstructions by Mann, Bradley and Hughes of what had been dubbed the hockey stick graph.
Timothy Francis Ball was a British-born Canadian public speaker and writer who was a professor in the Department of Geography at the University of Winnipeg from 1971 until his retirement in 1996. Subsequently Ball became active in promoting rejection of the scientific consensus on global warming, giving public talks and writing opinion pieces and letters to the editor for Canadian newspapers.
