The Great Global Warming Swindle <=SEP=> The Great Global Warming Swindle is a polemical documentary film that suggests that the scientific opinion on climate change is influenced by funding and political factors , and questions whether scientific consensus on global warming exists . The program was formally criticised by Ofcom , the UK broadcasting regulatory agency , which upheld complaints of misrepresentation made by David King .   The film , made by British television producer Martin Durkin , presents scientists , economists , politicians , writers , and others who dispute the scientific consensus regarding anthropogenic global warming . The programme 's publicity materials assert that man-made global warming is `` a lie '' and `` the biggest scam of modern times . '' Its original working title was `` Apocalypse my arse '' , but the title The Great Global Warming Swindle was later adopted as an allusion to the 1980 mockumentary The Great Rock 'n' Roll Swindle about British punk band the Sex Pistols .   The UK 's Channel 4 premiered the documentary on 8 March 2007 . The channel described the film as `` a polemic that drew together the well-documented views of a number of respected scientists to reach the same conclusions . This is a controversial film but we feel that it is important that all sides of the debate are aired . '' According to Hamish Mykura , Channel 4 's head of documentaries , the film was commissioned `` to present the viewpoint of the small minority of scientists who do not believe global warming is caused by anthropogenic production of carbon dioxide . ''   Although the documentary was welcomed by global warming sceptics , it was criticised by scientific organisations and individual scientists ( including one of the scientists interviewed in the film and one whose research was used to support the film 's claims ) . The film 's critics argued that it had misused and fabricated data , relied on out-of-date research , employed misleading arguments , and misrepresented the position of the Intergovernmental Panel on Climate Change . Later broadcasts corrected three errors in the original film .

Fred Singer <=SEP=> Siegfried Fred Singer ( born September 27 , 1924 ) is an Austrian-born American physicist and emeritus professor of environmental science at the University of Virginia . Singer trained as an atmospheric physicist and is known for his work in space research , atmospheric pollution , rocket and satellite technology , his questioning of the link between UV-B and melanoma rates , and that between CFCs and stratospheric ozone loss , his public downplaying of the health risks of passive smoking , and as an advocate for climate change denial . He is the author or editor of several books including Global Effects of Environmental Pollution ( 1970 ) , The Ocean in Human Affairs ( 1989 ) , Global Climate Change ( 1989 ) , The Greenhouse Debate Continued ( 1992 ) , and Hot Talk , Cold Science ( 1997 ) . He has also co-authored Unstoppable Global Warming : Every 1,500 Years ( 2007 ) with Dennis Avery , and Climate Change Reconsidered ( 2009 ) with Craig Idso .   Singer has had a varied career , serving in the armed forces , government , and academia . He designed mines for the U.S. Navy during World War II , before obtaining his Ph.D. in physics from Princeton University in 1948 and working as a scientific liaison officer in the U.S. Embassy in London . He became a leading figure in early space research , was involved in the development of earth observation satellites , and in 1962 established the National Weather Bureau 's Satellite Service Center . He was the founding dean of the University of Miami School of Environmental and Planetary Sciences in 1964 , and held several government positions , including deputy assistant administrator for the Environmental Protection Agency , and chief scientist for the Department of Transportation . He held a professorship with the University of Virginia from 1971 until 1994 , and with George Mason University until 2000 .   In 1990 Singer founded the Science & Environmental Policy Project , and in 2006 was named by the Canadian Broadcasting Corporation as one of a minority of scientists said to be creating a stand-off on a consensus on climate change . Singer argues there is no evidence that global warming is attributable to human-caused increases in atmospheric carbon dioxide , and that humanity would benefit if temperatures do rise .  He is an opponent of the Kyoto Protocol , and has claimed that climate models are neither based on reality nor evidence . Singer has been accused of rejecting peer-reviewed and independently confirmed scientific evidence in his claims concerning public health and environmental issues .
