The Great Global Warming Swindle

The Great Global Warming Swindle is a documentary film that argues against the scientific consensus that global warming is "very likely due to the observed increase in anthropogenic (man-made) greenhouse gas concentrations". It has been described by both its original broadcaster Channel 4 and the British regulator Ofcom as "a polemic".

The film, made by British television producer Martin Durkin, showcases scientists, economists, politicians, writers, and others who are sceptical about the scientific theory of 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 a reference to The Great Rock 'n' Roll Swindle, a mockumentary 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 heavily by many scientific organisations and individual scientists (including two of the film's contributors). The film's critics argued that it had misused and fabricated data, relied on out-of-date research, employed misleading arguments, and misrepresented the position of the Intergovernmental Panel on Climate Change. Channel 4 and Wag TV (the production company) accepted some of the criticism, correcting a few errors in subsequent releases. However according to Bob Ward (former spokesman for the Royal Society), this still left five out of seven of the errors and misleading arguments which had been previously attacked by him and 36 other scientists in an open letter.

The British broadcasting regulator, the Office of Communications (Ofcom), received 265 complaints about the programme, one of which was a 176-page detailed complaint co-authored by a group of scientists. Ofcom used this complaint in its deliberation, and delivered its ruling on 21 July 2008. It ruled that the programme had unfairly treated Sir David King, the IPCC and Professor Carl Wunsch. Ofcom also found that part 5 of the programme (the 'political' part) had breached several parts of the Broadcasting Code regarding impartiality. Ofcom said that the rules on impartiality did not apply to the scientific arguments in parts 1-4, because global warming caused by human activity was a settled fact: "In this respect it could be said that the discussion about the causes of global warming was to a very great extent settled by the date of broadcast ( 8 March 2007 ). In Ofcom’s view the link between human activity and global warming also became similarly settled before March 2007.Having reached this view, it follows that the rules relating to the preservation of due impartiality did not apply to these parts.". Regarding the programme's accuracy, Ofcom noted that in its role as regulator it: "had to ascertain – not whether the programme was accurate - but whether it materially misled the audience." On this basis Ofcom ruled that: "On balance it did not materially mislead the audience so as to cause harm or offence." On 4 and 5 August 2008, Channel 4 and More 4 broadcast a summary of Ofcom's findings, though it will not face sanctions.
