The Great Global Warming Swindle

The Great Global Warming Swindle is a controversial documentary film by British television producer Martin Durkin, which argues against the scientific opinion that human activity is the main cause of global warming. The film showcases scientists, economists, politicians, writers, and others who are skeptical of the scientific consensus on anthropogenic global warming. Publicity for the program states that global warming is "a lie" and "the biggest scam of modern times."

The program's accuracy has been disputed on multiple points and several commentators have criticized it for being one-sided, noting that the mainstream position on global warming is supported by the scientific academies of the major industrialized nations and other scientific organizations. The film disputes the positions of these scientific organizations by interviewing scientists and others, including Richard Lindzen and other contributors to reports by the IPCC, who disagree with explanations that attribute global warming to human activities.

Channel 4, which screened the documentary on March 8, 2007, 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."
