The Greenhouse Conspiracy is a documentary film broadcast by Channel 4 in the United Kingdom on 12 August 1990, as part of the Equinox series, which criticised the theory of global warming and asserted that scientists critical of global warming theory were denied funding [1]. It is one of the earliest instances of the suggestion of a conspiracy to promote false claims supporting global warming. Although the title of the program implied the existence of a conspiracy, when interviewed on the program Patrick Michaels played down the idea, saying, "It may not quite add up to a conspiracy, but certainly a coalition of interests has promoted the greenhouse theory: scientists have needed funds, the media a story, and governments a worthy cause.
