'Global Warming Swindle' sparks debate
The film featured the views of scientists and green campaigners who rejected commonly held views outlined in the media and in Al Gore's film An Inconvenient Truth that carbon dioxide has caused global warming.
The compelling programme has so far provoked 144 complaints to Ofcom. Channel 4 said though it had received 758 calls and emails from viewers about the film, those in favour of the broadcast outnumbered complaints by six to one.
The show, which aired at 9pm last Thursday, attracted a healthy 2.5 million viewers and an 11.5% audience share.
Martin Durkin, who made the film, denied reports that featured scientist Carl Wunsch was duped into appearing in the documentary and criticised the BBC and Channel 4 News for "brainwashing the public" by taking a strong editorial line supporting the global warming theory.
