The Great Global Warming Swindle, a controversial Channel 4 film, broke Ofcom rules, the media regulator says.
In a long-awaited judgement, Ofcom says Channel 4 did not fulfil obligations to be impartial and to reflect a range of views on controversial issues.
The film also treated interviewees unfairly, but did not mislead audiences "so as to cause harm or offence".
Plaintiffs say the Ofcom judgement is "inconsistent" and "lets Channel 4 off the hook on a technicality."
The film's key contentions were that the increase in atmospheric temperatures observed since the 1970s was not primarily caused by emissions of greenhouse gases from burning fossil fuels, and that the modern focus on climate change is based in politics rather than science.
