One of the scientists who appears in the Channel 4 documentary The Great Global Warming Swindle now claims his views were misrepresented:

Professor Wunsch said: “I am angry because they completely misrepresented me. My views were distorted by the context in which they placed them. I was misled as to what it was going to be about. I was told about six months ago that this was to be a programme about how complicated it is to understand what is going on. If they had told me even the title of the programme, I would have absolutely refused to be on it. I am the one who has been swindled.”

When told what the commission had found, he said: “That is what happened to me.” He said he believes it is “an almost inescapable conclusion” that “if man adds excess CO2 to the atmosphere, the climate will warm”.

He went on: “The movie was terrible propaganda. It is characteristic of propaganda that you take an area where there is legitimate dispute and you claim straight out that people who disagree with you are swindlers. That is what the film does in any area where some things are subject to argument.”

Mr Durkin last night said that Professor Wunsch was “most certainly not duped into appearing into the programme” and that it “had not in any way misrepresented what he said”.
