It seems the more that science supports notions the world is warming because man is pumping CO2 and other greenhouse gases into the atmosphere, the more strident become some of the chief
Global warming deniers n sceptics
- at times, can almost see rabid righties frothing at the mouth.
Lately, been some ballyhoo about a Channel 4 documentary, The Great Global Warming Swindle - in which, argued the sun is behind recent changes, and several scientists wheeled out as sceptics re greenhouse gases. But, seemed that show employed smoke n mirrors. Here are excerpts of transcript of ABC (Australia) interview with American scientist Carl Wunsch, Professor of oceanography at the Massachussetts Institute of Technology, who was interviewed for the documentary - appeared in original version, but whose remarks were eventually edited from the work.
I was told that this was to be a film about the science of global warming, and that it would be an opportunity for me to explain that it is a very complicated problem ... There are a number of issues. There's one point in the film where I was attempting to explain that the ocean contains a very large amount of carbon dioxide that is there naturally. ...
It was put into the film in such a way, in the context that it was put to have me saying that, "Well, carbon dioxide occurs naturally in the ocean and so whatever is going on is all natural," which in some sense turned my point on its head. Or if you like, completely removing the main point, which is while the carbon dioxide in the ocean is primarily there naturally, having it expelled through warming is not necessarily natural. ...
What I thought I was doing, as I said, was making a film about the science of global warming. ...
It's not a science film at all. It's a political statement. ...
The changes that we're seeing today are consistent with a great deal of what we know about the climate system, where there's very little argument about the effects. So, for example, adding carbon dioxide very rapidly that is over periods of decades, which nature doesn't do itself, we can calculate, these are calculations that go back almost 100 years, how much the earth should warm on average. We tend to see that the pattern of warming where more of it takes place at the poles are consistent with an anthropogenic input. Is there is no proof? Well, there is no proof, but science is very rarely about proof, science is about plausibility. Most of the people who work in this subject without guaranteeing anything will say, "It seems very likely that we are seeing human induced warming because it is taking place on time scales that nature does not normally produce".
There is the argument in that film that it's all due to the sun. There is absolutely no evidence, apart from the distortions they made in the graphs in that film in the version that I saw, there's no absolutely no evidence that what we're seeing is due to solar forcing. Will I guarantee what we're seeing is due to anthropogenic causes? No. Do I think it's very likely that it is due to anthropogenic causes, and we should react on that basis? Yes, I do, it's very worrying.

Update, 22 July 2008, from the Independent:
A Channel 4 documentary which claimed that the idea of man-made climate change was a fraud and a conspiracy has been censured by the broadcasting regulator. Ofcom.
The Great Global Warming Swindle, written and directed by Martin Durkin, misrepresented the views of the Government's former chief scientific adviser Sir David King, Ofcom said yesterday in a long-awaited judgement.
The programme was further found to have unfairly treated Sir David, the American oceanographer Professor Carl Wunsch and the UN's Intergovernmental Panel on Climate Change (IPCC) and to have breached the section of the Broadcasting Code relating to impartiality.
The broadcast angered Britain's science community, from the Royal Society down, who accused Mr Durkin of distorting evidence and playing fast and loose with the facts.
Several people who took part said their views had been misrepresented, including Professor Wunsch, of the Massachusetts Institute of Technology, and Dr Eigil Friis-Christensen, the director of the Danish National Space Centre.
The Great Global Warming Swindle was welcomed by a number of right-wing commentators – strange bedfellows for someone with connections to Living Marxism – but sometimes the far right and the far left have much in common.
