>Martin Durkin defended his documentary the Great Global Warming Swindle after a debate which followed its airing in Australia failed to allow him to adequately respond.

He has modified his documentary several times. I think this is a good thing. There were several criticisms and presumably he sort to address them. He also removed comments by the Professor of Physical Oceanography at MIT, who said he had been misrepresented. Using someone’s beliefs to show consequences in a documentary that they do not support is not misrepresentation nor quoting out of context, it is a situation of using a hostile witness. Of course hostile witnesses hate their ideas being used by the opposition, otherwise they would not be hostile. Using the data of another but putting forward one’s own theory as to the explanation is completely legitimate. Nevertheless Durkin has complied with the request which is honourable given that he didn’t misquote originally.

In a previous post I discussed the sun temperature graph. Merchant made some accusations about data manipulation that turned out not to be true. He initially acknowledged this on his home page but currently just shows graphs of the data extended beyond 1980.

It appears that the new documentary has an updated graph. This one shows data for the 20 years beyond 1980 and shows that the prediction continues to hold.

I am not certain how these graphs line up. Given that Merchant was unaware of how the graph was constructed the first time, I will give Durkin’s men the benefit of the doubt for the time being.

There is obviously far more research to be done on the subject of the sun influencing the Earth’s weather. And we must be careful against making too much of one graph. But the correlation is strong enough to encourage further investigation into solar activity and the weather.

Merchant may have reasons to think that CO2 is a bigger influence on the climate, but the solar data are enough to suggest the sun may have some influence; on the variation that is, everyone acknowledges it warms the planet.

It may turn out that the Earth’s weather is influenced by that enormous object of burning gas in the sky—who would have thought?
