Channel 4 (UK) takes on Global Warming

Regular readers know the while I feel there is definitive proof of Global Warming, and that I accept that such warming can lead to climate change, I am less convinced of the amount of influence man's activities have on this phenomena. That's why I find it interesting that Channel 4 in the UK, the same people who put out the Undercover Mosque documentary, are doing a special looking at the contrarian view of Global Warming.

From the website:

The film brings together the arguments of leading scientists who disagree with the prevailing consensus that a 'greenhouse effect' of carbon dioxide released by human activity is the cause of rising global temperatures.

Instead the documentary highlights recent research that the effect of the sun's radiation on the atmosphere may be a better explanation for the regular swings of climate from ice ages to warm interglacial periods and back again.

The film argues that the earth's climate is always changing, and that rapid warmings and coolings took place long before the burning of fossil fuels. It argues that the present single-minded focus on reducing carbon emissions not only may have little impact on climate change, it may also have the unintended consequence of stifling development in the third world, prolonging endemic poverty and disease.

The film features an impressive roll-call of experts, including nine professors – experts in climatology, oceanography, meteorology, environmental science, biogeography and paleoclimatology – from such reputable institutions as MIT, NASA, the International Arctic Research Centre, the Institut Pasteur, the Danish National Space Center and the Universities of London, Ottawa, Jerusalem, Winnipeg, Alabama and Virginia.

The film hears from scientists who dispute the link between carbon dioxide levels and global temperatures.

'The ice core record goes to the very heart of the problem we have,' says Tim Ball, Climatologist and Prof Emeritus of Geography at the University of Winnipeg in the documentary. 'They said if CO2 increases in the atmosphere, as a greenhouse gas, then the temperature will go up'.

In fact, the experts in the film argue that increased CO2 levels are actually a result of temperature rises, not their cause, and that this alternate view is rarely heard. 'So the fundamental assumption, the most fundamental assumption of the whole theory of climate change due to humans, is shown to be wrong.'

'I've often heard it said that there is a consensus of thousands of scientists on the global warming issue, that humans are causing a catastrophic change to the climate system,' says John Christy, Professor and Director of the Earth System Science Center, NSSTC University of Alabama. 'Well I am one scientist, and there are many, that simply think that is not true.'
