A Crimes of the State Investigation
If you track the popular Internet videos, you may have come across a British TV production called The Great Global Warming Swindle (Google Video). I do not wish to defend the propaganda, the personalities, or the several straw man arguments that appear in this lengthy program.
All I want to focus on is the science.
This is a study of some global warming dissenters in the climate field.Al Gore's An Inconvenient Truth is also explored, in particular Gore's central claim, the theory of manmade global warming as a result of increased carbon dioxide in the atmosphere:
"The relationship is very complicated, but there is one relationship that is far more powerful than all the others, and it is this: when there is more carbon dioxide, the temperature gets warmer." --Al Gore, An Inconvenient Truth
This quote is presented in The Great Global Warming Swindle at
around 20 minutes in, and then it is mercilessly shredded by the climate scientists.
According to Al Gore's theory, increased levels of carbon dioxide CAUSE an increase in global temperature. But, interestingly enough, Al Gore does not prove this in his film. Far from it. The very real possibility that increases in temperature cause an increase in carbon dioxide levels (and not vice-versa) is never addressed. Al Gore has short-changed humanity in this most glaring omission: establishing causation.
This is no small question. The entire global economy is being reengineered on the assumption that the first scenario is true. But is it really?
So, which is it?
Does a rise in carbon dioxide cause a rise in the temperature?OR, does a rise in the temperature cause a rise in carbon dioxide?
What About 800 Years of Lag?
The big counter-argument to Gore is made by Professor Ian Clark, Dept. of Earth Sciences at the University of Ottawa. Clark says that the ice core record shows that changes in atomospheric carbon levels come after the temperature has already changed, in one example by as much as 800 years.
This is highly significant, if true, as it completely disproves Al Gore's theory of manmade global warming. This view is seconded by Professor Tim Ball, a Climatologist at the University of Winnipeg:
"CO2 clearly cannot be causing temperature changes. It's a product of temperature. It's following temperature changes." --Professor Ian Clark- Advertisement -
"But the ice core record shows exactly the opposite. So the fundamental assumption, the most fundamental assumption of the whole theory of climate change -- due to humans -- is shown to be wrong." --(emphasis in original) Professor Tim Ball, Dept. of Climatology, University of Winnipeg
Is There a Better Alternative Theory?
The film presents an alternate theory that better matches the data: Changes in sun activity cause changes in global temperature.
