Great Global Warming Swindle

From Thomas Sowell's latest column Global Warming Swindle:

Britain's Channel 4 has produced a devastating documentary titled "The Great Global Warming Swindle." It has apparently not been broadcast by any of the networks in the United States. But, fortunately, it is available on the Internet.

The British documentary goes into some of the many factors that have caused the earth to warm and cool for centuries, including changes in activities on the sun, 93 million miles away and wholly beyond the jurisdiction of the Kyoto treaty. According to these climate scientists, human activities have very little effect on the climate, compared to many other factors, from volcanoes to clouds.

These climate scientists likewise debunk the mathematical models that have been used to hype global warming hysteria, even though hard evidence stretching back over centuries contradicts these models.
