Zbigniew Jaworowski's demolition of climate science

If you haven't seen it yet then Zbigniew Jaworowski's demolition of the state of climate science is well worth catching up with. Jaworowski is an old school scientist, one of the type that still believe in those pesky things that climate scientists and their Brown Shirt brigade have so much trouble with - facts.

He refers to the Four Basic IPCC Lies:

1. Carbon dioxide, the most important anthropogenic greenhouse gas, increased markedly as a result of human activities, and its atmospheric concentrations of 379ppmv (parts per million by volume) in 2005 by far exceeded the natural range of 180 to 300ppmv over the last 650,000 years.
2. Since 1750, human activities have warmed the climate.
3. The warmth of the last half-century is unusual, is the highest in at least the past 1,300 years, and is "very likely" caused by increases in anthropogenic greenhouse gas concentrations.
4. Predictions are made that anthropogenic warming will continue for centuries, and between 2090 and 2099 the global average surface temperature will increase 1.1C to 6.4C. Various scare stories of global catastrophes are prophesied to occur if man-made emissions are not curbed by drastic political decisions. The obvious beneficial effects of warming for man and all of the biosphere are downplayed.

When people say that the "science is settled" why is it that there seems to be such a growing contrarian body of science? It's a strong article and well worth reading the whole thing.
