My take is Global Warming is nearly completely theoretical, with enphasis on the Retorical.
Political Science rather than science. It belongs in the same unscientific catagory as the philosophy, not science, of "the many worlds theory" or any variations of string theory.
From the Manchester Guardian, hardly a liberal rag:
The denial industry, which has no interest in establishing the truth about global warming, insists that these emails, which concern three or four scientists and just one or two lines of evidence, destroy the entire canon of climate science.
Even if you were to exclude every line of evidence that could possibly be disputed – the proxy records, the computer models, the complex science of clouds and ocean currents – the evidence for man-made global warming would still be unequivocal. You can see it in the measured temperature record, which goes back to 1850; in the shrinkage of glaciers and the thinning of sea ice; in the responses of wild animals and plants and the rapidly changing crop zones.
No other explanation for these shifts makes sense. Solar cycles have been out of synch with the temperature record for 40 years. The Milankovic cycle, which describes variations in the Earth's orbit, doesn't explain it either. But the warming trend is closely correlated with the accumulation of heat-trapping gases in the atmosphere. The impact of these gases can be demonstrated in the laboratory. To assert that they do not have the same effect in the atmosphere, a novel and radical theory would be required. No such theory exists. The science is not fixed – no science ever is – but it is as firm as science can be. The evidence for man-made global warming remains as strong as the evidence linking smoking to lung cancer or HIV to Aids.
