The great global warming swindle

At last a documentary that treats its audience as adults - BBC, please note. Channel 4 has supported the programme with a website broken into bite sized chunks.

The Financial Times' preview was almost apologetic for highlighting the programme, such is the sway of the green religion. And Channel 4's introduction stressed how controversial the programme was.

Mr Miliband regards the science as settled, however. So he should find the science in the programme easy to rebut. Mr Blair claimed the Stern Report (remember that?) was the most important document he had ever received. For Mr Cameron greenness seems to be an article of faith (but then I'm not sure he does analysis).

The programme did mention the religious role of greenery, but didn't have time to venture into the politics. It will be interesting to read the objections to the programme's thesis that global warming is a frequent event in the earth's history and is not caused by man.

Meanwhile, Viscount Monckton's latest piece lists "some of the dozens of fundamental scientific errors in Gore’s film", including -

· Gore, aiming to undermine the significance of previous warm periods such as that of the Middle Ages, promoted the 1,000-year “hockey stick” temperature chart

· Gore showed heart-rending pictures of the New Orleans floods and insisted on a link between increased hurricane frequency and global warming that has no basis in scientific fact

· Gore asserted that today’s Arctic is experiencing unprecedented warmth while ignoring that Arctic temperatures in the 1930s and 1940s were as warm or warmer

· Gore did not explain that Arctic temperature changes are more closely correlated with changes in solar activity than with changes in atmospheric CO2 concentrations

· Gore did not explain that the Sun has been hotter, for longer, in the past 50 years than in any similar period in at least the past 11,400 years

· Gore said the Antarctic was warming and losing ice but failed to note, that is only true of a small region and the vast bulk of the continent has been cooling and gaining ice

· Gore hyped unfounded fears that Greenland’s ice is in danger of disappearing. In fact its thickness has been growing by 2 inches per year for a decade

· Gore falsely claimed that global warming is melting Mt. Kilimanjaro’s icecap, actually caused by atmospheric dessication from local deforestation, and pre-20th-century climate shifts

· Gore said the ocean absorbs heat from the Sun, when in fact the ocean takes nearly all of its heat from the atmosphere, without which the ocean would freeze over

· Gore implied that changes in temperature followed changes in CO2 concentration in the past 500,000 years, but in fact temperature changes preceded changes in CO2 concentration.
Were these and other serious errors accidental? It is unlikely. Every single one of the errors magnifies, overstates, or exaggerates the supposed problem. Not one of the errors understates it.
