Tornado Alley (PROG)

The Sunday Times had reported that the IPCC included the reference to the then unpublished study despite doubts raised by at least two scientific reviewers at the time.

Professor Jean-Pascal van Ypersele, a climatologist at the Universite Catholique de Louvain in Belgium and the vice-chairman of the IPCC, was quoted by the newspaper as saying that the panel was reassessing the evidence.

It was the second time in recent weeks that doubt was cast on the scientific validity some of the evidence used in the UN panel's reports.

The IPCC last week admitted errors in a forecast about melting Himalayan glaciers that was included in a landmark 2007 report.


Professor Richard Lindzen of MIT, perhaps the most distinguished climatologist in the world, the message of this gathering was that the scare over global warming has been deliberately stoked up for political reasons and has long since parted company with proper scientific evidence.

Nothing has more acutely demonstrated this than the reliance of the IPCC on computer models to predict what is going to happen to global temperatures over the next 100 years. On these predictions, that temperatures are likely to rise by up to 5.3C, all their other predictions and recommendations depend, yet 10 years into the 21st century it is already painfully clear that the computer forecasts are going hopelessly astray. Far from rising with CO2, as the models are programmed to predict they should, the satellite-measured temperature curve has flattened out and then dropped. If the present trend were to continue, the world in 2100 would not in fact be hotter but 1.1C cooler than the 1979-1998 average.

Yet it is on this fundamental inability of the computer models to predict what has already happened that all else hangs. For two days in New York we heard distinguished experts, such as Professor Syun-Ichi Akasofu, former director of the International Arctic Research Center, Dr Willie Soon of the Harvard-Smithsonian Center for Astrophysics and Professor Paul Reiter of the Pasteur Institute, authoritatively (and often wittily) tear apart one piece of the scare orthodoxy after another.
