Proved: There is no climate crisis

A major new paper shows CO2’s effect on temperature was overstated 500-2000% by the IPCC.

WASHINGTON (7-15-08) - Mathematical proof that there is no “climate crisis” appears today in a major, peer-reviewed paper in Physics and Society, a learned journal of the 10,000-strong American Physical Society, SPPI reports.

Christopher Monckton, who once advised Margaret Thatcher, demonstrates via 30 equations that computer models used by the UN’s climate panel (IPCC) were pre-programmed with overstated values for the three variables whose product is “climate sensitivity” (temperature increase in response to greenhouse-gas increase), resulting in a 500-2000% overstatement of CO2’s effect on temperature in the IPCC’s latest climate assessment report, published in 2007.

Climate Sensitivity Reconsidered demonstrates that later this century a doubling of the concentration of CO2 compared with pre-industrial levels will increase global mean surface temperature not by the 6 °F predicted by the IPCC but, harmlessly, by little more than 1 °F. Lord Monckton concludes –

“… Perhaps real-world climate sensitivity is very much below the IPCC’s estimates. Perhaps, therefore, there is no ‘climate crisis’ at all. … The correct policy approach to a non-problem is to have the courage to do nothing.”

The full report, Climate Sensitivity Reconsidered is available at the American Physical Society (APS) website newsletter Physics & Society: July 2008.

Lord Monckton’s paper reveals that –

• The IPCC’s 2007 climate summary overstated CO2’s impact on temperature by 500-2000%;
• CO2 enrichment will add little more than 1 °F (0.6 °C) to global mean surface temperature by 2100;
• Not one of the three key variables whose product is climate sensitivity can be measured directly;
• The IPCC’s values for these key variables are taken from only four published papers, not 2,500;
• The IPCC’s values for each of the three variables, and hence for climate sensitivity, are overstated;
• “Global warming” halted ten years ago, and surface temperature has been falling for seven years;
• Not one of the computer models relied upon by the IPCC predicted so long and rapid a cooling;
• The IPCC inserted a table into the scientists’ draft, overstating the effect of ice-melt by 1000%;
• It was proved 50 years ago that predicting climate more than two weeks ahead is impossible;
• Mars, Jupiter, Neptune’s largest moon, and Pluto warmed at the same time as Earth warmed;
• In the past 70 years the Sun was more active than at almost any other time in the past 11,400 years.

Update: from the APS Physics and Society website:

There is a considerable presence within the scientific community of people who do not agree with the IPCC conclusion that anthropogenic CO2 emissions are very probably likely to be primarily responsible for the global warming that has occurred since the Industrial Revolution.

Also this report from DailyTech:

The American Physical Society, an organization representing nearly 50,000 physicists, has reversed its stance on climate change and is now proclaiming that many of its members disbelieve in human-induced global warming. The APS is also sponsoring public debate on the validity of global warming science. The leadership of the society had previously called the evidence for global warming "incontrovertible."

After publication of this story, the APS responded with a statement that its Physics and Society Forum is merely one unit within the APS, and its views do not reflect those of the Society at large.

At least the Physics and Society people at APS are encouraging debate on the science. That's long overdue.
