NEW YORK - July 18, 2008 - A
mathematical proof that there is no “climate crisis” has been published in
debate on global warming in Physics and Society, a scientific
publication of the 46,000-strong American Physical Society.
Christopher Monckton, who once advised Margaret Thatcher, demonstrates via 30 equations that computer models used by the United Nation’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.
The article, entitled 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.”
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.
