Global Warming Models Are Wrong Again
The Wall Street Journal

(By WILLIAM HAPPER, professor of physics at Princeton) What is happening to global temperatures in reality? The answer is: almost nothing for more than 10 years (monthly values of the global temperature anomaly of the lower atmosphere, compiled at the University of Alabama from NASA satellite data). The latest monthly global temperature anomaly for the lower atmosphere was minus 0.12 degrees Celsius, slightly less than the average since the satellite record of temperatures began in 1979.

The lack of any statistically significant warming for over a decade has made it more difficult for the United Nations Intergovernmental Panel on Climate Change (IPCC) and its supporters to demonize the atmospheric gas CO2 which is released when fossil fuels are burned. The direct warming due to doubling CO2 levels in the atmosphere can be calculated to cause a warming of about one degree Celsius. The IPCC computer models predict a much larger warming, three degrees Celsius or even more. Many lines of observational evidence suggest that this « positive feedback » also has been greatly exaggerated.

Frustrated by the lack of computer-predicted warming over the past decade, some IPCC supporters have been claiming that « extreme weather » has become more common because of more CO2. But there is no hard evidence this is true.
