WASHINGTON, Aug. 12 /U.S. Newswire/ -- Contrary to popular myth the Earth is not warming significantly, according to new research published last month in Geophysical Research Letters by scientists with the universities of Rochester and Virginia.

The reports note two important findings that run counter to the view that human activity is causing catastrophic global warming.

"It's been known for some time that satellites and surface thermometers give different temperature trends," said one of the reports' co-authors Prof. S. Fred Singer, president of the Science & Environmental Policy Project (SEPP). "We now have independent confirmation that the satellite results are correct and that the climate is not warming." Prof. Singer, an adjunct scholar with the National Center for Policy Analysis (NCPA) is also a former director of the U.S. Weather Satellite Service.

Proponents of global warming theory have long pointed to thermometer measurements at the Earth's surface as proof that the Earth is warming. Other scientists have pointed to balloon and satellite readings of temperatures in the Earth's lower atmosphere that show no significant warming. The scientists from the universities of Rochester and Virginia employed a new, independent way of determining the temperature, using historic meteorological climate data to construct temperature values for each grid cell of the Earth at an equivalent height of two meters. This analysis agreed with the satellite and balloon measurements, establishing that the disparity is close to the surface and mainly in the tropics.

In another report, the Rochester/Virginia scientists found that the computer climate models used to assert that the introduction of greenhouse gases, like carbon dioxide (CO2), into the atmosphere is causing the Earth to warm, and that the effect increases with altitude becoming twice as strong at about three miles up, are in stark contrast to the actual data of the past quarter-century. Comparing the results from the three commonly cited climate models with four independent observational data sets, the scientists found that the models all showed temperatures increasing with altitude, while the actual observations showed the opposite occurred.

"If the global climate is not warming, why all the fuss?" asked Singer. "The whole issue of controlling CO2 emissions is moot."
