Being in the prophecy business is a mug's game



But seeing that the facts are against them, prophecy is all the Warmists have got
(Aug. 31, 2007) — NASA scientists have developed a new climate model that indicates that the most violent severe storms and tornadoes may become more common as Earth’s climate warms.

Previous climate model studies have shown that heavy rainstorms will be more common in a warmer climate, but few global models have attempted to simulate the strength of updrafts in these storms. The model developed at NASA’s Goddard Institute for Space Studies by researchers Tony Del Genio, Mao-Sung Yao, and Jeff Jonas is the first to successfully simulate the observed difference in strength between land and ocean storms and is the first to estimate how the strength will change in a warming climate, including “severe thunderstorms” that also occur with significant wind shear and produce damaging winds at the ground.

This information can be derived from the temperatures and humidities predicted by a climate computer model, according to the new study published on August 17 in the American Geophysical Union’s Geophysical Research Letters. It predicts that in a warmer climate, stronger and more severe storms can be expected, but with fewer storms overall.


Their model makes no sense theoretically or empirically. Severe tornadoes declined as the world warmed from 1975-2000, just as theory predicts they should. Severe tornadoes increased from 1950-1975, as the world cooled. 1975 was the peak of the global cooling panic
