Global Warming Will Bring Violent Storms And Tornadoes, NASA Predicts
ScienceDaily (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

GISS has been renamed to GIGO as that best represents their work product!
1884 was known as the Enigma Tornado Outbreak.
Feb 19-20 there were more than 60 tornadoes on the ground, in one 15 hour period.
Estimated that up to 1200 people were killed. That’s at a lot lower population density than today.
The model assumed an earth 5 degrees warmer. We might be there in a century and then let’s see your graph.
The model did not say storms would suddenly get stronger when temps got 5 degrees warmer. Whay was said was :-
The prediction of stronger continental storms and more lightning in a warmer climate is a natural consequence of the tendency of land surfaces to warm more than oceans and for the freezing level to rise with warming to an altitude where lightning-producing updrafts are stronger. These features of global warming are common to all models, but this is the first climate model to explore the ramifications of the warming for thunderstorms.
In other words stronger storms would be a natural consequence of any warming however small.
Don’t expect consistency from Daniel. I think he’s having trouble thinking clearly because of the tailspin the political left is in over Donald Trump.
Apparently, tornados are hardly seen in the tropics.
Yes, severe tornadoes are decreasing. But it’s from global warming. Yes, global warming did predict more severe weather. But that prediction is wrong because of global warming. Global warming causes everything—even wrong predictions for global warming.
