Satellites Quantify Rainfall/Temp – 5 Times More than IPCC predicions.

PASADENA, Calif. (AP) — The frequency of extremely high clouds in Earth’s tropics — the type associated with severe storms and rainfall — is increasing as a result of global warming, according to a study by scientists at NASA’s Jet Propulsion Laboratory, Pasadena, Calif.
In a presentation today to the fall meeting of the American Geophysical Union in San Francisco, JPL Senior Research Scientist Hartmut Aumann outlined the results of a study based on five years of data from the Atmospheric Infrared Sounder (AIRS) instrument on NASA’s Aqua spacecraft.
For every 1.8-degree (F) increase in average ocean surface temperature, the team observed a 45-percent increase in the frequency of the very high clouds. At the present rate of global warming of 0.23 degrees per decade, the team inferred the frequency of these storms can be expected to increase by six percent per decade.
Everything was going fine until this last paragraph. Point two three, you sure big guy. Who says point two three, even GISS data only says 0.18/decade. The last decade showed little or no warming whatsoever. A flat line.
“Clouds and rain have been the weakest link in climate prediction,” said Aumann. “The interaction between the daytime warming of the sea surface under clear-sky conditions and increases in the formation of low clouds, high clouds and, ultimately, rain is very complicated.
There it is, what every skeptic/denialist already knew. Clouds and rain are the weakest link. Well they have some data now, watch out.
Aumann said the results of his study, published recently in Geophysical Research Letters, are consistent with another NASA-funded study by Frank Wentz and colleagues in 2005. That study found an increase in the global rain rate of 1.5% per decade over 18 years, a value that is about five times higher than the value estimated by climate models that were used in the 2007 report of the Intergovernmental Panel on Climate Change.
Five times more increase than AR4! Wow, that will probably make the cut for the next IPCC bible.
