SlipBall, you give no source for your posting. Where is it from?

In any case, this quotes Kevin Trenberth, head of the Climate Analysis Section at the USA National Center for Atmospheric Research. You might like to see what he had to say about the recent upsurge in extreme tornado activity in the US:

Six severe tornadoes in 11 years could be a natural anomaly, but Kevin Trenberth, senior scientist at the U.S. National Center for Atmospheric Research’s Climate Analysis Section in Boulder, Colo., has a different theory.

“There is climate change going on,’’ he said. “The oceans are now 1 degree Fahrenheit warmer than they were, and that includes the Gulf of Mexico. The warm and moist air coming out of the Gulf plays a key role.’’
