This time though its John Kerry blaming the tornados on Global warming. The Business and Media Institute does a little digging and comes up with this:
“Roger Edwards, a meteorologist at the Storm Prediction Center of the National Weather Center in Norman, Okla., has doubts about any global warming and tornado relationship.
“As of this writing, no scientific studies solidly relate climatic global temperature trends to tornadoes,” Edwards wrote on the Earth & Sky Web site in April 2007. “I don’t expect any such results in the near future either, because tornadoes are too small, short–lived, hard to measure and count, and too dependent on day to day, even minute to minute “
Meanwhile we have record snow in the midwest and record cold earlier in the week. What could be the culprit? How about La Nina.
