Remember all those reports after Hurricane Katrina about how global warming is causing more frequent, more powerful hurricanes? Well, never mind about that. At least that's what a new study in Geophysical Research Letters says, claiming that rising temperatures are creating wind shear that interferes with hurricane formation. (As you may recall, wind shear was blamed for the rather shy 2006 and 2007 hurricane season the U.S. experienced.)

Lead author Chunzai Wang said the study findings were based not on computer models but on observations. The study found that average wind shear increases about 10 miles per hour for every 1 degree C. rise in temperature.

The prediction is that increased warming will result in less hurricane landfalls in the U.S., but there is, of course, controversy here.
