Severe Hurricanes Increasing, Study Finds

A new study concludes that rising sea temperatures have been accompanied by a significant global increase in the most destructive hurricanes, adding fuel to an international debate over whether global warming contributed to the devastation wrought by Hurricane Katrina.
The study, published today in the journal Science, is the second in six weeks to draw this conclusion, but other climatologists dispute the findings and argue that a recent spate of severe storms reflects nothing more than normal weather variability.
