"Top researchers now agree that the world is likely to get stronger but fewer hurricanes in the future because of global warming, seeming to settle a scientific debate on the subject.

But they say there's not enough evidence yet to tell whether that effect has already begun.

Since just before Hurricane Katrina hit Louisiana and Mississippi in 2005, dueling scientific papers have clashed about whether global warming is worsening hurricanes and will do so in the future. The new study seems to split the difference. A special World Meteorological Organization panel of 10 experts in both hurricanes and climate change — including leading scientists from both sides — came up with a consensus, which is published online Sunday in the journal Nature Geoscience.

"We've really come a long way in the last two years about our knowledge of the hurricane and climate issue," said study co-author Chris Landsea, a National Oceanic and Atmospheric Administration top hurricane researcher. The technical term for these storms are tropical cyclones; in the Atlantic they get called hurricanes, elsewhere typhoons."
