Study Says Global Warming Boosts Hurricanes’ Intensity
Research Finds Major Storms Have Increased in Duration, Strength Since 1970s

Is global warming making hurricanes more ferocious? New research suggests the answer is yes. Scientists call the findings both surprising and ‘‘alarming’’ because they suggest global warming is influencing storms now - rather than in the distant future.

The analysis by climatologist Kerry Emanuel of the Massachusetts Institute of Technology shows for the first time that major storms spinning in both the Atlantic and the Pacific since the 1970s have increased in duration and intensity by about 50 percent.

These trends are closely linked to increases in the average temperatures of the ocean surface and also correspond to increases in global average atmospheric temperatures during the same period.

’‘When I look at these results at face value, they are rather alarming,’’ said research meteorologist Tom Knutson. ‘‘These are very big changes.’‘

Before this study, most researchers believed global warming’s contribution to powerful hurricanes was too slight to accurately measure. Most forecasts don’t have climate change making a real difference in tropical storms until 2050 or later.

Theories and computer simulations indicate that global warming should generate an increase in storm intensity, in part because warmer temperatures would heat up the surface of the oceans. Especially in the Atlantic and Caribbean basins, pools of warming seawater provide energy for storms as they swirl and grow over the open oceans.

Emanuel analyzed records of storm measurements made by aircraft and satellites since the 1950s. He found the amount of energy released in these storms in both the North Atlantic and the North Pacific oceans has increased, especially since the mid-1970s.

In the Atlantic, the sea surface temperatures show a pronounced upward trend. The same is true in the North Pacific, though the data there is more variable, he said.

’‘This is the first time I have been convinced we are seeing a signal in the actual hurricane data,’’ Emanuel said.

’‘The total energy dissipated by hurricanes turns out to be well correlated with tropical sea surface temperatures,’’ he said. '‘The large upswing in the past decade is unprecedented and reflects the effects of global warming.’'

This year marked the first time on record that the Atlantic spawned four named storms by early July, as well as the earliest category 4 storm on record. Hurricanes are ranked on an intensity scale of 1 to 5.

Details of Emanuel’s study appear Sunday in the online version of the journal Nature.

Oh, you know we can’t trust scientists! :)

No, no… it’s not global warming. It’s what Ross Perot predicted would happen if the USA ratified NAFTA. It is the low pressure induced by all of our jobs being sucked down to Mexico, Haiti, etc…

Global Warming… pfftt! :D


Hey gtr4him:
I like that… lol… Good One… :O :laugh:
