Study: Global Warming May Suffocate Hurricanes
Thursday , April 19, 2007

WASHINGTON
The debate over whether global warming affects hurricanes may be running into some unexpected turbulence.

Many researchers believe warming is causing the storms to get stronger, while others aren’t so sure.

Now, a new study raises the possibility that global warming might even make it harder for hurricanes to form.

The findings, by Gabriel A. Vecchi of the National Oceanic and Atmospheric Administration and Brian J. Soden of the University of Miami, are reported in Wednesday’s issue of Geophysical Research Letters.

Vecchi and Soden used 18 complex computer climate models to anticipate the effects of warming in the years 2001-2020 and 2018-2100.

Included in the results were an increase in vertical wind shear over the tropical Atlantic and eastern Pacific oceans.

Vertical wind shear is a difference in wind speed or direction at different altitudes. When a hurricane encounters vertical wind shear the hurricane can weaken when the heat of rising air dissipates over a larger area.

On the other hand, warm water provides the energy that drives hurricanes, so warmer conditions should make the storms stronger.

“We don’t know whether the change in shear will cancel out the increased potential from warming oceans, but the shear increase would tend to make the Atlantic and East Pacific less favorable to hurricanes,” said Vecchi, of NOAA’s Geophysical Fluid Dynamics Laboratory in Princeton, N.J.

“Which one of the two

I believe last I heard that over 80% of the scientific community do agree that it is happening, minus the few Oil funded scientist that are the Nay sayers.

What you are referring to is climate change, which is a result of global warming. The climate change theory is that as the arctic shelf, glaciers and other icecaps melt, the intrusion of fresh cold water into our existing jet streams will produce changes to the jetstreams which will affect the weather. Now what those effects are I dont think anyone can predict.

it may reduce hurricanes for gulf coast regions and create hurricanes where they once never were. Or they could increase hurricanes in gulf coast regions and do whatever else.

The fact is global warming is happening, and climate change is a result, but what changes will happen, I think its too early to tell.

PS. always check your sources, and the scientist and see who is funded by who, as this will tell you alot about their views.

I don’t think that there is any question about it. Global warming is happening, and we must acknowledge it.

Ask anyone from any part of the world , has the weather changed dramatically since you were a kid ? has it changed much faster in the last 10 years ? is it getting worse , the answer will always be yes
