Hurricane in This Century!

My tittle post are adapted from yahoo!green, and you can read in link that I purpose for you, so this short story about that.

With Tropical Storm Guillermo headed toward Hawaii (potentially) in the eastern Pacific and the Atlantic showing the first signs of hurricane-spawning life, the 2009 hurricane season is gearing up.

But what is captivating the public's attention today are two hurricane studies with conclusions that seem to be at odds, continuing the long scientific debate about global warming and other long-term influences on hurricane activity.

The first and most written about study concludes that the Atlantic Ocean is producing more frequent and intense hurricanes than at any time in the past 1,000 years. The study was conducted by the director of the Earth System Science Center at Pennsylvania State University, Michael Mann, a prominent hurricane researcher, and colleagues there and at Woods Hole Oceanographic Institution. Hurricane activity 1,000 years ago may have exceeded the levels seen today, but it's been a long long time since humanity dealt with this level of hurricane activity.

The study, which relied on analysis of ocean sediments, seemed to reinforce the view that there are two primary factors that fuel hurricane activity: The cyclic El Nino-La Nino phases in the southern Pacific Ocean (El Nino, a warming pattern, which we're experiencing now, tamps down hurricane activity, while La Nina boosts it) ... and surface ocean temperature. That final factor is at the center of the debate over global warming's effect on hurricane activity, since global warming may increase the surface temperature of ocean water in parts of the Atlantic.

The second study, however, calls into question the apparent increase in recent (past 100-125 years) hurricane activity. In essence: There appear to be more storms because we're able to detect more short-lived tropical storms than we could before we developed satellite technology and other advanced tracking techniques, according to the National Oceanographic and Atmospheric Administration study published in the Journal of Climate.
