Small increases intemperature found to add power to storms in the Atlantic.
　　Hurricanes that form in the Atlantic Ocean areexpected to gain considerable strength asthe global temperature continues torise, a new study has found.
　　Using modeling data focused on the conditionsin which hurricanes form, a group ofinternational researchers based at BeijingNormal University found that for every 1.8°F ( 1℃ )rise of the Earth's temperature, the number of hurricanes in theAtlantic that are as strong orstronger than Hurricane Katrina will increasetwofold to sevenfold.
　　Hurricane strength is directly related to theheat of the water where the storm forms. Morewater vapor in the air fromevaporating ocean water adds fuel to hurricanes that build strengthand headtoward land.
　　Hurricane Katrina is widely considered themeasure for a destructive storm, holding themaximum Category 5 designation fora full 24 hours in late August 2005. It lost strength as itpassed over theFlorida peninsula, but gained destructive power fight before colliding withNewOrleans, killing more than 200 people and causing $ 80 billion in damage.
　　The study points to a gradual increase ofKatrina-like events. The warming experiencedover the 20th century doubled thenumber of such debilitating(將人類摧垮的)storms. Buttheongoing warming of the planet into the 21st century could increase thefrequency of theworst kinds of storms by 700 percent, threatening coastlinesalong the Atlantic Ocean withmuitiple Category 5 storms every year.
　　"Our results support the idea that changesin regional sea surface temperatures is theprimary cause of hurricanevariability," said Aslak Girnstead, a researcher with the Center forIce andClimate at the University of Copenhagen. The large impact of smallsea-surfacetemperature increases was more than Girustead and his colleagues hadanticipated. Theentire study was published in the Proceedings of the NationalAcademy of Sciences.
　　Global temperatures have steadily increased,making the past decade the warmest onrecord. Earlier this year, climateresearchers reported that the Earth's temperatures have risenfaster in the lastcentury than at any point since the last ice age, 11,300 years ago. Theprimarycause, a couseusus of scientists has said, is the rising emissions ofgreenhousegases like carbon dioxide and methane.
　　Past hurricanes have supported the study'sfinding that global temperature rise is linkedto more destructive storms. Accordingto the National Center for Atmospheric Research, whilethe frequency of stormsdoesn't appear to have increased, the percentage of strong ones hasrisensharply over the past few decades. The trend may be similar further back intime, butcomprehensive hurricane data doesn't exist.
