Hurricane study whips up a storm

Rising ocean temperatures linked to global warming could decrease the number of hurricanes hitting the United States, say researchers. But their findings have been questioned by some at a recent meteorology conference.
The new study challenges research suggesting that global warming could be contributing to an increase in the frequency and the intensity of Atlantic hurricanes. Hurricanes feed on warm water, leading to conventional wisdom supported by recent research that global warming could be revving up more powerful storms.
Chunzai Wang of the US National Oceanic and Atmospheric Administration and Sang-Ki Lee of the University of Miami, US, examined 150 years of hurricane records and found a small decline in hurricanes making landfall in the United States as oceans warmed.
Wang says the number of those hurricanes actually hitting the United States is a much better indicator than the total number of hurricanes. This is because prior to the mid-1960s, when the advent of satellites and other technology made it easier to spot cyclones, some tropical storms and hurricanes lived and died far out at sea, undetected.
