Number of hurricanes doubled due to global warming The number of
Atlantic hurricanes in an average season has doubled in the last
century due in part to warmer seas and changing wind patterns
caused by global warming, according to a study released on
Sunday. Hurricane researchers have debated for years whether
climate change caused by greenhouse gases from cars, factories
and other human activity is resulting in more, and more intense,
tropical storms and hurricanes. The new study, published online
in Philosophical Transactions of the Royal Society of London,
said the increased numbers of tropical storms and hurricanes in
the last 100 years is closely related to a 1.3-degree Fahrenheit
rise in sea surface temperatures. The influential U.N.
Intergovernmental Panel on Climate Change, in a report this year
warning that humans contribute to global warming, said it was
“more likely than not” that people also contribute to a trend of
increasingly intense hurricanes. In the new study, conducted by
