Global Warming Causes
More Fewer Hurricanes
Hurricanes and tropical storms will become less frequent by the end of the century as a result of climate change, US researchers have suggested.
But the scientists added their data also showed that there would be a "modest increase" in the intensity of these extreme weather events.

man-made climate change, which has increased the temperature of the sea surface, is the major factor behind the increase in numbers.
"Over the period we've had natural variability in the frequency of storms, which has contributed less than 50% of the actual increase in our view," said Dr Greg Holland from the United States National Centre for Atmospheric Research in Colorado, who authored the report.
"Approximately 60%, and possibly even 70% of what we are seeing in the last decade can be attributed directly to greenhouse warming," he said.
