Hurricane boost 'due to warm sea'

02/08/2007

A new analysis of Atlantic hurricanes says their numbers have doubled over the last century. The study says that warmer sea surface temperatures and changes in wind patterns caused by climate change are fuelling much of the increase. Some researchers say hurricanes are cyclical and the increase is just a reflection of a natural pattern. But the authors of this study say it is not just nature - they say the frequency has risen across the century.
