The problem with this is that the record does NOT show that the
atlantic hurricane pattern has been impacted by any alleged global
warming. In fact, quite the contrary, the period from 1930 to 1960 had
50% more hurricane activity than the next 30 years. The North Atlantic
Occillation is the predominant weather pattern of atlantic hurricanes. 

According to alleged global warming 'experts', the period after 1970
has seen the most warming, yet it was this period that saw the fewest
hurricanes since the 1920's.

In this link, Dr. Chris Landsea of NOAA does a good job of debunking
some of the unsupported claims of Kerry Emanuel who is the main
proponent of linking severe hurricanes with alleged global warming in
his book "Divine Wind".
