You need to have lots of warm sea water (>27 degress C) to get a hurricane.
Therefore hurricanes only appear in places north or south of the equator
which do have direct sea access to the equator. A hurricane tend to blow
away :-) when it hits higher ground.
So... global warning would mean more warm sea water, and thus extended
hurricane belts.
