With global warming, hurricanes are most likely going to be appearing more and more; and the hurricane season will be longer.  The fact is, as the earth’s climate changes, the warm currents in the ocean will eventually have currents that will cross each other, which will diminish the occurrence of a hurricane; but this will not happen for years.  In the meantime, as the ocean slowly becomes warmer, we can all expect to see more hurricanes per year, and possibly more category 5 hurricanes than the earth has ever witnessed.
