The guys on the Weather Channel say this is NOT caused by global warming.
Warming would cause another El Nino and that tends to suppress hurricanes.

The reality is there are two issues with global warming anyway.

1. Is it really getting warmer?
2. Is that a natural process or something man made?

Since the history of the planet is marked with warming and cooling cycles, we
should really look long and hard at #2.
Throwing another virgin in the volcano never kept it from erupting but it
seemed to make the witch doctor and his followers feel like they were doing
something.
