As I summarize in the book: «global warming, which ought to intensify the average hurricane, could also change the regions of storm formation or the numbers of storms that form in the first place.

The perceptible (and perhaps measurable) impact of global warming on hurricanes in today's climate is arguably a pittance (or noise) compared to the reorganization and modulation of hurricane formation locations and preferred tracks / intensification corridors dominated by ENSO (and other natural climate factors).
