There have been no hurricanes to make landfall in the USA for over 8 years. Superstorm Sandy was a post-tropical depression when it made landfall with 80 mph winds. We are currently in a remarkable hurricane drought. (We are also in a tornado drought at the moment.) With the most recent 8 of the past 20 years hurricane-free, how does the editor justify the statement that, "over the past 20 years we've seen Atlantic hurricanes cause billions of dollars in damage with increasing frequency."?

One of the little known aspects of global warming theory is that the poles are forecast to warm faster than the equator. Since the temperature difference between the poles and equator is what drives the major air circulation patterns and weather patterns and particularly tropical storms, global warming should actually decrease the frequency and severity of hurricanes. And the official verdict of NOAA after analyzing the historical data is that there has been no increase in hurricanes over the course of the 20th century and to date.

The cost of each major storm event is certainly a function of continued real estate development in vulnerable locations, and shows a rising trend over time, and could be controlled with stricter zoning and building codes. However the frequency of major storms is fortunately not on a rising trajectory.
