It can be seen that the recent period’s CO2-enriched atmosphere witnessed a 56 percent drop in the number of hurricanes hitting the U.S. The force of the hurricanes has decreased as well, with by far the worst of the period being Hurricane Hazel in 1954, which featured 150 mph winds and sea surges of up to 18 ft along major sections of the Carolina coast. Further information concerning historic hurricanes can be found in an excellent article by Anthony Watts.
