Karl : Klueless On Hurricanes | Real Science

Since the year 1993, the US has had one category 4 hurricane (Charley) and zero category 5 strikes.

By contrast, between 1954 and 1969, the US had four category 4 hurricanes (Hazel, Audrey, Donna, Carla) and one category 5 hurricane (Camille)

According to Hansen, this flurry of major hurricanes occurred during a period of strong cooling in the US. Category 5 Camille occurred during one of the coldest years of the last century, in 1969.
