There was a lot of hurricanes when I was a kid. The a dearth of them for about 2 decades. Then a bunch.
In 1900 Texas there was a storm that killed 12000 in Galveston Texas. Storms like Katrina didn't come close. Yet we blame Katrina and Sandy on global warming when a century ago storms were much worse and even worse in the 17 and 18th century where whole fleets of ships were sunk.
Indeed. However, for a storm with intensity at 1:100 year probability to recur within 5 years is a bit hard. Cumbria and the Lake District had one almost as severe in total rainfall, and equally severe in destructive effect, in 2010.
