Top graph is count of landfall Atlantic hurricanes. Also:
Another metric for measuring hurricane and tropical storm intensity is the ACE (Accumulated Cyclone Energy) index, which is defined as the sum of the squares of the maximum sustained surface wind speed (knots) measured every six hours for all named storms while they are at least tropical storm strength. The graphic below plots the North Atlantic ACE index since 1950. The trend line is dead flat.Hat tip to SmallDeadAnimals.
