Yet another global warming record

Hurricanes declining.

Global Hurricane Frequency – 1978 to Present

Global Hurricane Frequency (all & major) — 12-month running sums. The top time series is the number of global tropical cyclones that reached at least hurricane-force (maximum lifetime wind speed exceeds 64-knots). The bottom time series is the number of global tropical cyclones that reached major hurricane strength (96-knots+). Adapted from Maue (2011) GRL.
 
But... but... but...

The experts said they would get more intense!

And if you look at the Ryan Maue graphic that Jack Hays posted,
it looks like that's exactly what's happened. Well really, there
are two time series on that graph, and the lower one is for Major
Hurricanes of 96 kts or more. And it looks like in the early '70s
there were between 10 and 20 major storms per year and for the
last few years it looks like it's around 30 per year. Dr. Maue didn't
provide a trend line but it sure looks like an upward trend to me.

For all sorts of reasons I wish that what that graph says isn't so,
but I gotta be honest, sure looks like globally, hurricanes have
gotten more intense.
