Convincing research shows that the number and strength of hurricanes is inversely proportional to the amount of high atmosphere dust over Africa. Changes in ocean temp had much less effect.
The storms are born off the east coast of Africa and when dust levels are "normal", the dust blowing off the continent squelches them, seeds rainfall and dampens their energy or something (they didn't suggest the mechanism). During recent high activity, dust was dramatically lower and more storms survived and grew to hurricane strength. They didn't speculate what was modulating the millions of tons of dust normally suspended over the Sahara. 

Maybe global cooling is reducing dust storms which is increasing hurricanes.

This certainly sounds more plausable than anything else recently published.


I think you will find that ocean temperatures are the most important factor.
During the recent peak years the Atlantic was warmer, then it suddenly cooled and activity dropped dramatically in the past two years.
The historic 30-40 year peaks hurricane activity are well documented. The period between the 60's and the late '90s was remarkably low in activity.
