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.
