Has there been a “decrease in hurricane activity,” though? Or just a decrease in the number of large hurricanes that have hit the U.S.? The article notes that there have been plenty of major hurricanes in the past 10 years? But that they have all missed the U.S. - I think that is the “dumb luck”
Actually it’s both fewer and smaller hurricanes and fewer making North American landfall.
Call it luck, call it fate, it’s welcome for whatever the reason.
