Any level of fanaticism can be wrought from statistics. The devil is in the raw data ie: the percentage of cat 4-5 weather events doubled in the last decade. The actual number rose from 2% to 4% - an insignificant increase.
But going from 2% to 4% is still a doubling.
IIRC, The referenced paper of which Curry’s work was a part mainly reflected a combination of now being able to see cat4s and 5s which did not make landfall, and the increased value of real-estate.
