My  Short  Summary:
 This study examines U.S. hurricane trends in the Atlantic Basin over the period 1851-2017, looking at landfall counts (frequency) and accumulated cyclone energy (intensity).

Hurricane landfall counts in the USA (Category 1-5), and major hurricanes  (Category 3 or greater) both had a small declining trend across the 167-year period.

For different starting points, 1851, 1900, and 1980, the same results.
But short periods, less than 30 years, "are likely to give strong positive or negative trends even when the entire data series has no significant trend."

For accumulated cyclone energy (ACE) data "as with the count data, the 119 year [ACE] data have essentially a zero trend."
