In terms of frequency, studies have consistently shown “no discernible trend in the global number of tropical cyclones.” In addition, authors of a 2013 study found no human-caused signal in annual global tropical cyclone or hurricane frequencies.

Are hurricanes getting stronger?
The authors of that same 2013 study found a substantial regional and global increase in the proportion of the strongest hurricanes – category 4 and 5 storms. The authors attribute that increase to global heating of the climate: “We conclude that since 1975 there has been a substantial and observable regional and global increase in the proportion of Cat 4-5 hurricanes of 25-30 percent per °C of anthropogenic (human-caused) global warming.”

Interestingly, the increase in those most powerful of storms is balanced by a similar decrease in category 1 and category 2 hurricanes. The authors put forth this intriguing theory: “We suggest that this [balance] arises from the capped nature of tropical cyclones to a maximum value defined by the potential intensity, which increases only slightly with global warming.”
