given the increasing energy available for storm development in the oceans, its not frequency that changes but the intensity.

The authors assessed more than 90 peer-reviewed scientific articles, with a focus on articles describing observations of, or projected future changes to, the frequency and intensity of tropical cyclones (TCs) globally or in key regions, as well as changes in tropical cyclone-related rainfall and storm surge.

Warming of the surface ocean from anthropogenic (human-induced) climate change is likely fueling more powerful TCs. The destructive power of individual TCs through flooding is amplified by rising sea level, which very likely has a substantial contribution at the global scale from anthropogenic climate change. In addition, TC precipitation rates are projected to increase due to enhanced atmospheric moisture associated with anthropogenic global warming.

admittedly though there is some disagreement between an regarding an increased incidence/frequency of Tropical Storms and Cyclones. but from the evidence so far it remains most noticeable that the intensity (energy) of storms has significantly increased.more severe flooding resulting in more deaths and destruction.
