Meteorology: Emanuel replies

Kerry Emanuel1

In my original Article1, I showed that there has been a significant upward trend in a measure of tropical-cyclone power dissipation over the past 30 years1. It is important to note that this measure is integrated over the life of the storm, and that the upward increase is evident in all major ocean basins prone to tropical cyclones. However, Pielke 2 finds no discernible trend in hurricane damage in the United States after correction for inflation and demographic trends, and Landsea 3 finds no trend in US landfall-based hurricane power dissipation back to the turn of the last century.
