OK, so there hasn’t been any great increase in potential intensity of tropical cyclones over the long run, despite what the global warming advocates would lead you to believe. Well, you could suggest that like everything else, the disaster will reveal itself a decade or so from now. Unfortunately for such optimists (or are they pessimists?), Vecchi and Soden calculated PI for the next 150 years, and as seen below, SSTs are expected to rise, but in the North Indian Ocean and the tropical Atlantic Ocean, there should be no rise whatsoever in potential intensity of hurricanes.

Let’s all wait and see if the global warming crowd (or the media) embraces these results – of course they won’t and of course they will continue to scream that hurricanes are becoming more intense and will become even more intense in the decades to come. The results published in Nature by Vecchi and Soden will be nothing more than inconvenient trash to be swept under the rug of truth!
