Read here. From the "experts" that predicted more hurricanes back in 2005, a group of hurricane modelers create a new model that concludes there will be less hurricanes (about 33% less) in the Atlantic basin, but the number of intense storms will increase by 81% due to CO2-caused global warming. One would hope that these continuous attempts to predict future hurricane activity and intensity would improve, but this new hurricane simulator seems to have some very fundamental problems:
"But a closer look at the results shows that this model-based result is produced by a hurricane model which under-simulates the frequency of strong storms in today’s climate. And that, despite the projected increase in intense hurricanes, the frequency of those storms projected by the model to occur by the end of the 21st century is considerably less than the frequency of intense hurricanes actually observed in the current climate. If the model doesn’t work for the present, why should we trust it for the future?....The bottom line is that if a model doesn’t perform very well in a particular area of interest—in this case in simulating the observed frequency of intense hurricanes—then that model shouldn’t be considered a reliable estimator of how the characteristics of that area of interest will change in the future."
