Global Warming and Hurricane Rapid Intensification Rates?

My latest "Storm Pundit" column on this subject, which has come to seem fairly pressing in the wakes of Hurricanes Felix and Humberto, is now up. Upshot: I want to know more about the mechanism by which climate change would presumably affect storm intensification rates. Still, it stands to reason that some type of change ought to occur--and given how dangerous rapidly intensifying hurricanes near landfall are, this is an urgent area of scientific inquiry. For a counterpoint on the subject, see Stoat: "only now we've had an otherwise unexciting hurricane distinguished only by rapid intensification is anyone interested in RI." Actually, I've long been interested in "RI".....
