I agree that the science of frequency is not near settled, with even contradictory studies coming out. But the intensity of storms does seem to be increasing. Even then, if consensus emerges there will be people who don't accept it.
It's interesting to find information on what was being forecast 10 or 15 years ago, and compare to what is happening now. I think the evidence will simply become overwhelming, even for the most determined skeptic, within the next decade.
