So what is it you're claiming? That hurricanes used to be "rare"? If that's the case, I think you should provide a definition of rare, show that they are no longer rare, and provide some data to back up your claim.
But again, rather just lazily positing a link to some zealot's article, why find a study, read it, pull out a few pertinent quotes and comment on them? That would make for a much better discussion. Until then, you have nothing.
