1) Studies are indeed occurring, and it is not a simplistic as just "counting".  If you believe that it is, you don't understand how science works.  I was also talking about intensity, which one cannot count.  Also, there is forensic work currently underway looking at hurricane history over the last millennia.

2) There is, in fact, evidence (if you don't understand what "evidence" means, look it up) that indicates that hurricanes are getting more intense, as one would expect with a basic level of knowledge about physics.

Definitive?  No.  Evidence?  Yes.  This is how science works.
