Increasing Hurricanes?

Ok, I finally thought of something I haven't ranted about yet.  Ever since Katrina, people have been talking about how global warming is causing hurricanes to become more frequent and more powerful, and thusly more devastating.  Ever since Katrina, there has been an eery calm in the atlantic in respect to hurricanes.  Maybe we have more named storm, but if that's so it's because they've been changing their method of collecting data, a highly unscientific method, whether they wanted to skew the data or not.  For instance, we have started naming both atlantic and pacific storms, we now have far superior technology with which to detect storms that reach the required wind-speeds while they aren't over land, or even don't hit land at all.  Since Katrina, there hasn't been any significant property damage due to hurricanes in the United States (I say significant as in worthy of being reported by the main-stream media, which is predisposed to hype anything, especially tragedies and especially especially tragedies that could have been caused by global warming).  It's really quite humorous.  Every year they predict a record hurricane season, and every year we get comparative calm.  Take this season for instance, granted it isn't over yet, but so far it's been acting pretty typically for post-Katrina season's and everyone can remember it because it's still going on.  At the beginning of the season, there were the traditional proclamations of coming hurricane doom.  Now, there is finally a hurricane that looks like it might make landfall on the US.  GOOD!  Florida, Texas and other parts of the south that often experience hurricanes are currently in severe droughts.  How does one mitigate the severity of a drought?  Get a hurricane to come through.  It's natures watering can.  They suck water up out of the ocean and dump it on the land.  The fact is, that hurricanes are a vital part of southern ecology.  Without them, you get droughts.  So I'm saying that from looking at the data, we have been going through a period of Global Cooling since hurricane Katrina.  Although I'm sure someone has already written an article in Nature about how Global warming causes both more hurricanes and less hurricanes, just like it causes both floods and droughts and both high temperatures and low temperatures.
