cycle or globle warming

for the last few weeks I have been doing a lot of research into hurricanes hitting my state of New Jersey. In this research I have noticed a few things that struck me kinda odd. on the avg of every 9 to 11 years there more hurricanes, the last big outbreak was in 2005 with 28 named storms. I looked back as far as in the 1800, for as much data as I could find. True going back that far was hard, and not many true records where kept in that time. Mostly first hand accounts..

Seeing this also got me looking into tornados as well, and I found the same thing. on avg every 9 to 11 yrs there is also a big break out like there has been this year.

Seeing all this has made me really think, Could this be just a normal Cycle that mother nature goes through? or could it be this so called globle warming? or maybe a little of both? That's a question that really has no answer I feel. because there is no real data from way back then to put up with all the computers and data kept today.

But seeing all this, really has to make you think too, Are we as the human race hurting out earth with all of our polution?
or is this just a cycle? You can make your own guess of this, and thats all it really is, its just a guess.

It's not just about Hurricanes and Tornados though. The heat waves, all the rain droughts. I bet if we all did a little checking on all of this we would find that there is a pattern to be found in all of this.
