The Weather channel - Chicken Little

I admit it. I watch The Weather Channel, but it's mostly a testament to how bad the rest of the programming is out there.

But, they've been showing their media bias. One thing that's bothered me recently is they are claiming that global warming is causing more hurricanes.

So, I found the data on the National Hurricane Center web site and decided to plot it.
As you can see, there were a lot of hurricanes, 24 in fact, that struck the US in the 1940's. 10 were major hurricanes, as designated on the Saffir-Simpson scale. There were also quite a few in late 1800's. If you look at the period after WWII, the number of hurricanes tapered off, and has been lower since that decade.
I don't know where they draw their conclusion that we are getting more and worse hurricanes. Perhaps we are, since the 1970's, but in the 1990's we've had less hit us than in previous years. You would think that if global warming were doing this (beginning in the 1960's) we would see a definite up trend. On the contrary, it appears we are in a dip, and perhaps we are at the end of a period of lower than normal hurricane activity, but there's no indication it has anything to do with "Global Warming".
