The number of tropical cyclones in categories 4 and 5 (the highest two categories) has steadily increased over the last thirty years, the number per five year period doubling in that time. The number of storms and their duration also increased, but I personally didn't find these data as convincing. Whether this is linked to increasing global temperatures is a matter of speculation, and it may be part of a longer term oscillation. In any event, it looks the like the End Is Nigh placard business is set for some solid growth.

its just a cycle. we're in the peak of a bunch of hurricanes. in 10 years, hurricanes will be rare again

Well, the last ten years have had the biggest 'peak' the North Atlantic/Caribbean has ever had on record.

 

I find this graph to be quite interesting.

I checked it out. It looks like a good source of simple-to-read graphs

I didn't know about ZFACTS.COM

 

thanks for pointing it out.

That's odd. I heard on the radio today that 1900-1950 had many more category four and five (maybe it was just five, which could possibly explain it) than 1951-onward

Why would the North Atlantic and East Pacific have a lower increase?
