It's Almost As If Climate Is a Dynamic System

Jason at Productivity Shock did some research about hurricane activity over the past seventy years. The downward trend from the 60s to the 90s is most telling.

Note that in the original data, even the 60s didn't have two close together, suggesting why we are having an "epidemic" all of a sudden. Some one should tell climatologists that one decade does not indicate a trend.

What I'd really like to see is data for all hurricanes. But so far that search is not yielding data...

I don't understand this claim, David. On the table we can clearly see that in 1960, Donna and Ethel arrived 11 days apart, and then in 1961, Carla and Hattie were 49 days apart.

Opps! I missed that first pair. Thanks Jason.

I would claim that your second pair is relatively far apart, given its month+ span.
