uh, les see...<quoted text>
Please explain your logic....I picked the year 1993 in both charts. In the first chart 1993 had 1400 weather events, in the 2nd chart it was down to 600. So tell me how by starting at 1980 instead of 1950, the year 1993 had 800 less extreme weather events.
Thirty fewer years? A difference in the size of the catastrophes, maybe?
