How dependent are your results and conclusions on the starting point?  I you go back to 1900 and have to include the Galveston hurricane, the hurricanes of the 1930s and 1960s, the Dust Bowl of the 1930s and the floods of the 1930s, won't you end up showing that over the last 12 decades, there has actually been an appreciable decrease in the frequency and severity of weather events, wildfires, floods, and dust storms?.
