NOAA data shows extreme weather was as common a century ago

The latest agitprop from AGW alarmists is that the weather has become more extreme. However, the NOAA US Climate Extremes Index shows over the 50 years 1910-1960 there were 22 years with weather extremes that exceeded the mean, compared to 20 years that exceeded the mean over the following 50 years 1960-2010. The 9 year  smoothed data was higher in 1911 than 2010, back when CO2 was "safe." Reporting of weather events has greatly improved since the early 1900's and therefore the index may underestimate the number of extreme events before the modern age.
