The end of summer used to frequently be hot in the US prior to 1950.
On this date in 1895, 45 percent of the country was over 90 degrees, and it was 103F in Ohio and 102F in New Jersey.
This graph shows how dramatically the end of summer has cooled in Ohio.
Temperatures over 100 degrees during September were common in Ohio prior to 65 years ago, but there have been none in the last 65 years.
Surprisingly, no one mentioned this at yesterday’s climate strike.
