August 21 used to be a hot day in the Midwest, but has cooled dramatically over the last century. There hasn’t been a 100 degree day in the Midwest in 15 years, but they used to be quite common. On this date in 1900, Du Quoin, Illinois was 111 degrees.
On this date in 1955, the average afternoon temperature in the Midwest was 95 degrees. Average afternoon temperatures have dropped three degrees since the 19th century.
On this date in 1955, 85% of the Midwest was over 90 degrees.
Prior to 1960, summer used to last about ten days longer in the Midwest than it does now.
Midwest summers also start about five days later now than they did in the 19th century.
The frequency of hot days is down more than 50% over the past century.
The “Union of Concerned Scientists” claims the exact opposite, because their agenda has nothing to do with science or reality.
