September 19 used to be a hot day in the US, but temperatures have plummeted over the past century. As with most summer days, temperatures dropped sharply after 1955.
On this date in 1925, most of the eastern US was over 90 degrees, Nebraska, Indiana, Kentucky and much of the south was over 100 degrees.
If government climate scientists were actual scientists, they would want to understand this prior warmth – rather than bury it.
But they aren’t scientists, and they have no interest in science.
