October 5 used to be a warm day in the US, but temperatures have plummeted nearly five degrees since the 19th century.
There was a big drop in the area of the US affected by hot weather after 1954.
On this date in 1900, upstate New York was over 90 degrees.
On this date in 1922, much of the eastern half of the US was over 90 degrees.
The Arctic was rapidly melting that year.

On this date in 1954, much of the southeastern US was over 100 degrees, and Hurricane Hazel was forming out in the Atlantic.
The US is getting cooler, and has been for a long time. It is time for NOAA and NASA to stop tampering with data.
