When CO2 was below 350 PPM, 100ºF temperatures in Iowa were very common. Now they are quite rare – with only three recorded this summer at all long term HCN stations. Ninety-six percent of all 100ºF readings occurred when CO2 was below 350 PPM.
In 1936, Iowa recorded 466 100ºF temperature readings.
NOAA and NASA have erased the 1930s heat from their published temperature graphs. I hope they are getting paid well to destroy American history.
