On this date in 1936 (with CO2 at 310 PPM) it was 119 degrees in Kansas and 117 degrees in Nebraska. Seven states were over 110 degrees, twenty were over 100 degrees, and all but three were over 90 degrees.
Imagine the mass hysteria if we had weather that hot now. Climate scientists would declare 100% certainty that this could not happen at lower CO2 levels.
Average temperature around the US was 93 degrees. What I find remarkable in the graph below is how every year from 1933 to 1940 had extremely hot weather on this date.
