Making the heat of the 1930s disappear is very important for the global warming scam. Not only were CO2 levels low in the 1930s but atmospheric H2O levels were also very low.
The US had severe or extreme drought coast to coast in 1934, meaning low levels of the greenhouse gas H2O in the atmosphere.
And not much better in 1936.
The drought was worldwide.

The summers of 1934 and 1936 were incredibly hot across the US.
On July 25, 1934, it was 110 degrees in Kentucky, 114 degrees in Missouri, 113 degrees in Illinois, and 111 degrees in Ohio.
On July 25, 1936, it was 117 degrees in Iowa, 116 degrees in South Dakota, and 115 degrees in Nebraska.
Temperatures that hot don’t occur in the Midwest anymore so it was necessary for fraudsters at NOAA to tamper with the data and make the past heat disappear.
And they don’t do it alone. Scientists around the world colluded to make past global warmth disappear.

This is the very core of what makes climate change junk science. As early as grade school student are taught the basic concept that if the data doesn’t match the theory, either modify or scrap the theory. In climate change, the data is changed to match a politically motivated theory. That is why they can’t tolerate the records showing the extreme heat in the 1930’s when the level of CO2 was relatively low.
