One-third of Arctic sea ice disappeared between 1890 and 1940 when CO2 levels were below 310 PPM.
The facts wreck global warming theory, so NASA quite predictably responded by erasing the 1940’s Arctic warmth.

There are many indications that the 1940s were as warmer or warmer than the present, and that government climate scientists intentionally erased the warmth.
Global warming is not about science. It is about billions of dollars of government funding corrupting academia.
