In 1971, NASA and NCAR’s top climatologists knew that even a massive increase in atmospheric CO2 would produce less than 2 degrees warming. The entire basis of the catastrophic global warming scam has been known to be a fraud from day one.
This is consistent with what radiative transfer models and satellite temperatures show. Without NASA and NOAA data tampering, the entire scam would have collapsed a decade ago.
