In 1975, the National Academy Of Sciences published the graph below of the Northern Hemisphere, showing about 0.5ºC cooling from the 1930’s to the 1960’s.
But NASA has kindly reduced that cooling to less than 0.2ºC
The next graph overlays the NASA graph on the National Academy of Sciences graph. NASA cleverly erased the entire inconvenient warm period from 1910 to 1940.
I say, hats off to the Ministry of Truth.
