Three Generations Of Data Tampering And Hiding The Decline
The Ice Age Cometh than the Feds disappear it as though it never happened. Good thing the records still exist that show what liars are in our government.
In 1975, the National Academy of Sciences published the Northern Hemisphere temperature graph below, which showed cooling from 1940 to 1970 back to 1910 levels.
By 1982, scientists had already eliminated much of the 1940 to 1970 Northern Hemisphere cooling
And then Hansen got a hold of it, completely changed the shape of the Northern Hemisphere plot, and almost completely eliminated the 1940 to 1970 global cooling period.
The animation below cycles through the progressive stages which government scientists have tampered with history in order to match their CO2 theory, normalized to 1920-1940
And of course there is the elimination of Briffa’s trees from the hockey stick, which showed the same decline that Hansen has erased.
Fortunately, there were quite a few real scientists from the 1970s who documented the global cooling which later Orwellian crooks tried to erase.
