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.
Every major climate organization endorsed the ice age scare, including NCAR, CRU, NAS, NASA – as did the CIA.
In the last decade, the Arctic ice and snow cap has expanded 12 per cent, and for the first time in this century. ships making for Iceland ports have been impeded by drifting ice.

WEATHER: The Big Freeze
Why had the rain turned white? Startled millionaires wintering in their baronial mansions in West Palm Beach, Fla., peered closer last week at the miracle that was falling from the skies and discovered—could it be?—yes, the substance was snow, the first ever reported there. Since mid-November, pedestrians in Dallas, unaccustomed to such hazards, have been slipping on sleet-slicked sidewalks. Meanwhile, a series of blizzards has smothered Buffalo this winter with an astonishing 126.6 in. of snow.
From the Dakotas and Minnesota, across the icy Great Lakes of the Middle West and down…
Climate Change and its Effect on World Food
by Walter Orr Roberts Aspen Institute for Humanistic Studies, andNational Center for Atmospheric Research, Boulder, Colorado
In February of 1972 earth-orbiting artificial satellites revealed the existence of a greatly increased area of the snow and ice cover of the north polar cap as compared to all previous years of space age observations. Some scientists believe that this may have presaged the onset of the dramatic climate anomalies of 1972 that brought far-reaching adversities to the world’s peoples. Moreover, there is mounting evidence that the bad climate of 1972 may be the forerunner of a long series of less favorable agricultural crop years that lie ahead for most world societies. Thus widespread food shortages threaten just at the same time that world populations are growing to new highs. Indeed, less favorable climate may be the new global norm. The Earth may have entered a new “little ice age”
There are strong signs that these recent climate disasters were not random deviations from the usual weather, but instead signals of the emergence of a new normal for world climates.
If we are, indeed, experiencing a worsening of world climates it is, perhaps, equal in severity to any within the last millenium. The arguments for this view were developed by several of the climatologists who attended an international workshop on climate and its effects on human life convened in May 1974 in Bonn, Germany.
At this meeting Profs. H. Flohn of Germany, H.H. Lamb of the United Kingdom and Reid Bryson of the United States developed a highly persuasive demonstration that there has been a steady cooling of northern hemisphere temperatures during the last 30 years, with the strongest cooling at the higher latitudes.
