Gavin Schmidt : Erasing The Unanimous Global Cooling Consensus

In 1975, the National Academy of Sciences showed about 0.5C cooling in the Northern Hemisphere from 1938 to 1968.

1975 National Academy Of Sciences Report

A 1977 surface station study reported in Nature, showed the same thing.  This was confirmed by atmospheric measurements at NOAA and the German weather office.

The report, prepared by German, Japanese and American specialists, appears in the Dec. 15 issue of Nature, the British journal. The findings indicate that from 1950 to 1975 the cooling, per decade, of most climate indexes in the Northern Hemisphere was from 0.1 to 0.2 degrees Celsius, roughly 0.2 to 0.4 degrees Fahrenheit.

There was unanimous consensus of scientists that the Earth was cooling.

Arctic ice was expanding, worrying the US and Soviet Union.

Norwegian glaciers were growing for the first time in 200 years.

The National Center for Atmospheric Research confirmed this global cooling trend.

The cooling was indisputable.

This cooling wrecked the global warming story, so Gavin Schmidt at NASA has almost completely erased the indisputable global cooling trend.


The image below overlays the NASA graph on the 1975 National Academy of Sciences graph. Note that the two graphs are nearly identical until 1940, but after 1940 there is a very sharp divergence.

People like Gavin Schmidt understand that they can doing this sort of data tampering, because people don’t remember the past. All they have to do is say they are making the data better, and that the changes are all peer-reviewed.

But is is fake data, fake science and fake news. It is intended to deceive the public and corrupt public policy.

    One of the non-highlighted sections from an above clip says:

    Data from the Southern Hemisphere …. are so meager that reliable conclusions are not possible.

    Let me guess, today our good friends in government say the Southern Hemisphere has been warming.

    RE:UK SEA TEMP NOW (Bournemouth Pier)
    So has NOAA got it right at a WARM 11.1degC
    the daily- dipped
    thermometer of
    SURFER CO. at a COOL 9.8degC
    (Clue) My big toe sez………………………………………..C.!!!

    From 1976:

    If recent northern hemispheric cooling trends continue a climate of the little ice age type may occur within the next half-century

  5. Eric Simpson says:

    Clearly according to the National Academy of Sciences the Northern Hemisphere was up to a half degree colder than ~ 1940. The NH makes up 64% of the land, and as reported the data from the Southern Hemisphere is too meager to be draw conclusions from. So essentially the NH data has to stand for the entire world.

    What’s more, the best and most extensive data from the 1930s came from the USA, so the greatest weight should be given to the US data as it is much more reliable than the rest of the world’s sparse data. Well, there’s an even starker difference in temperature between the US in the ’30s and in the US in 1999 as NASA reported. Indeed, from the high in the 1930s to the low in 1978 we see that it was nearly a full 2.5°C colder in the 1930s in the USA:

    • Gail Combs says:

      Also the 1998 El Nino was a full half degree colder than the 1930s which means 2016 is also over 1/2 degree colder.

    Everyone in the Cabinet needs a crash course from The Deplorable Climate Science Blog…

    “Do you have any reason to doubt the assessment of those CIA analysts?”…Yes because 40 years ago they predicted Global Cooling.
