The Mid-20th Century Cooling: A Hidden Decline?

The La Niña dominated period from 1944-1977 caused a “global cooling” frenzy very similar to the current Global Climate Warming Change Disruption fraud…

Global Cooling: 1954-1976

The ice age is coming, the sun’s zooming in
Engines stop running, the wheat is growing thin
A nuclear era, but I have no fear
’Cause London is drowning, and I live by the river

– The Clash “London Calling,” released in 1979


The Nov. 15, 1969, “Science News” quoted meteorologist Dr. J. Murray Mitchell Jr. about global cooling worries. “How long the current cooling trend continues is one of the most important problems of our civilization,” he said.

If the cooling continued for 200 to 300 years, the earth could be plunged into an ice age, Mitchell continued.

Six years later, the periodical reported “the cooling since 1940 has been large enough and consistent enough that it will not soon be reversed.”

A city in a snow globe illustrated that March 1, 1975, article, while the cover showed an ice age obliterating an unfortunate city.

In 1975, cooling went from “one of the most important problems” to a first-place tie for “death and misery.” “The threat of a new ice age must now stand alongside nuclear war as a likely source of wholesale death and misery for mankind,” said Nigel Calder, a former editor of “New Scientist.”

He claimed it was not his disposition to be a “doomsday man.” His analysis came from “the facts [that] have emerged” about past ice ages, according to the July/August International Wildlife Magazine.

The idea of a worldwide deep freeze snowballed.


Fire and Ice: Journalists have warned of climate change for 100 years, but cant decide weather we face an ice age or warming

Energy and Climate: Studies in Geophysics was a 1977 National Academies publication. It featured the following temperature chart, which clearly shows a mid-20th century cooling trend…

The current instrumental temperature data show no significant mid-20th century cooling trend…

The late 1970′s instrumental temperature data clearly showed a mid-20th century cooling trend. The mid-20th century trend depicted in Budyko (1969) looks a lot like the HadCRUT3 cooling trend from 1878-1911…

If I substitute the 1878-1911 cooling trend for the 1944-1977 flat trend, HadCRUT3 would have very little in the way of a secular trend…

Why did the mid-20th century cooling vanish sometime between 1977 and 2010?

The warming trend since 1977 looks like an almost exact replication of the 1911-1944 warming trend…

Proxy data (tree ring data, oxygen isotopes, etc.) clearly show the mid-century cooling. Part of the Climate gate scandal was the use of Mike’s Nature Trick to hide that decline because it disagreed with the instrumental data. But the really funny thing… The instrumental data showed that decline back in the 1970’s. 

Were the contemporary reports of mid-20th century global cooling wrong?  Or was this another case of “Hide the Decline?”

    “Shhhhh.. Ve don vant anyvon to know vat is happining, zay vill be too scared to get out ov zee bed in ze morning… but, on zecond thought, zat would reduce CO2 vouldn’t it? Ya ya ya, you have givven me an idea, I can save ze vourl and get a Nobel Prize, zank you zank you zank you!” (SarkOff)

    Ain’t Science (and Modern Psyence) just the best thing since sliced bread was discovered?
