According to GISS, NOAA, and CRU, the 1970’s were much warmer than the 1920’s. Yet we know that the Arctic was rapidly melting in the 1920’s and was rapidly freezing in the 1970’s.
According to global warming theory, the Arctic amplifies warming or cooling, and in fact Arctic temperatures dominate the GISS and Had-Crut v4 temperature record. That makes the claimed relative positioning of the 1920’s and 1970’s temperatures impossible.

Climate Change and its Effect on World Food
by Walter Orr Roberts
National 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 ….. The Earth may have entered a new “little ice age”.

The CIA said that the Arctic was freezing up in the 1970’s
Early in the 1970s, a series of adverse climatic anomalies occurred. …. The world’s snow and ice cover increased by 10-15%.

The IPCC said that the Arctic was freezing up in the 1970’s. The graph below is from the 1990 IPCC report, and shows Arctic sea ice satellite data which is conveniently omitted from NSIDC graphs that start at the 1979 peak.

Climatologists were so worried about the expanding Arctic ice in the 1970s, that they wanted to melt it.
Climatologists are pessimistic that political leaders will take any positive action to compensate for the climatic change, or even to allay its effects. They concede that some of the more spectacular solutions proposed, such as melting the Arctic ice cap by covering it with black soot or diverting arctic rivers, might create problems far greater than those they solve.

By contrast, The Weather Bureau said that the Arctic was melting down in the 1920’s.
NOVEMBER, 1922. MONTHLY WEATHER REVIEW
THE CHANGING ARCTIC.
The Arctic seems to be warming up. Reports from fishermen, seal hunters, and explorers who sail the seas about Spitsbergen and the eastern Arctic, all point to a radical change in climatic conditions, and hitherto unheard-of high temperatures in that part of the earth’s surface.
Many old landmarks are so changed as to be unrecognizable- Where formerly great masses of ice were found, there ore now often moraines, accumulations of earth and stones. At many points where glaciers formerly extended far into the sea they have entirely disappeared.
The change in temperature, says Captain Ingebrigtsen, has also brought about great change in the flora and fauna of the Arctic. This summer he sought for white fish in Spitsbergen waters. Formerly great shoals of them were found there. This year he saw none, although he visited all the old fishing grounds.
There were few seal in Spitsbergen waters this year, the catch being far under the average. This, however, did not surprise the captain- He pointed out that formerly the waters about Spitsbergen held an even summer temperature of about 3 Celsius; this year recorded temperatures up to 15, and last winter the ocean did not freeze over even on the north coast of Spitsbergen.

This meltdown continued until the early 1950’s. By 1947, the Arctic had warmed ten degrees and was melting “catastrophically.”

May, 1940
By far the largest number of local glaciers in north-east Greenland had receded very greatly during recent decades, and it would not be exaggerating to say that these glaciers were nearing a catastrophe.
