If you look further back, to the years before 1940, you'll find more global warming fears. We're like cave men looking out into the rain, expecting the whole earth to flood because it has rained for days on end; then fearing drought and famine when it fails to rain over the next week.
“In the next 50 years fine dust that humans discharge into the atmosphere by burning fossil fuel will screen out so much of the sun’s rays that the Earth’s average temperature could fall by six degrees. Sustained emissions over five to 10 years, could be sufficient to trigger an ice age.” – Washington Post - July 9, 1971
“Fifth ice age is on the way…..Human race will have to fight for its existence against cold.” – Los Angles Times October 23, 1912

Scientist says Arctic ice will wipe out Canada, Professor Gregory of Yale University stated that “another world ice-epoch is due.” He was the American representative to the Pan-Pacific Science Congress and warned that North America would disappear as far south as the Great Lakes, and huge parts of Asia and Europe would be “wiped out.” – Chicago Tribune August 9, 1923
"The discoveries of changes in the sun’s heat and southward advance of glaciers in recent years have given rise to the conjectures of the possible advent of a new ice age." - Time Magazine 9/10/1923

Like an outrigger canoe riding before a huge comber, the earth with its inhabitants is caught on the downslope of an immense climatic wave that is plunging us toward another Ice Age. - Los Angeles Times December 23, 1962
The United States and the Soviet Union are mounting large-scale investigations to determine why the Arctic climate is becoming more frigid, why parts of the Arctic sea ice have recently become ominously thicker and whether the extent of that ice cover contributes to the onset of ice ages. – New York Times - July 18, 1970
The battle to feed humanity is over. In the 1970s, the world will undergo famines. Hundreds of millions of people are going to starve to death in spite of any crash programs embarked upon now. — Paul Ehrlich - The Population Bomb (1968)
Get a good grip on your long johns, cold weather haters—the worst may be yet to come. That’s the long-long-range weather forecast being given out by “climatologists.” the people who study very long-term world weather trends…. Washington Post January 11, 1970
Convection in the Antarctic Ice Sheet Leading to a Surge of the Ice Sheet and Possibly to a New Ice Age. – Science 1970
New Ice Age Coming-—It’s Already Getting Colder. Some midsummer day, perhaps not too far in the future, a hard, killing frost will sweep down on the wheat fields of Saskatchewan, the Dakotas and the Russian steppes…..Los Angles Times Oct 24, 1971
“There is very important climatic change (Global Cooling) going on right now, and it’s not merely something of academic interest. It is something that, if it continues, will affect the whole human occupation of the earth – like a billion people starving. The effects are already showing up in a rather drastic way.” – Fortune Magazine February 1974

A number of climatologists, whose job it is to keep an eye on long-term weather changes, have lately been predicting deterioration of the benign climate to which we have grown accustomed….Various climatologists issued a statement that “the facts of the present climate change are such that the most optimistic experts would assign near certainty to major crop failure in a decade,” If policy makers do not account for this oncoming doom, “mass deaths by starvation and probably in anarchy and violence” will result. New York Times - December 29, 1974
An international team of specialists has concluded from eight indexes of climate that there is no end in sight to the cooling trend of the last 30 years, at least in the Northern Hemisphere. - New York Times - January 5, 1978
