If present trends continue, the world will be about four degrees colder for the global mean temperature in 1990, but eleven degrees colder by the year 2000. … This is about twice what it would take to put us in an ice age.
—Kenneth E.F. Watt on air pollution and global cooling, Earth Day (1970)
The continued rapid cooling of the earth since WWII is in accord with the increase in global air pollution associated with industrialization, mechanization, urbanization and exploding population.
—Reid Bryson, “Global Ecology; Readings towards a rational strategy for Man”, (1971) <———-Hey that’s the same reason we’re told we’re warming!
Nigel Calder (1975): The threat of a new ice age must now stand alongside nuclear war as a likely source of wholesale death and misery for mankind.(writer for Science)
Certain signs, some of them visible to the layman as well as the scientist, indicate that we have been watching an ice age approach for some time without realizing what we are seeing… Scientists predict that it will cause great snows which the world has not seen since the last ice age thousands of years ago.
- Betty Friedan, “The coming Ice Age”, Harper’s Magazine, Sept, 1958(psycologist)
An increase by only a factor of 4 in the global aerosol background concentration may be sufficient to reduce the surface temperature by as much as 3.5 deg. K. If sustained over a period of several years, such a temperature decrease over the whole globe is believed to be sufficient to trigger an ice age. – S.I Rasool and S.H. Schneider

Dr. Earl W. Barrett of ESSA
“The possibility of a new man-made, life-destroying ice age was reported by Environmental Science Services Administration (ESSA). It quoted Dr. Earl W. Barrett of ESSA Research Laboratories, Boulder, Colo., as saying the planet’s total environment “is being altered, perhaps disastrously and irreversibly, by human activities.”
Paul Cato meteorologist
“If man keeps piping pollution into the atmosphere, he could bring on a new Ice Age that would cover states like Florida with 400 feet of water, television meteorologist Paul Cato told the High Noon Club here yesterday.”
Marine Geologist Cesare Emiliani of the University of Miami,
In what direction will the earth’s climate then turn? Emiliani refuses to speculate. But if man continues his “interference with climate through deforestation, urban development and pollution,” says Emiliani in typical scientific jargon, “We may soon be confronted with either a runaway glaciation or a runaway deglaciation, both of which would generate unacceptable environmental stresses.”<——–The money quote!
Most of the full studies are behind paywalls, so we’re stuck with abstracts.

<———GW article that acknowledges the dominant past concern of global cooling!
“The world’s inhabitants, including Scientists, live primarily in the Northern Hemisphere. It is quite natural to be concerned about events that occur close to home and neglect faraway events. Hence, it is not surprising that so little attention has been given to the Southern Hemisphere. Evidence for global cooling has been based,……….”
The difference between the global cooling alarm and the global warming alarmism? The method of delivery is more sophisticated. The ability to propagandize has been enhanced by psuedo-scientists. Well, my alarm is that they are learning from their failures of the past.
