Found some rather interesting quotes about climate change here:

"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.
"The rapid cooling of the earth since World War II is also in accord with the increased air pollution associated with industrialization, and an exploding population." - Reid Bryson, "Environmental Roulette", 1971; "Global Ecology; Readings towards a rational strategy for Man", 1971.
"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, Science, v173, p138, 9/7/1971.
"There are ominous signs that the earth's weather patterns have begun to change dramatically and that these changes may portend a drastic decline in food production - with serious political implications for just about every nation on earth. The drop in food production could begin quite soon... The evidence in support of these predictions has now begun to accumulate so massively that meteorologists are hard-pressed to keep up with it." - "The Cooling World", Newsweek, April 28, 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." - Nigel Calder, International Wildlife, June 1975.
"This [cooling] trend will reduce agricultural productivity for the rest of the century" - Peter Gwynne, Newsweek 1976
"This cooling has already killed hundreds of thousands of people. If it continues and no strong action is taken, it will cause world famine, world chaos and world war, and this could all come about before the year 2000." - Lowell Ponte "The Cooling", 1976
