1975 New York Times: "Climate Changes Called Ominous,", June 19, 1975 - Excerpt: “The most drastic potential change considered in the new report is an abrupt end to the present interglacial period of relative warmth that governed the planet's climate for the past 10,000 years. [...] The report also noted that periods of benign climate comparable to the present are unusual and have existed for about 8 percent of the last 700,000 years.”

1974 New York Times: "Climate Changes Endanger World's Food Output,", August 8, 1974 – Excerpt: A recent meeting of climate experts in Bonn, West Germany, produced the unanimous conclusion that the change in global weather patterns pose a severe threat to agriculture that could lead to major crop failures and mass starvation. [...] The drop [in global temps] since the 1940s has only been half a degree, but some scientists believe this is enough to trigger changes that could have important effects on the world's weather and agriculture.

1975 New York Times: "Scientists Ask Why World Climate is Changing, Major Cooling May Be Ahead", May 21, 1975 – Excerpt: Sooner or later a major cooling of the climate is widely considered inevitable. Hints that is may already begun are evident. The drop in mean temperatures since 1950 in the Northern Hemisphere has been sufficient, for example, to shorten Britain's growing season for crops by two weeks.

1974 Time Magazine: "Another Ice Age," June 24, 1974 - Excerpt: However widely the weather varies from place to place and time to time, when meteorologists take an average of temperatures around the globe they find that the atmosphere has been growing gradually cooler for the past three decades. The trend shows no indication of reversing. Climatological Cassandras are becoming increasingly apprehensive, for the weather aberrations they are studying may be the harbinger of another ice age. [...] Man, too, may be somewhat responsible for the cooling trend. The University of Wisconsin's Reid A. Bryson and other climatologists suggest that dust and other particles released into the atmosphere as a result of farming and fuel burning may be blocking more and more sunlight from reaching and heating the surface of the earth. [...] Whatever the cause of the cooling trend, its effects could be extremely serious, if not catastrophic. Scientists figure that only a 1% decrease in the amount of sunlight hitting the earth's surface could tip the climatic balance, and cool the planet enough to send it sliding down the road to another ice age within only a few hundred years.
