From Newsweek. Of interest, Newsweek had a cover story in 1975 titled "The Cooling World" that suggested cooling "may portend a drastic decline for food production."
A 1974 Time magazine article "Another Ice Age?" painted a similarly bleak picture:
"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."
