In the 1970s, there was increasing awareness that estimates of global temperatures showed cooling since 1945. Of those scientific papers considering climate trends over the next century, slightly under 10% inclined towards future cooling, while most papers predicted future warming.[2] The general public had little awareness of carbon dioxide's effects on climate, although Paul R. Ehrlich mentions climate change from the greenhouse gases in 1968.By the time the idea of global cooling reached the public press in the mid-1970s, the temperature trend had stopped going down, and there was concern in the climatological community about carbon dioxide's effects. It was known that both natural and man-made effects caused variations in global climate.
