The scientific consensus in the 1970s about “global cooling” is a beloved argument of global-warming skeptics — and little more, says a survey of scientific literature between 1965 and 1979. During that time period, seven peer-reviewed articles supported global cooling, while 44 predicted global warming. “There was no scientific consensus in the 1970s that the Earth was headed into an imminent ice age,” says coauthor Thomas Peterson. “A review of the literature suggests that, to the contrary, greenhouse warming even then dominated scientists’ thinking about the most important forces shaping Earth’s climate on human time scales.” Glad that got cleared up.
