There is an enduring popular myth that in the 1970s the substantial majority of scientific opinion was predicting �global cooling� in the form of an �imminent� ice age. This myth is invoked by global warming skeptics to assert that current work on global warming represents a flip-flop by scientists and must therefore be invalid. While there were some lay articles and books published during this era that inappropriately blurred timescales to give the impression that a new ice age could occur in a matter of a decade or so, global cooling was never a widely accepted climate change paradigm among scientists working in the field. Indeed, our search of the peer-reviewed literature from 1965 to 1979 only turned up two articles projecting cooling while 13 times as many articles projected warming.
