The Old "Scientific Consensus" about climate change
Ah, the good old days of the early 1970's, when NASA scientists predicted that burning fossil fuels would lead to global cooling.

On July 9, 1971, the Post published a story headlined "U.S. Scientist Sees New Ice Age Coming." It told of a prediction by NASA and Columbia University scientist S.I. Rasool. The culprit: man's use of fossil fuels. The Post reported that Rasool, writing in Science, argued that in "the next 50 years" fine dust that humans discharge into the atmosphere by burning fossil fuel will screen out so much of the sun's rays that the Earth's average temperature could fall by six degrees. Sustained emissions over five to 10 years, Rasool claimed, "could be sufficient to trigger an ice age."
