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.
Thanks.
This is entirely consistent with everything IPCC and the worldwide scientific community has found and reported.
There was a slight global cooling trend around the 1950s 1960s and 1970s, because of the particulate matter (soot, dust, particles) associated with the burning of fossil fuels. Particulate matter in the atmosphere reflects solar radiation, leading to climatic cooling. Particulate matter is an entirely different issue than gaseous CO2
Since your article is from 1971, Clean Air laws had not yet been enacted on large scales, to regulate and scrub particulate matter from industrial activities. In other words, your half-century old article is wildly out of date with respect to the current situation. Once particulate matter was regulated, in the 1970s and 1980s, it was less of a problem in the atmosphere - hence, it was less of a contributor to climatic cooling. In fact, its widely agreed that the cooling effect of particulate matter partly masked the heating effect of greenhouse gases in the middle part of the last century.
Scientists then slowly became aware that even though particulate matter in the atmosphere was being mitigated, that there was another issue: Greenhouse gases. Which have the opposite effect of particulate matter: they heat up (rather than cool down) the climate. Hence, in the nearly half century since particulate matter emissions were heavily regulated, another issue came to the fore: the heating properties of greenhouse gasses in the atmosphere.
