Nuclear Winter Revisited



A “major nuclear exchange” between the United States and the Soviet Union could inject enough smoke and dust into the atmosphere to cause significant temperature drops over the northern temperate zone that could last from weeks to months, according to a new study by the National Research Council (NRC).

The results of the NRC study are “consistent with the results that came out of the TTAPS study” released late in 1983, according to George Carrier, chairman of the NRC study committee. The TTAPS study—named for authors R. P. Turco, O. B. Toon, T. P. Ackerman, J. B. Pollack, and Carl Sagan—investigated the potential global atmospheric and climatic consequences of nuclear war.
