On This Day: The journal ‘Science’ publishes first report on nuclear winter

Residents of Earth receive a chilling early Christmas present on December 23, 1983, when a group of scientists including Carl Sagan releases a paper titled “Nuclear Winter: Global Consequences of Multiple Nuclear Explosions.” This publication introduces the concept of nuclear winter, a period of global cold and darkness that could result from a nuclear war.

The paper reported the results of modeling which showed that a war in which multiple nuclear weapons were deployed would have profound effects on the Earth’s atmosphere. The central claim was that nuclear explosions could create a cloud of dust, smoke, ash, and debris large enough to encircle the Earth and significantly lower global temperatures, spreading dangerous amounts of radiation. The authors argued that such an event would endanger all life on Earth, writing “when combined with the prompt destruction from nuclear blast, fires, and fallout and the later enhancement of solar ultraviolet radiation due to ozone depletion, long-term exposure to cold, dark, and radioactivity could pose a serious threat to human survivors and to other species.”
