The Cold and the Dark is the record of the Conference on the Long-Term Worldwide Biological Consequences of Nuclear War, held in Washington, D.C., on October 31 to November 1, 1983. The conference involved over 200 scientists from many nations and drew together the best available scientific information. Its central finding was the phenomenon of nuclear winter: a much more profound and long-lasting devastation of the earth and atmosphere than had been believed possible before. In the two principal papers, Carl Sagan presents the atmospheric and climatic consequences of nuclear war and Paul Ehrlich summarizes its biological implications. Also included is the text of the “Moscow Link” —a dialogue between Soviet and American scientists on nuclear winter—and the technical papers providing the scientific evidence for the book’s conclusions.

In 1973, Carl Sagan published The Cosmic Connection, a daring view of the universe, which rapidly became a classic work of popular science and inspired a generation of scientists and enthusiasts. This seminal work is reproduced here for a whole new generation to enjoy. In Sagan's typically lucid, lyrical style, he discusses many topics from astrophysics and solar system science, to colonization of other worlds, terraforming and the search for extraterrestrials. Sagan conveys his own excitement and wonder, and relates the revelations of astronomy to the most profound human problems and concerns: issues that are just as valid today as they were 30 years ago. New to this edition are Freeman Dyson's comments on Sagan's vision and the importance of the work, Ann Druyan's assessment of Sagan's cultural significance as a champion of science, and David Morrison's discussion of the advances made since 1973 and what became of Sagan's predictions.
