Georgy Sergeyevich Golitsyn is a Russian scientist in the field of Atmospheric Physics, full member of the Academy of Sciences of the USSR since 1987, Editor-in-Chief of Izvestiya, Atmospheric and Oceanic Physics, member of the Academia Europaea since 2000. He is a member of the princely house of Golitsyn. His father is the Russian writer Sergei Mikhailovich Golitsyn.
In the 1960s studied atmospheric circulation on other planets. In 1969 he predicted the small difference between nighttime and daytime temperature on Venus and its high wind velocities. He also developed a model for study of dust storms on Mars. He was also able to show that severe forest fires in Siberia in 1915 had caused global cooling.
Golitsyn is regarded by some in Russia as the author of the nuclear winter theory, which was also developed by Vladimir Alexandrov and G.I.Stenchikov and by the authors of the so-called TTAPS study. In 1982 he became aware of the work of the Royal Swedish Academy of Sciences on the subject and attended the TTAPS review meeting with Alexandrov and Nikolai Moiseev in Cambridge, Massachusetts, in April 1983.
