Robert Oppenheimer, the director of the Manhattan Project. Specifically, the concept of nuclear winter, which was first brought to the world's attention by astrophysicist and author Carl Sagan in 1983.  Virtually…

Nuclear war could produce a huge smoke cloud known as a nuclear winter, devastating agriculture and civilisation, a study shows.

Christopher Nolan’s biopic of J. Robert Oppenheimer has revived morbid curiosity in the destructive power of nuclear weapons. There are now an estimated 12,512 nuclear warheads. A war in which even a fraction of these bombs were detonated would create blast waves and fires capable of killing millions of people almost instantly.

Dismantling what Daniel Ellsberg called the nuclear “Doomsday Machine” would involve dramatic reductions in current nuclear arsenals and consistent efforts to reduce the possibility of inadvertent war, including the institution of no-first-use policies. A more ambitious approach is the total abolition of nuclear weapons through the UN Treaty on the Prohibition of Nuclear Weapons.
