Who decides the time of the Doomsday Clock?

The decision to move (or to leave in place) the minute hand of the Doomsday Clock is made every year by the Bulletin’s Science and Security Board of Sponsors, which includes 13 Nobel Laureates. The Board meets twice a year to reflect on international events considered dangerous to mankind and rest the clock accordingly.

“Midnight” has a deeper meaning to it besides the constant threat of war. There are various things taken into consideration when the scientists from The Bulletin of the Atomic Scientists decide what Midnight and “global catastrophe” really mean in a particular year. They might include “politics, energy, weapons, diplomacy, and climate science”; potential sources of threat include nuclear threats, climate change, bioterrorism, and artificial intelligence. Members of the board judge Midnight by discussing how close they think humanity is to the end of civilization. In 1947, during the Cold War, the Clock was started at seven minutes to midnight.
