Who Controls the Doomsday Clock?

The Doomsday Clock is set by the Science and Security Board of the Bulletin of the Atomic Scientists, in consultation with their Board of Sponsors, which includes Nobel Laureates.

The Decision Process

Each year, the Board evaluates nuclear threats, climate change, disruptive technologies, and biosecurity to determine whether to move the clock forward, backward, or leave it unchanged.
