The Doomsday Clock has been ticking for 76 years. But it’s no ordinary clock.
It attempts to gauge how close humanity is to destroying the world.
On Tuesday, the clock was set at 90 seconds until midnight — the closest to the hour it has ever been, according to the Bulletin of the Atomic Scientists, which created the clock in 1947. Midnight represents the moment at which we will have made Earth uninhabitable for humanity. From 2020 to 2022, the clock was set at 100 seconds to midnight.
