The Doomsday Clock

Wednesday, January 24, 2024 - 10 minutes
The Doomsday Clock that has been ticking for 77 years is no ordinary clock — it attempts to gauge how close humanity is to destroying the world. On Tuesday, the clock was again set at 90 seconds to 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 people will have made Earth uninhabitable.
