How long do we have before humanity destroys itself? We will soon find out, as scientists from the Bulletin of the Atomic Scientists are set to unveil the 2023 Doomsday Clock on Tuesday.

The Doomsday Clock is a visual representation of how close mankind is to self-annihilation, where midnight represents the eruption of a total global catastrophe. The clock is updated every year by members of the Bulletin's Science and Security Board to reflect whether the events of the past 12 months have pushed humanity closer or further away from destruction.
