Doomsday Clock — 90 seconds to midnight remains on ‘global alarm’
The Doomsday Clock reads 90 seconds to midnight as it has been for the past year, which is still the closest it has ever been to striking midnight, symbolizing the end of the world.
The clock, first set up in 1947, operates as a wake-up call for the world about global threats such as nuclear war, dangerous technologies, and mass health concerns.
Science educator Bill Nye is the keynote speaker for today's event.
