The Doomsday Clock is a design that warns the public about how close we are to destroying our world with dangerous technologies of our own making. It is a metaphor, a reminder of the perils we must address if we are to survive on the planet.

The Clock is set by the Bulletin’s Science and Security Board (SASB), which is a select group of globally recognized leaders with a specific focus on nuclear risk, climate change, and disruptive technologies. The SASB provides the Bulletin with objective external perspectives on trends and issues in these fields and connects the organization to outside experts.

Last year, the Clock was reset at 90 seconds to midnight, the closest to midnight the Clock has been in its nearly 80 years of existence.
