2025 Doomsday Clock Announcement
January 28, 2025
In setting the Clock one second closer to midnight, the Science and Security Board sends a stark signal: Because the world is already perilously close to the precipice, a move of even a single second should be taken as an indication of extreme danger and an unmistakable warning that every second of delay in reversing course increases the probability of global disaster.

FAQ
The Bulletin has reset the minute hand on the Doomsday Clock 26 times since its debut in 1947, most recently in 2025 when we moved it from 90 seconds to midnight to 89 seconds to midnight. Every time it is reset, we’re flooded with questions about the internationally recognized symbol. Here are answers to some of the most frequent queries.
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.
When the Doomsday Clock was created in 1947, the greatest danger to humanity came from nuclear weapons, in particular from the prospect that the United States and the Soviet Union were headed for a nuclear arms race. The Bulletin considered possible catastrophic disruptions from climate change in its hand-setting deliberations for the first time in 2007.

The Doomsday Clock at 75
The Doomsday Clock is many things all at once: It’s a metaphor, it’s a logo, it’s a brand, and it’s one of the most recognizable symbols in the past 100 years. It has permeated not only the media landscape but also culture itself. The Doomsday Clock appears in novels by Stephen King and Piers Anthony, songs by The Who and the Clash, and comics like Watchmen and Stormwatch.
This 75th anniversary coffee table book explores the powerful symbol of the Clock, and how it has impacted culture, politics, and global policy—and helped shape discussions and strategies around nuclear risk, climate change, and disruptive technologies.
