This is the closest the Doomsday Clock has ever been to global catastrophe, surpassing even the Cuban Missile Crisis and the peak of the Cold War. But what is this ominous number truly telling us?
We break down the powerful symbol that is the Doomsday Clock. It is a metaphor, with midnight representing civilization's absolute worst-case scenario. Created by the very scientists of the Manhattan Project—including Albert Einstein—who felt a profound responsibility to warn humanity, the clock is not a specific prediction. It is a giant, blaring alarm bell set by the Bulletin of the Atomic Scientists, urging leaders and the public to wake up and change course.
We trace the clock's journey from its launch in 1947 at $7$ minutes to midnight, to its most optimistic setting of $17$ minutes in $1991$ when the Cold War ended. Now, at 89 seconds, the danger is unprecedented. The board, which includes Nobel laureates, looks at three main threats:
The Ever-Present Nuclear Risk (the clock's original purpose).
The Crisis of Climate Change.
The Tricky Dangers from Disruptive Technologies (like AI and bio threats).
To truly understand the clock’s warning, we return to its roots. The threat of nuclear war can feel abstract, so we deconstruct the four specific ways a nuclear weapon could actually be used, based on research from a UN institute:
Doctrinal Use: The planned, calculated decision to use a nuke as part of official military strategy (e.g., in retaliation).
Escalatory Use: The classic slippery slope, where a conventional war goes badly, and one side uses a nuclear weapon to avoid losing. The Cuban Missile Crisis provides a chilling example of this near-catastrophe.
Unauthorized Use: The nightmare scenario where the official chain of command breaks down (e.g., a rogue general or a terrorist group).
Accidental Use: A catastrophic mistake, like a computer glitch, human error under pressure, or a cyber attack. We reveal that the US military has a code name for these near-misses: Broken Arrows, with declassified files showing planes carrying nukes have crashed and bombers have accidentally dropped them.
The point of breaking down these risks is not to make us feel hopeless, but to identify specific problems so we can find specific solutions. The clock is a call to action. We look at practical steps from the Federation of American Scientists, such as opening communication lines with China, adding more checks and balances to prevent rash decisions, and extending the life of current weapons instead of pouring hundreds of billions into building new ones.
As the chairman of the board, Daniel Holtz, puts it: countries are collectively choosing to pour money into weapons that could destroy civilization. The hands on the Doomsday Clock are moved by human decisions, which means we can move them back. The clock is asking all of us a very direct question: Will we choose to act in time?
