What the Doomsday Clock actually measures
The Bulletin of the Atomic Scientists maintains a symbolic setting, not a countdown. It gets quoted as a countdown roughly every time it is mentioned.
The Doomsday Clock is a symbolic assessment published by the Bulletin of the Atomic Scientists, revised periodically to reflect expert judgement on nuclear risk, climate change, and disruptive technologies.\n\nIt is not a timer, it does not tick in real time, and it has never predicted a date. When it moves we log the change with the Bulletin cited directly. Today's entry is context rather than news: the setting has not changed.
