The Bulletin of the Atomic Scientists equips the public, policy makers and scientists with the information needed to reduce man-made threats to our existence. At its core, it is a media organization, publishing a free-access website and a bimonthly magazine. But it is much more. The Bulletin’s website, iconic Doomsday Clock, and regular events draw attention to three main areas: nuclear risk, climate change, and disruptive technologies. What connects these is a driving belief that because humans created them, we can control them. The Bulletin is an independent, nonprofit 501 c (3) organization founded by Manhattan Project scientists nearly 75 years ago. It gathers the most informed and influential thought leaders tracking man-made threats and brings innovative thinking to a global audience. The Bulletin applies intellectual rigor to the conversation and does not shrink from alarming truths.

The Bulletin’s iconic Doomsday Clock uses the imagery of apocalypse (midnight) and the idiom of nuclear explosion (countdown to zero) to convey threats to humanity and the planet. It is currently set at 100 seconds to midnight, the closest it’s ever been to midnight. The Clock is set every year by the Bulletin’s Science and Security Board in consultation with its Board of Sponsors, which includes 11 Nobel laureates. The Clock has become a universally recognized indicator of the world’s vulnerability to catastrophe from nuclear weapons, climate change, and disruptive technologies.
