The Doomsday Clock is an internationally recognized design that conveys how close we are to destroying our civilization with dangerous technologies of our own making. First and foremost among these are nuclear weapons, but the dangers include climate-changing technologies, emerging... Read More
With the nuclear-weapon states and their allies headed away from the increased security a world without nuclear weapons would bring, it is time for the world’s citizens and non-governmental organizations to play a leading role in creating the architecture of our future security environment. We must act now to create a multilateral plan for verifiable nuclear disarmament by the year 2045, 100 years after the first use of nuclear weapons.
Renowned graphic designer Michael Bierut has called the Bulletin’s Doomsday Clock the most powerful piece of information design of the 20th century, and last week’s Clock announcement showed its impact to have continued—and grown—well into the 21st.

In keeping the hands of the Doomsday Clock at three minutes to midnight, the members of the Bulletin of the Atomic Scientists Science and Security Board mean to make a clear statement: The world situation remains highly threatening to humanity, and decisive action to reduce the danger posed by nuclear weapons and climate change is urgently required.
A typhoon was coming, the fuel pump failed, they had to switch planes, things were wired incorrectly, they missed their rendezvous, they couldn’t see the primary target, they ran out of gas on the way home, and they had to crash-land. But the worst part was when the Fat Man atomic bomb started to arm itself mid-flight.
At three minutes to midnight on the Bulletin’s Doomsday Clock, the time has come to consider constructive steps on the multilateralization of nuclear arms control negotiations that lead toward disarmament.

Today, more than 25 years after the end of the Cold War, the members of the Bulletin of the Atomic Scientists Science and Security Board have looked closely at the world situation and found it so threatening that the hands of the Doomsday Clock must once again be set at three minutes to midnight.

A careful review of threats leads the Bulletin's Science and Security Board to conclude that the risk of civilization-threatening technological catastrophe remains high, and that the hands of the Doomsday Clock should therefore remain at five minutes to midnight.

Editor's note: Founded in 1945 by University of Chicago scientists who had helped develop the first atomic weapons in the Manhattan Project, the Bulletin of the Atomic Scientists subsequently created the Doomsday Clock in 1947 using the imagery of apocalypse (midnight) and the contemporary idiom of nuclear explosion (countdown to zero), to convey threats to humanity and the planet.
Over the past 50 years, dozens of articles have appeared in the Bulletin of the Atomic Scientists on the Cuban Missile Crisis. And with each passing year, new and relevant information has been reported -- which, for better or worse, has taught readers that the world was closer to full-scale nuclear war than was originally thought.
Earlier this month, widespread inaction on the increasing dangers posed by nuclear proliferation and climate change forced the Bulletin's Doomsday Clock to move one minute closer to midnight, indicating the mounting perils confronting humanity's survival. One factor pushing the clock forward to five minutes to midnight was the failure to ensure strict security and comprehensive international oversight for nuclear weapons and materials, which continue to accumulate in a few nations.
When dreadful events occur, reporters, readers, and interested citizens contact the Bulletin of the Atomic Scientists asking whether we will move the minute hand of the Doomsday Clock. The alarming nuclear disaster at the Fukushima Daiichi Power Station on March 11 prompted e-mails and calls to our office seeking the Bulletin's reaction as well as accurate information about what was happening in Japan.
