The Doomsday Clock is a universally recognized symbolic clock face, representing an ominous oscillating countdown to possible technology-related global catastrophe. It was maintained since 1947 by the members of the Science and Security Board of the Bulletin of the Atomic Scientists, who are in turn advised by the Governing Board and the Board of Sponsors, including 18 Nobel Laureates. The closer they set the Clock to midnight, the closer the scientists believe the world is to the global disaster.
Originally, the Clock, which hangs on a wall in a Bulletin's office in the University of Chicago, represented an analogy for the threat of global nuclear war; however, since 2007 it has also reflected climate change and new developments in the life sciences and technology that could inflict irrevocable harm to humanity. The most recent officially announced setting—five minutes to midnight (11:55pm)—was made on January 14, 2014.
The origin of the Clock can be traced to the international group of researchers called the Chicago Atomic Scientists who had participated in the Manhattan Project. After Hiroshima and Nagasaki, they started to publish a mimeographed newsletter and then a bulletin. Since its inception, the Clock has been depicted on every cover of the Bulletin of the Atomic Scientists. Its first representation was in 1947, when bulletin co-founder Hyman Goldsmith asked artist Martyl Langsdorf (wife of Manhattan Project research associate and Szilárd petition signatory Alexander Langsdorf, Jr.) to design a cover for the magazine's June 1947 issue. As Eugene Rabinowitch, another co-founder of the Bulletin, explained later,
The Bulletin's clock is not a gauge to register the ups and downs of the international power struggle; it is intended to reflect basic changes in the level of continuous danger in which mankind lives in the nuclear age...
In January, 2007, designer Michael Bierut, who was on the Bulletin's Governing Board, redesigned the Clock to give it a more modern feel. In 2009, the Bulletin ceased its print edition and was one of the first print publications in the US to become entirely digital; the Clock is now found as part of the logo on the Bulletin's website. Information about the annual Doomsday Clock Symposium, a timeline of the Clock's settings, and multimedia shows about the Clock's history and culture can also be found on the Bulletin's website.
The 5th Annual Doomsday Clock Symposium was held on November 14, 2013 in Washington, D.C.; it was a daylong event that was open to the public and featured panelists discussing various issues on the topic "Communicating Catastrophe." There was also an evening event at the Hirshhorn Museum and Sculpture Garden in conjunction with the Hirshhorn's current exhibit, "Damage Control: Art and Destruction Since 1950." The panel discussions, held at the American Association for the Advancement of Science, were streamed live from the Bulletin's website, and can still be viewed there. Reflecting international events dangerous to humankind, the Clock's hands have been adjusted twenty times since its inception in 1947, when the Clock was initially set to seven minutes to midnight (11:53pm).
Symbolic timepiece changes
In 1947, during the Cold War, the Clock was started at seven minutes to midnight and was subsequently advanced or rewound per the state of the world and nuclear war prospects. The Clock's setting is decided by the Science and Security Board of the Bulletin of the Atomic Scientists and is an adjunct to the essays in the Bulletin on global affairs. The Clock is not set and reset in real time as events occur; rather than respond to each and every crisis as it happens, the Science and Security Board meets twice annually to discuss global events in a deliberative manner. The closest nuclear war threat, the Cuban Missile Crisis in 1962, reached crisis, climax, and resolution before the Clock could be set to reflect that possible doomsday.

The United States and Soviet Union cooperate and avoid direct confrontation in regional conflicts such as the 1956 Suez Crisis. Scientists from different countries help establish the International Geophysical Year, a series of coordinated, worldwide scientific observations between nations allied with both the United States and the Soviet Union, and the Pugwash Conferences on Science and World Affairs, which allow Soviet and American scientists to interact.|

|1968||7||23:53||+5||Regional wars wage: Vietnam War intensifies, Six Day War occurs in 1967 and Indo-Pakistani War of 1965 takes place. Worse yet, France and China, two nations which have not signed the Partial Test Ban Treaty, acquire and test nuclear weapons (1960 (Gerboise Bleue nuclear test) and 1964 (596 nuclear test) respectively) to assert themselves as global players in the nuclear arms race.|

|1974||9||23:51||+3||India tests a nuclear device (Smiling Buddha), SALT II talks stall. Both the United States and the Soviet Union modernize MIRVs|
|1980||7||23:53||+2||Unforeseeable end to deadlock in American–Soviet talks as Soviet war in Afghanistan proceeds.

|1981||4||23:56||+3||The clock is adjusted in early 1981. Soviet war in Afghanistan toughens the US nuclear posture.

Tensions between the United States and the Soviet Union contributes to the danger of the nuclear annihilation.|
|1983||3||23:57||+1||The clock is adjusted in December 1983 since the ongoing Afghanistan war heats the Cold war.

|2007||5||23:55||+2||North Korea's test of a nuclear weapon, Iran's nuclear ambitions, a renewed American emphasis on the military utility of nuclear weapons, the failure to adequately secure nuclear materials, and the continued presence of some 26,000 nuclear weapons in the United States and Russia. Some scientists, assessing the dangers posed to civilization, have added climate change to the prospect of nuclear annihilation as the greatest threats to humankind.|
