Doomsday Clock

"Minutes to Midnight" redirects here, along with other titles incorporating that term. For other uses, see Minutes to Midnight (disambiguation). For the Smashing Pumpkins song, see Doomsday Clock (song).

In January 2012, the Doomsday Clock read five minutes to midnight (11:55pm).

The Doomsday Clock is a symbolic clock face, maintained since 1947 by the board of directors of the Bulletin of the Atomic Scientists at the University of Chicago. The closer the clock is to midnight, the closer the world is estimated to be to global disaster. The most recent officially-announced setting — five minutes to midnight (11:55pm) — was made on 10 January 2012. 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).

Originally, the clock analogy represented the threat of global nuclear war; however, since 2007 it has also reflected climate-changing technologies and "new developments in the life sciences that could inflict irrevocable harm."

Cover of the 1947 Bulletin of the Atomic Scientists issue that first featured the Doomsday Clock at seven minutes to midnight.

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 magazine 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.

Time 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 directors of the Bulletin of the Atomic Scientists and is an adjunct to the essays in the bulletin on global affairs. The clock has not always been set and reset as quickly as events occur; the closest nuclear war threat, the Cuban Missile Crisis in 1962, reached crisis, climax, and resolution before it could be set to reflect that possible doomsday.

Timeline of the Doomsday Clock

Year	Mins Left	Time	Change	Reason
1947	7	11:53pm	—	The initial setting of the Doomsday Clock.
1949	3	11:57pm	+4	The Soviet Union tests its first atomic bomb, officially starting the nuclear arms race.
1953	2	11:58pm	+1	The United States and the Soviet Union test thermonuclear devices within nine months of one another. (This is the clock's closest approach to midnight since its inception.)
1960	7	11:53pm	−5	In response to a perception of increased scientific cooperation and public understanding of the dangers of nuclear weapons, as well political actions taken to avoid "massive retaliation." 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.
1963	12	11:48pm	−5	The United States and Soviet Union sign the Partial Test Ban Treaty, limiting atmospheric nuclear testing.
1968	7	11:53pm	+5	Vietnam War intensifies. Six Day War occurs in 1967. Indo-Pakistani War of 1965 takes place. Worse yet, France and China acquire and test nuclear weapons (1960 (Gerboise Bleue nuclear test) and 1964 (596 nuclear test) respectively).
1969	10	11:50pm	−3	The U.S. Senate ratifies the Nuclear Non-Proliferation Treaty.
1972	12	11:48pm	−2	The United States and the Soviet Union sign the SALT I (Strategic Arms Limitation Treaty) and the Anti-Ballistic Missile Treaty.
1974	9	11:51pm	+3	India tests a nuclear device (Smiling Buddha), SALT II talks stall. Both the United States and the Soviet Union modernize MIRVs
1980	7	11:53pm	+2	Further deadlock in US-Soviet Union talks. In protest to the Soviet-Afghan War, President Carter pulls the United States from the 1980 Summer Olympics in Moscow and considers ways in which US can win nuclear war.
1981	4	11:56pm	+3	Soviet-Afghan War hardens the US nuclear posture. Ronald Reagan becomes president, scraps further arms control talks with the Soviet Union and argues that the only way to end the Cold War is to win it.
1984	3	11:57pm	+1	Further escalation of the arms race between the U.S. and the Soviet Union.
1988	6	11:54pm	−3	The U.S. and the Soviet Union sign treaty to eliminate intermediate-range nuclear forces, relations improve.
1990	10	11:50pm	−4	Fall of the Berlin Wall, dissolution of Iron Curtain sealing off Eastern Europe, Cold War nearing an end.
1991	17	11:43pm	−7	United States and Soviet Union sign the Strategic Arms Reduction Treaty. This is the clock's earliest setting since its inception.
1995	14	11:46pm	+3	Global military spending continues at Cold War levels; concerns about post-Soviet nuclear proliferation of weapons and brainpower.
1998	9	11:51pm	+5	Both India (Pokhran-II) and Pakistan (Chagai-I) test nuclear weapons in a tit-for-tat show of aggression; the United States and Russia run into difficulties in further reducing stockpiles.
2002	7	11:53pm	+2	Little progress on global nuclear disarmament; United States rejects a series of arms control treaties and announces its intentions to withdraw from the Anti-Ballistic Missile Treaty; concerns about the possibility of a nuclear terrorist attack due to the amount of weapon-grade nuclear materials that are unsecured and unaccounted for worldwide.
2007	5	11:55pm	+2	North Korea's test of a nuclear weapon, Iran's nuclear ambitions, a renewed U.S. 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.
2010	6	11:54pm	−1	Worldwide cooperation to reduce nuclear arsenals and limit effect of climate change.
2012	5	11:55pm	+1	Lack of global political action to address nuclear weapons stockpiles, the potential for regional nuclear conflict, nuclear power safety, and global climate change.

In popular culture

• Alan Moore's groundbreaking graphic novel Watchmen makes extensive use of the image of the Doomsday Clock. There are numerous overt as well as veiled references to it, often through the use of clock faces showing times close to midnight figuring in many panels throughout the book. The idea of clocks and time (especially of time running out) recurs throughout the novel, with the many-layered title itself ("Watchmen") partly being a reference to this. The book is made up of twelve chapters, with a clock face gradually approaching midnight printed on the front cover of each. Another major symbol in the novel is the smiley face, which appears mainly as a badge worn by one of the central characters (The Comedian); the book begins with The Comedian's death, with a drop of his blood having fallen on the badge in the form of a minute hand pointing to several minutes before midnight. The story is set in 1985, with Chapter 1 published in Sept 1986 – both of these dates fall within a period when the Doomsday Clock was at its most perilous point in decades – namely 3 minutes to midnight, when dialogue between the two superpowers had virtually ground to a halt; it would stay in this position from 1984 until 1988.
