It is curious that the most acute moment in the nuclear confrontation between the USSR and the USA, the Cuban Missile Crisis of 1962, did not affect the position of the Clock hands, as it was resolved relatively quickly and without negative consequences.
1968 - The time was again reduced to seven minutes to midnight, in part due to nuclear weapons testing in China and France.
1969 - The clocks were moved back three minutes to ten minutes to midnight following the signing of the Nuclear Non-Proliferation Treaty by many countries.
1972 - The clock returned to 12 minutes to midnight after the signing of two more Soviet-American agreements: SALT I and the ABM Treaty.
1974 - The clock hands moved forward three minutes oman mobile database to nine minutes to midnight, in part because of a nuclear weapons test in India.
1980 - The clock moved two minutes closer to midnight, to seven minutes past midnight, after the US Congress refused to ratify the SALT II treaty after the war in Afghanistan began.
1981-1984 - As a result of the escalation of Soviet-American relations under President Ronald Reagan, the clock hands were moved forward in two stages to three minutes to midnight.
1988 - The clock rolled back to six minutes to midnight following the signing of the Intermediate-Range Nuclear Forces Treaty.
1990-1991 - After the collapse of the USSR and the end of the Cold War, the Clock's hands were at 17 minutes to midnight - a record low for the entire existence of the project.
1995-1998 - As tensions increased around the world, the clocks were reset first to 14 and then to nine minutes to midnight - the latter following simultaneous nuclear tests in India and Pakistan.
2002 - Due to the US withdrawal from the ABM Treaty following the September 11 attacks, the clock time shifted to seven minutes to midnight.
2007 - After North Korea's nuclear tests, the clock showed five minutes to midnight. This year, climate change was also added to the list of global threats for the first time.
2010 - The ratification of the New START Treaty between Russia and the United States, as well as the UN Climate Change Conference in Copenhagen, moved the clock hands back one minute, to six minutes to midnight.
2012-2018 — In four stages, the Clock returned to its worst position in history, showing two minutes to midnight. This was due to a general increase in global tensions, as well as the US withdrawal from the Intermediate-Range Nuclear Forces Treaty and the Paris Climate Agreement under Donald Trump. In addition, information warfare, synthetic biology and artificial intelligence were added to the list of global threats.
2020 — Two years later, the Clock set a new anti-record — 100 seconds to midnight. In particular, this happened due to the final termination of the Intermediate-Range Nuclear Forces Treaty between Russia and the United States.
2023 — The new anti-record of time on the Clock was 90 seconds past midnight. This happened due to the start of the SVO in Ukraine, as well as the suspension of Russia's participation in the START-III Treaty. In January 2024, the hands on the Clock remained in the same position.
2025 — The Doomsday Clock has been moved to 89 seconds before "nuclear midnight." That's closer than ever before.
