The Bulletin of the Atomic Scientists is preparing to announce the setting of the Doomsday Clock for 2026, a symbolic measure of humanity’s proximity to global catastrophe. The announcement will take place on January 27, 2026, during a live press conference at 10:00 am ET (1500 GMT), which will be broadcast on the Bulletin’s YouTube channel. The organization encourages the public to register for email alerts to stay updated on the Clock’s position and related news.
In 2025, the Doomsday Clock was set at 89 seconds to midnight, the closest it has ever been in its 78-year history. The time is decided by the Bulletin’s Science and Security Board (SASB), a group of internationally recognized experts in nuclear risk, climate change, and emerging technologies. Their decision is made in collaboration with the Bulletin’s Board of Sponsors, which includes eight Nobel Laureates. The Clock serves as a stark warning about the threats posed by dangerous technologies, emphasizing the urgent need for global attention to avoid self-destruction.
The threat of nuclear weapons has been a primary concern since their inception 75 years ago, peaking during the Cold War when the United States and the Soviet Union engaged in a nuclear arms race. The Bulletin has expanded its focus over the years. Since 2007, the SASB has also considered climate change and disruptive technologies when determining the Clock’s setting. Currently, five major concerns related to nuclear weapons dominate discussions about the Clock.
As the last remaining arms-control treaty between the United States and Russia approaches expiration in February 2026, both nations are modernizing their nuclear forces. This includes new warheads, bombers, missiles, and submarines, raising fears of an unregulated arms race as neither country has shown interest in renewing or replacing the agreement. Analysts warn that the absence of binding restrictions could lead to increased deployments and a surge in mistrust between the world’s two largest nuclear powers.
China is also aggressively expanding its nuclear arsenal, with projections suggesting it may match the number of intercontinental ballistic missiles possessed by the United States or Russia by the end of the decade. North Korea continues to focus on nuclear development, while India and Pakistan are enhancing their delivery systems to accommodate multiple warheads. Furthermore, Russia is undertaking a significant modernization initiative, reportedly deploying nuclear weapons in Belarus. The United States is expanding its tactical nuclear arsenal and building new manufacturing facilities. The United Kingdom has increased its warhead ceiling and is developing new submarines and warheads, while Israel is believed to be enhancing its nuclear capabilities, including plutonium manufacturing sites.
In a strategic response, the President of the United States has authorized attacks on Iran’s nuclear facilities, temporarily delaying Iran’s ability to develop a nuclear bomb. Nevertheless, this strategy has raised concerns about nuclear proliferation, as longstanding allies may question the reliability of the American “nuclear umbrella.”
With rising tensions in regions such as Ukraine, Iran, and beyond, more nations are contemplating the acquisition of nuclear weapons. Iran has exceeded the limits set by the 2015 nuclear agreement, producing 60%-enriched uranium. South Korea and Japan are viewed as potential nuclear powers, while Saudi Arabia has indicated it would pursue nuclear arms if Iran does. Poland has also expressed willingness to host U.S. nuclear weapons as a deterrent against Russia.
There is increasing concern that the United States may abandon its long-standing ban on nuclear testing. Should Washington resume explosive tests, it is anticipated that China, Russia, and other nuclear-armed nations would follow suit. Simultaneously, major powers are developing faster and more agile missiles and extending their military ambitions into outer space. Experts have raised alarms over the implications of artificial intelligence in warfare, suggesting it could lead to a more “autonomous” approach to weapons, drastically reducing decision-making time during a nuclear crisis.
As the Doomsday Clock ticks closer to midnight, the need for global cooperation and dialogue on nuclear disarmament and regulation has never been more pressing. The upcoming announcement from the Bulletin of the Atomic Scientists will serve as a critical moment for reflection on the existential threats facing humanity today.
