The Doomsday Clock has been moved to 85 seconds to midnight, the closest point to global catastrophe since the clock was first introduced in 1947, the Bulletin of the Atomic Scientists announced. The decision reflects rising concerns over multiple global threats, including nuclear conflict, climate change, emerging technologies, and biological risks.
The Doomsday Clock is a symbolic representation designed to show how close humanity is to self-inflicted destruction. Midnight represents global catastrophe, while the number of seconds to midnight indicates the level of existential risk facing the world. The latest adjustment signals a worsening global security environment and highlights the urgency of coordinated international action.
According to the Bulletin’s Science and Security Board, the move was influenced by escalating geopolitical tensions, ongoing conflicts involving nuclear-armed states, and the continued modernization and expansion of nuclear arsenals. The board warned that the risk of nuclear escalation, whether intentional or accidental, remains unacceptably high.
Another major factor behind the decision is the rapid development of artificial intelligence. While AI holds significant benefits, the lack of global rules governing its military and surveillance applications poses serious risks. The board stressed the need for international guidelines to prevent misuse of AI technologies that could destabilize global security or undermine democratic institutions.
Climate change was also cited as a critical concern. Despite growing scientific evidence and repeated warnings, global efforts to reduce greenhouse gas emissions remain insufficient. Rising temperatures, extreme weather events, and environmental degradation continue to increase humanitarian and economic risks worldwide.
Biological threats, including the potential misuse of biotechnology and the lessons learned from recent pandemics, were highlighted as another area requiring urgent attention. The board called for stronger international cooperation to improve disease surveillance, preparedness, and response mechanisms.
The Doomsday Clock is set by the Bulletin of the Atomic Scientists’ Science and Security Board in consultation with its Board of Sponsors. This group includes leading experts in science, security, and policy, as well as Nobel Prize winners. Each year, they assess global developments and determine whether humanity has moved closer to or further away from existential danger.
In its latest statement, the board urged governments, international institutions, and civil society to act decisively. It emphasized the need for renewed arms control agreements, diplomatic engagement to reduce conflicts, responsible governance of emerging technologies, and stronger climate action.
The Bulletin noted that the clock’s setting is not a prediction, but a warning. It serves as a call to action, reminding global leaders and citizens that the choices made today will determine the future of humanity.
As global challenges become more interconnected and complex, the Bulletin stressed that no single country can address these threats alone. Only sustained international cooperation, trust-building, and evidence-based policymaking can push the clock away from midnight and toward a safer future.
