Atomic Scientists Set Doomsday Clock Closer to Midnight Than Ever

Atomic scientists announced on January 27, 2026 that they have moved the Doomsday Clock closer to midnight than at any other point in history, citing escalating geopolitical tensions, fraying nuclear arms control and the rapid advancement of risky technologies.

The symbolic clock maintained by the Bulletin of the Atomic Scientists now stands at 85 seconds before midnight, a four second tightening compared with its previous setting. Scientists pointed to aggressive policies by major nuclear powers including Russia, China and the United States as factors that have increased global risk.

In a statement the group warned that conflicts around the world including the war in Ukraine the situation in the Middle East and competition in artificial intelligence have combined to create a precarious security environment. The clock was first introduced in 1947 to indicate how close humanity is to catastrophic destruction and has been adjusted periodically based on global threat assessments. 

The group urged world leaders to pursue diplomatic solutions strengthen arms control agreements and cooperate on responsible technology governance to reduce existential risk. There was particular emphasis on reengaging stalled nuclear treaties and building trust through sustained dialogue. 

Scientists also noted that public awareness and civic engagement are critical to driving political action that can avert potential disasters. They said reducing greenhouse gas emissions mitigating emerging risks and addressing geopolitical conflicts are all necessary steps to move the clock backward.
