Scientists warned that humanity is closer than ever to catastrophe following the latest reset of the Doomsday Clock.

The Bulletin of the Atomic Scientists set the clock at 85 seconds to midnight, advancing it four seconds and marking the closest point since its creation in 1947.

The group cited rising catastrophic risks and a global failure of leadership as key reasons for the change.

Bulletin leaders stressed that cooperation is declining, time is running out, and urgent action from world leaders—especially in the United States, Russia, and China—is critical, USA Today has reported.

The Doomsday Clock serves as a symbolic call for governments and citizens to confront human-made existential threats and move the world away from disaster.
