The Doomsday Clock, a chilling symbol of humanity’s proximity to global disaster, will soon have its 2025 time revealed by the Bulletin of the Atomic Scientists.
Since its creation in 1947, the clock has served as a warning, with midnight symbolizing global catastrophe.
Origins and Purpose
The Doomsday Clock was introduced in the Bulletin’s inaugural magazine edition to highlight the growing threat of nuclear weapons after World War II, particularly tensions between the United States and the Soviet Union. Over time, it has evolved to account for other risks, such as climate change and national security threats.

The clock’s position is determined annually by the Bulletin’s Science and Security Board, in consultation with its Board of Sponsors, which includes 10 Nobel laureates. The closer the clock is to midnight, the nearer the world is to disaster.
Current Status
In 2023, the clock was set to 90 seconds to midnight, the closest in its history, driven by the Ukraine war and the risk of nuclear escalation.

Challenges in 2024, such as the Israel-Hamas conflict, global political shifts, and a high-stakes U.S. election year, have further influenced global security dynamics.
Historical Changes
- 2018: Moved to two minutes to midnight.
- 2019: No change.
- 2020-2022: Edged closer, reaching 100 seconds to midnight in 2020.
- 2023: Advanced to 90 seconds, citing Russia’s invasion of Ukraine.
This year’s update is eagerly anticipated, as the clock reflects ongoing crises and the potential for humanity’s resilience or failure.
