Doomsday Clock Moves to 85 Seconds, Urging Global Action

Scientists have adjusted the Doomsday Clock to a precarious position of 85 seconds to midnight, marking the closest humanity has ever been to global catastrophe. This decision was announced on January 24, 2026, by the Bulletin of the Atomic Scientists, an organization founded in 1945 by experts who contributed to the Manhattan Project. The clock serves as a symbolic gauge of how close humanity is to self-destruction, with midnight representing a point of no return for Earth’s habitability.

The clock was previously set at 89 seconds to midnight in 2025 and had briefly reached 90 seconds in 2023 and 2024. The recent move reflects a concerning lack of progress in addressing critical global issues such as nuclear risk, climate change, biological threats, and the rapid advancements in disruptive technologies, notably artificial intelligence. According to Bulletin President and CEO Alexandra Bell, “Humanity has not made sufficient progress on the existential risks that endanger us all.” She emphasized that every second counts and urged immediate action.

Historical Context and Purpose of the Doomsday Clock

The Bulletin of the Atomic Scientists established this clock in 1947 as a means to highlight the dangers posed by nuclear weapons. Over the decades, its scope has expanded to include climate change and other technological threats. The decision on the clock’s time is made by experts from the Bulletin’s science and security board, which includes eight Nobel laureates. This board consults with the Bulletin’s board of sponsors, which was formed by notable figures such as Albert Einstein and J. Robert Oppenheimer.

Each year, the time is adjusted based on the perceived level of risk to humanity. Some experts argue that while the clock is an important rhetorical device, it may not perfectly capture the complexities of various threats. For instance, Dr. Michael Mann, a distinguished professor at the University of Pennsylvania, described the clock as an “imperfect metaphor.” He noted that it combines different types of risks that occur over varying timescales. Nonetheless, he acknowledged its significance in raising awareness about the fragility of human existence.

Implications of the Clock’s Time and What Lies Ahead

The Doomsday Clock has never reached midnight, a point that would signify catastrophic events such as nuclear warfare or irreversible climate change. Former Bulletin President and CEO Rachel Bronson expressed a hope that humanity will never face this dire situation. She stated, “When the clock is at midnight, that means there’s been some sort of nuclear exchange or catastrophic climate change that’s wiped out humanity.”

Despite the grim assessment, there remains an opportunity to move the clock back. The furthest the clock has been from midnight was 17 minutes in 1991, following the signing of the Strategic Arms Reduction Treaty by then-President George H.W. Bush and the Soviet Union. Bronson reaffirmed that since humans created these existential threats, they have the capacity to mitigate them. Achieving this requires serious global engagement and substantial actions at all societal levels.

Every individual can contribute to reversing the clock’s ominous tick. Simple lifestyle changes, such as opting for public transport over driving or reducing energy consumption, can make a significant impact. Public discourse around these issues is equally vital, as it can encourage leaders to take decisive action.

In a world increasingly fraught with challenges, the Doomsday Clock serves as a stark reminder of the urgent need for collaborative efforts to secure a sustainable future. As the clock ticks down, the message is clear: bold action is essential to steer humanity away from the brink of disaster.
