The Doomsday Clock is a symbolic representation of the likelihood of a human-made global catastrophe. It is maintained by the Bulletin of the Atomic Scientists, a nonprofit organization. In this system, midnight represents a hypothetical global catastrophe or the end of civilization. The time shown on the clock serves as a proxy for the threats facing humanity. This includes dangers arising from unchecked scientific and technological advances. The Bulletin assesses these risks every January to determine the setting.

The mechanism for setting the clock involves a detailed review by the Bulletin's Science and Security Board. This board monitors developments in the life sciences and technology. They look for factors that could inflict irrevocable harm on humanity. The primary factors influencing the clock include nuclear warfare, climate change, and artificial intelligence. They also consider politics, energy, weapons, diplomacy, and climate science. Members of the board discuss how close they believe humanity is to a global disaster. This process helps them decide if the clock should move closer to or further from midnight.

The clock has moved through many distinct stages of danger since its creation. It was first established in 1947 with a setting of seven minutes to midnight. Since then, the clock has been adjusted a total of 27 times. It has been set backward eight times and moved forward 19 times. The furthest the clock has ever been from midnight was 17 minutes in 1991. Conversely, the closest it has ever been is 85 seconds in 2026. Recent years have seen the clock move very close to midnight in small increments.

The history of the clock traces back to the Chicago Atomic Scientists. This was an international group of researchers who had participated in the Manhattan Project. Following the atomic bombings of Hiroshima and Nagasaki, they began publishing a newsletter. This later became the Bulletin of the Atomic Scientists magazine. In 1947, co-founder Hyman Goldsmith asked artist Martyl Langsdorf to design a cover. Langsdorf chose the clock to reflect a sense of urgency. The clock acts like a countdown to suggest that destruction could occur without human action.

Specific historical events have driven the clock's movements for decades. In 1949, the clock moved to three minutes after the Soviet Union tested its first atomic bomb. In 1953, it reached a low point of two minutes during hydrogen bomb testing. The clock moved further away in 1963 to twelve minutes after the Partial Test Ban Treaty was signed. More recently, the clock has moved closer due to modern tensions. In 2023, it was set to 90 seconds because of the Russian invasion of Ukraine. In 2025, it moved to 89 seconds due to concerns over artificial intelligence.

The significance of the clock is seen in how it attracts global attention. The Bulletin reports that the clock attracts more daily visitors to its website than any other feature. It has become a universally recognized metaphor for global risk. However, the clock also faces various forms of criticism from experts. Some, like Anders Sandberg, suggest the mix of threats might cause paralysis. Others, such as cognitive psychologist Steven Pinker, have called it a political stunt. Critics like James Ball have questioned the lack of an objective methodology for the settings.

Beyond simple warnings, the clock connects to broader discussions about leadership and science. The Bulletin calls for action from wise public officials and citizens to steer humanity away from disaster. Scientist Lawrence Krauss has noted that leaders must make decisions based on facts to preserve the future. The clock links scientific data to political reality and social responsibility. It serves as a tool to communicate the gravity of complex issues like disinformation and biological threats. Ultimately, the clock remains a way to prompt human intervention in the face of technological risk.
