A special clock tells a story.
It shows how safe our world is. Scientists use this clock to show danger. Midnight means a big problem could happen.
Many things can move the clock. Big wars or changes in our air can move it. New tools like smart machines also matter.
The clock started a long time ago. It began at seven minutes to midnight.
Sometimes the clock moves far from midnight. This means things are better. Other times it moves very close to midnight.
We can take action to help. This can keep our world safe. People work hard to change the time.
The Doomsday Clock is a special symbol. It shows how close our world is to a big disaster. A group called the Bulletin of the Atomic Scientists manages it. They check the time every January.
Midnight on the clock means a global catastrophe could happen. This is a very bad event for all people. Scientists look at many things to set the time. They study nuclear weapons and climate change. They also look at new tools like artificial intelligence.
The clock started in 1947. Its first setting was seven minutes to midnight. Since then, the time has changed many times. Sometimes the clock moves far from midnight. This happens when the world feels safer. In 1991, it was 17 minutes away.
Other times, the clock moves very close to midnight. In 2026, it was set to 85 seconds to midnight. This is the closest it has ever been. Scientists say this is due to a failure of leadership. They want people to take action to keep us safe.
The Doomsday Clock is a famous symbol used to show how close our world is to a global catastrophe. A catastrophe is a huge disaster that could harm all people. This symbol is managed by a group called the Bulletin of the Atomic Scientists. They use the clock to show the danger from new science and technology. Midnight on the clock represents the end of civilization. The time shown tells us how many minutes or seconds we have left.
Setting the clock is a careful job done every January. A Science and Security Board looks at many different things. They study nuclear weapons and how countries use them. They also look at climate change and how our planet is warming. Other big concerns include artificial intelligence and biological threats. They even look at how people use information to spread lies. The board meets to decide how close we are to midnight.
The history of the clock began in 1947. It was created by researchers who worked on the Manhattan Project. These scientists wanted to warn people about the dangers of atomic energy. A woman named Martyl Langsdorf designed the very first clock cover. She chose a clock because it works like a countdown. This suggests that destruction might happen unless people take action to stop it. Since then, the Bulletin has moved the clock 27 times.
The clock has moved back and forth many times since it started. In 1947, the first setting was seven minutes to midnight. In 1991, the clock was set far away at 17 minutes. However, some years have been much more dangerous. In 1953, it was only two minutes to midnight. In 2017, the time was 150 seconds. By 2026, the clock reached its closest point of 85 seconds.
Many people around the world recognize this clock as a metaphor. A metaphor is a way to describe a big idea using a symbol. Some people criticize the clock and say it is not always fair. They argue that it might make people feel too scared to act. Others think the scientists should use more exact math to set the time. Despite this, the clock remains a powerful way to talk about our future. It reminds us that leaders and citizens must work together to stay safe.
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.
