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.
