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.
