Doomsday Clock

The Doomsday Clock is a symbolic representation created by the Bulletin of the Atomic Scientists to illustrate the perceived threat of global catastrophe, particularly from nuclear weapons, climate change, and emerging technologies. The clock's hands are moved closer to midnight to indicate increasing danger and further away to suggest a decrease in threat levels. Midnight represents the hypothetical point of global disaster. Since its inception in 1947, the Doomsday Clock has been adjusted multiple times based on global events and perceived risks.
