The Doomsday Clock, which symbolically measures the end of time, marked yesterday that humanity has never been so close to a planetary cataclysm due to the Russian incursion into Ukraine, nuclear tensions and the climate crisis. The Bulletin of Atomic Scientists, whose science and safety board includes 11 Nobel laureates, describes the clock as a “metaphor for how close the world is to self-annihilation.” He moved the 100 to 90 second hands to midnight.
