Doomsday Clock moves to 90 seconds to midnight due to ‘mounting dangers’ of war in Ukraine

The Bulletin of the Atomic Scientists on Tuesday moved the hands of the Doomsday Clock to 90 seconds to midnight. "Largely, though not exclusively, because of the mounting dangers of the war in Ukraine, we move the clock forward, the closest it has ever been to midnight," said Rachel Bronson, the president and CEO of the Bulletin.
