Global threats move ‘Doomsday Clock’ closer to midnight

Rising tension between Russia and the U.S., North Korea’s recent nuclear test and a lack of aggressive steps to address climate change are putting the world under grave threat, scientists behind a “Doomsday Clock” that measures the likelihood of a global cataclysm said Tuesday.
The Bulletin of the Atomic Scientists announced that the minute hand on the metaphorical clock remained at three minutes-to-midnight. The clock reflects how vulnerable the world is to catastrophe from nuclear weapons, climate change and new technologies, with midnight symbolizing apocalypse.
