Countdown to catastrophe: Doomsday Clock moved closer to midnight
Rising threats from climate change and nuclear arsenals prompted the scientists who maintain the Doomsday Clock, a symbolic countdown to global catastrophe, to move it two minutes closer to midnight on Thursday, its first shift in three years.
The Doomsday Clock, devised by the Chicago-based Bulletin of the Atomic Scientists, now stands at three minutes to midnight, or doomsday.
It was last adjusted in January 2012, when it was moved one minute closer to midnight.
