4 Times the World Came Close to ‘Doomsday’

At various points in post-WWII history, a distinguished group of scientists has determined how close the world is to global catastrophe. On Tuesday, the Bulletin of the Atomic Scientistsannounced the world’s Doomsday Clock would remain at 3 minutes to midnight, where it was moved in 2015.

“That decision is not good news,” the Bulletin says, “but an expression of dismay that world leaders continue to fail to focus their efforts and the world’s attention on reducing the extreme danger posed by nuclear weapons and climate change.”
