The movement of the Doomsday Clock to just 90 seconds to midnight sends a message that the world's situation is urgent, with possible broad consequences and long-standing effects, said the Bulletin's president, Rachel Bronson.

Those who are listening say 'The world doesn't feel safer today,' – they're not alone," she said.
