Doomsday Clock at record 90 seconds to midnight amid Ukraine crisis

Scientists warn of ‘unprecedented danger’ and say ‘Russia’s war … has raised profound questions’

The Bulletin of the Atomic Scientists set its Doomsday Clock at 90 seconds to midnight, the closest to midnight the clock has been since it was established in 1947 to illustrate global existential threats at the dawn of the nuclear weapons age.
