'Doomsday Clock' moves 90 seconds to midnight amid Ukraine crisis

The world is perilously closer to catastrophe than it has ever been as nuclear weapon use, climate change, and future risk of pandemics pose a threat

With Russia’s invasion of Ukraine and the specter of nuclear weapon use, Earth crept its closest to Armageddon, a science-oriented advocacy group said, moving its famous “Doomsday Clock” up to just 90 seconds before midnight.

“We are really closer to that doomsday,” former Mongolian President Elbegdorj Tsakhia said on January 24 at the Bulletin of Atomic Scientists’ annual announcement rating how close humanity is from doing itself in. He and former Ireland President Mary Robinson joined scientists to underscore what they consider a gathering of several existential threats, with Russian leader Vladimir Putin’s actions and words chief among them.

“People and scientists are warning us and we have to wake up now,” he said.

The advocacy group started in 1947 to use a clock to symbolise the potential and likelihood of people doing something to end humanity. It moved the clock 10 seconds closer than last year, making it the closest it has ever been to striking 12. It's been as much as 17 minutes from midnight after the end of the Cold War but in the past few years, the group has changed from counting down the minutes to midnight to counting down the seconds.

Doomsday has not happened yet.
