Earth is closer than it’s ever been to destruction as Russia, China, the U.S. and other countries become “increasingly aggressive, adversarial, and nationalistic,” a science-oriented advocacy group said Tuesday and advanced its “Doomsday Clock” to 85 seconds till midnight.

The Bulletin of the Atomic Scientists cited risks of nuclear war, climate change, potential misuse of biotechnology and the increasing use of artificial intelligence without adequate controls as it made the annual announcement, which rates how close humanity is from ending.

Last year, the clock advanced to 89 seconds to midnight.

Since then, “hard-won global understandings are collapsing, accelerating a winner-takes-all great power competition and undermining the international cooperation” needed to reduce existential risks, the group said.
