Jan. 28 (UPI) -- The symbolic Doomsday Clock managed by the Bulletin of the Atomic Scientists, has been moved forward by 3 seconds this year, making it now 85 seconds to midnight.

On Tuesday, the group released its annual warning. It said that global leaders didn't heed last year's warning, moving the Earth closer to global catastrophe due to man-made causes.

"Rather than heed this warning, Russia, China, the United States, and other major countries have instead become increasingly aggressive, adversarial, and nationalistic," the Bulletin's statement said. "Hard-won global understandings are collapsing, accelerating a winner-takes-all great power competition and undermining the international cooperation critical to reducing the risks of nuclear war, climate change, the misuse of biotechnology, the potential threat of artificial intelligence, and other apocalyptic dangers."

The group of atomic scientists said world leaders have become unconcerned.
