The world has nudged closer to a nuclear apocalypse and environmental disaster, a trans-Atlantic group of prominent scientists warned Wednesday, pushing the hand of its symbolic Doomsday Clock two minutes closer to midnight.
It was the fourth time since the end of the Cold War that the clock has ticked forward, this time from 11:53 to 11:55, amid fears over what the scientists are describing as "a second nuclear age" prompted largely by atomic standoffs with Iran and North Korea.
But the organization added that the "dangers posed by climate change are nearly as dire as those posed by nuclear weapons."
The Chicago-based Bulletin of the Atomic Scientists, founded in 1945 as a newsletter distributed among nuclear physicists concerned by the possibility of nuclear war, has since grown into an organization focused more generally on manmade threats to the survival of human civilization. "As scientists, we understand the dangers of nuclear weapons and their devastating effects, and we are learning how human activities and technologies are affecting climate systems in ways that may forever change life on Earth," said Stephen Hawking, the renowned cosmologist and mathematician.
"As citizens of the world, we have a duty to alert the public to the unnecessary risks that we live with every day, and to the perils we foresee if governments and societies do not take action now to render nuclear weapons obsolete and to prevent further climate change."
The bulletin's clock, which for 60 years has followed the rise and fall of nuclear tensions, would now also measure climate change, the bulletin's editor Mark Strauss told The Associated Press.
It came closest to midnight -- just two minutes away -- in 1953, following the successful test of a hydrogen bomb by the United States. It has been as far away as 17 minutes, set there in 1991 following the demise of the Soviet Union.
