Scientist Stephen Hawking described climate change Wednesday as a greater threat to the planet than terrorism. Hawking made the remarks as other prominent scientists prepared to push the giant hand of its Doomsday Clock _ a symbol of the risk of atomic cataclysm and now also of climate change _ closer to midnight. Hawking warned that "as citizens of the world, we have a duty to alert the public to the unnecessary risks that we live with every day."
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 trans-Atlantic group of scientists is 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 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.
"There's a realization that we are changing our climate for the worse," he said, "That would have catastrophic effects. Although the threat is not as dire as that of nuclear weapons right now, in the long term we are looking at a serious threat."
The threat of nuclear war, however, remains by far the organization's most pressing concern. "It's important to emphasize 50 of today's nuclear weapons could kill 200 million people," he said.
The decisions to move the clock is made by the bulletin's board, which is composed of prominent scientists and policy experts, in coordination with the group's sponsors.
Since it was set to seven minutes to midnight in 1947, the hand has been moved 18 times, including Wednesday's move.
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.
