The Bulletin of the Atomic Scientists on Monday said its famous Doomsday Clock would stay at five minutes to midnight, indicating the world is not moving significantly closer or farther away from annihilation.
The publication's Science and Security Board issued an open letter to President Obama addressing nuclear weapons, fissile materials, climate change and developing dangers.
"2012 was a year of unrealized opportunity to reduce nuclear stockpiles, to lower the immediacy of destruction from missiles on alert, and to control the spread of fissile materials and keep nuclear terrorism at bay," the letter states. "2012 was a year in which -- one year after the partial meltdown at the Fukushima Daiichi Nuclear Power Station -- the Japanese nation continued to be at the earliest stages of what will be a costly and long recovery. The stasis of 2012 convinces us, the Science and Security Board, to keep the hands of the Doomsday Clock in place."
It offered several recommendations for Obama's second term in office, including pledging to reduce the fielded U.S. strategic nuclear arsenal to fewer than 1,000 warheads and pressing for the end to manufacturing of nuclear weapon-usable fissile material and eliminating present stocks of the materials.
