Doomsday Clock Moves: 5 minutes to midnight..

North Korea’s recent test of a nuclear weapon, Iran’s nuclear ambitions, a renewed U.S. emphasis on the military utility of nuclear weapons, the failure to adequately secure nuclear materials, and the continued presence of some 26,000 nuclear weapons in the United States and Russia are symptomatic of a larger failure to solve the problems posed by the most destructive technology on Earth.

As in past deliberations, we have examined other human-made threats to civilization. We have concluded that the dangers posed by climate change are nearly as dire as those posed by nuclear weapons. The effects may be less dramatic in the short term than the destruction that could be wrought by nuclear explosions, but over the next three to four decades climate change could cause drastic harm to the habitats upon which human societies depend for survival.

This deteriorating state of global affairs leads the Board of Directors of the Bulletin of the Atomic Scientists--in consultation with a Board of Sponsors that includes 18 Nobel laureates--to move the minute hand of the “Doomsday Clock” from seven to five minutes to midnight.

Nuclear weapons present the most grave challenge to humanity, enabling genocide with the press of a button. In 1945, scientists warned the world about the nearly unimaginable destructive power of the atomic bombs they had created.

As Eugene Rabinowitch, one of the cofounders of the Bulletin, wrote, “The Bulletin’s Clock is not a gauge to register the ups and downs of the international power struggle; it is intended to reflect basic changes in the level of continuous danger in which mankind lives in the nuclear age, and will continue living, until society adjusts its basic attitudes and institutions.”
