'The risk from nuclear weapons is not that someone is going to press the button, but the existence of these weapons costs a lot of time, effort and money to keep them secure,' Squassoni said, adding that there have been troubling safety discrepancies reported in recent years at power plants.

(That figure seems to come from a Congressional Budget Office report from December 2013.) She said the United States has good rhetoric on nuclear nonproliferation, but at the same time is in the midst of a $335 billion overhaul of its nuclear program. Russia is upgrading its nuclear program, India plans to expand its nuclear submarine fleet, and Pakistan has reportedly started operating a third plutonium reactor, Squassoni said.

'We move the clock hand today to inspire action.'įor instance, if nothing is done to reduce the amount of heat-trapping gasses, such as carbon dioxide, in the atmosphere, Earth could be 5 to 15 degrees Fahrenheit (3 to 8 degrees Celsius) warmer by the end of century, said Sivan Kartha, a senior scientist at the Stockholm Environment Institute.

'We are not saying it is too late to take action but the window for action is closing rapidly,' Kennette Benedict, executive director of The Bulletin of the Atomic Scientists, said in a news conference this morning in Washington, D.C. Each year, the magazine's board analyzes threats to humanity's survival to decide where the Doomsday Clock's hands should be set.Įxperts on the board said they felt a sense of urgency this year because of the world's ongoing addiction to fossil fuels, procrastination with enacting laws to cut greenhouse gas emissions and slow efforts to get rid of nuclear weapons. Rather, the clock is a visual metaphor to warn the public about how close the world is to a potentially civilization-ending catastrophe. The Bulletin of the Atomic Scientists doesn't use the clock to make any real doomsday predictions.
