The Bulletin of the Atomic Scientists moved its Doomsday Clock one minute closer to midnight. The clock, which now stands at five minutes until midnight, was changed due to concerns over the threats ofexpanded nuclear power and grave environmental dangers due to climate change.  The clock, created in 1947, has shifted numerous times since its creation, most recently in 2010. The clock and the phrase “minutes to midnight” are symbolism for how close the Bulletin of the Atomic Scientists believes the world is to “Doomsday.”
