The Doomsday Clock is a symbolic clock face, maintained since 1947 by the board of directors of the Bulletin of the Atomic Scientists. The closer the clock is to midnight, the closer the world is estimated to be to global disaster. Originally, the Clock, which hangs on a wall in the Bulletin's office in the University of Chicago, represented an analogy for the threat of global nuclear war; however, since 2007 it has also reflected climate change. The most recent officially announced setting—three minutes to midnight (11:57)—was made in January 2015 due to "[un]checked climate change, global nuclear weapons modernizations, and outsized nuclear weapons arsenals". This setting was retained in January 2016.
