The Doomsday Clock is a device maintained by the Bulletin of the Atomic Scientists at the University of Chicago which is used to indicate the threat of a nuclear, biological, or environmental disaster. It is a clock face, where midnight represents a nuclear war, and noon represents world peace. It has been "operational" since 1947. The lowest time it reached was 11:43, shortly after the fall of the Soviet Union. It was closest to midnight during 1953, after the US and the USSR tested their thermonuclear weapons, where it read 11:58. 
The clock currently reads 11:55, to which it was set at 10 January 2012 due to "inadequate progress on nuclear weapons reduction and proliferation, and continuing inaction on climate change".
