It has since been set backward eight times and forward 16 times for a total of 24, the farthest from midnight being 17 minutes in 1991, and the nearest being 100 seconds, from 2020 to the present. The clock's original setting in 1947 was seven minutes to midnight. The Bulletin 's Science and Security Board monitors new developments in the life sciences and technology that could inflict irrevocable harm to humanity. The main factors influencing the clock are nuclear risk and climate change. A hypothetical global catastrophe is represented by midnight on the clock, with the Bulletin 's opinion on how close the world is to one represented by a certain number of minutes or seconds to midnight, assessed in January of each year. Maintained since 1947, the clock is a metaphor for threats to humanity from unchecked scientific and technological advances. The Doomsday Clock is a symbol that represents the likelihood of a man-made global catastrophe, in the opinion of the members of the Bulletin of the Atomic Scientists.
