Lasrick writes "The Doomsday Clock remains at 5 minutes to midnight. In a letter to United Nations Secretary-General Ban Ki-Moon and members of the UN Security Council, the Bulletin announced its decision and how it was made. The decision to move (or to leave in place) the minute hand of the Doomsday Clock is made every year by the Bulletin's Science and Security Board in consultation with its Board of Sponsors, which includes 18 Nobel laureates. The Clock has become a universally recognized indicator of the world's vulnerability to catastrophe from nuclear weapons, climate change, and new technologies emerging in other domains." Reasons for the clock remaining at five minutes include the U.S. and Russian not doing much for disarmament increasing nuclear weapon stockpiles in India and China, stalled efforts to reduce carbon emissions globally, and "killer robots."
