In January 2018, the Bulletin of the Atomic Scientists (BAS) moved its Doomsday Clock closer to midnight: it now reads 11:58. The last time the minute hand was this close to the hour of Armageddon was 1953, just after the United States and Soviet Union tested thermonuclear bombs. Since then the stylized clock has ticked backward and forward, each year metaphorically registering civilization's proximity to global catastrophe. “To call the world's nuclear situation dire,” the group warned in its January statement, “is to understate the danger—and its immediacy.”
