Doomsday Clock moves closer to midnight
The Doomsday Clock, a symbolic gauge of nuclear danger, has moved one minute closer to midnight because of "inadequate progress" on nuclear and climate issues.
The Bulletin of the Atomic Scientists (BAS) announced the move - to five minutes before midnight - on Tuesday.
The clock last moved one minute, back in 2010.
Allison Macfarlan and Lawrence Krauss of the Bulleting of Atomic Scientists said proliferation is increasing rather than decreasing.
