Mysterious CO2: Not dangerous enough to prevent the "Doomsday Clock" from moving from 11:55 to 11:54 two years ago, but dangerous enough to help move it back to 11:55 from 11:54 now

Doomsday Clock Moves 1 Minute Closer to Midnight -- WASHINGTON, Jan. 10, 2012

WASHINGTON, Jan. 10, 2012 /PRNewswire-USNewswire/ -- Faced with inadequate progress on nuclear weapons reduction and proliferation, and continuing inaction on climate change, the Bulletin of the Atomic Scientists (BAS) announced today that it has moved the hands of its famous "Doomsday Clock" to five minutes to midnight.

The last time the Doomsday Clock minute hand moved was in January 2010, when the Clock's minute hand was pushed back one minute from five to six minutes before midnight.
