The "Doomsday" glacier has begun moving (3 photos)

Scientists report that Antarctica's "Doomsday Glacier" has begun to shift.

An international team is conducting research on the Thwaites Glacier, which is feared to be rapidly melting: its melting could lead to a rise in global sea levels of 60 centimeters or, in the worst case, 3-5 meters. Satellites have recorded warm waters eroding its base and the appearance of new cracks.
