According to a new study published yesterday (April 2) in the journal Nature Geoscience, ice is receding deep below eight of Antarctica’s largest glaciers at an alarming rate — roughly five times faster than it should be. If this marine ice recession continues, it could lead to a total collapse of the world’s largest ice sheet, the study found. [Images of Melt: Earth’s Vanishing Ice]
“Our study provides clear evidence that retreat is happening across the ice sheet due to ocean melting at its base,”
