Submission + - Antarctic ice sheet melt accelerating 1
OriginalArlen writes: The rapidly diminishing extent of Arctic sea-ice has been widely covered here and elsewhere. Now NASA scientists using satellite data have published a paper in 'Science' demonstrating increased melting around the margins (mostly) of the Antarctic ice sheet. This is potentially much more serious, as the margins act as barriers, preventing the much larger land-borne ice-sheets sliding off the continent into the sea — causing a catastrophic 4-6m rise in sea-levels.
