90cm sea level rise "locked in" - NASA

NASA now says that a 3 foot (91cm) rise in sea levels is locked in. Might as well round that off to a metre I reckon.
"Given what we know now about how the ocean expands as it warms and how ice sheets and glaciers are adding water to the seas, it’s pretty certain we are locked into at least 3 feet of sea level rise, and probably more," said Steve Nerem of the University of Colorado, Boulder, and lead of NASA's interdisciplinary Sea Level Change Team. "But we don't know whether it will happen within a century or somewhat longer." 

The Greenland ice sheet has contributed more greatly to sea level rise, losing an average of 303 gigatons of ice a year over the past decade, while the Antarctic ice sheet has lost an average of 118 gigatons a year. But scientists at NASA and the University of California, Irvine warned last year that glaciers in the West Antarctic "have passed the point of no return." more
