Sea level rise overflowing estimates
Feedback mechanisms are speeding up ice melt

Sea levels may swell much higher than previously predicted, thanks to feedback mechanisms that are speeding up ice melt in Greenland and Antarctica.
Climate simulations need to take such feedbacks into account, William Hay, a geologist at the University of Colorado Boulder, told the Geological Society of America meeting in Charlotte, N.C., on November 4. So far the models haven’t incorporated such information because “it just makes them much more complicated,” he says.
Many scientists sha...
