|a 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 share Hay’s concerns, says geologist Harold Wanless
of the University of Miami. “The rate at which ice melt and sea level rise
is happening is far faster than anything predicted,” he says.
Global sea levels rose an average of about 15 centimeters over the
past century. Current data suggest they will rise another 1 meter by the
year 2100, and some scientists predict far more. But the 2007 report of
the Intergovernmental Panel on Climate Change projected a rise of just
0.2–0.6 meters over the same time period. “The data weren’t available in
2007 to say Greenland and Antarctica were melting,” says earth
scientist Benjamin Horton of the University of Pennsylvania in
Philadelphia. “Sea levels are going to be greater than the upper estimate
of the 2007 IPCC, but the big question is, when?” |
