Study: Sea level rise to swamp US coastal cities by 2100 - Science Fair: Science and Space News - USATODAY.com

The report states that the Gulf and southern Atlantic coasts will be particularly hard hit. Miami, New Orleans, Tampa, Fla., and Virginia Beach, Va. could lose more than 10 percent of their land area by 2100 due to sea-level rise.

"With the current rate of greenhouse gas emissions, the projections are that the global average temperature will be 8 degrees warmer than present by 2100," says lead researcher Jeremy L. Weiss, a senior research specialist in the University of Arizona's department of geosciences.

"That amount of warming will likely lock us into at least 4 to 6 meters of sea-level rise in subsequent centuries, because parts of the Greenland and Antarctic ice sheets will slowly melt away like a block of ice on the sidewalk in the summertime," Weiss says.
