About one-quarter of the world's population lives in coastal areas that will be unlivable by the year 2100 because of rising sea levels, researchers say. In a special issue of the journal Earth's Future, coastal scientists and engineers detailed projections for sea-level rise for the year 2100, and described their model Monday (Dec. 12) here at the annual meeting of the American Geophysical Union. "To really understand how this might be impacted by sea-level rise, or other kinds of change, we need to understand all of the different scales and how they interact," Nicholls said.
