ScienceDaily (Mar. 14, 2012) — Nearly four million Americans, occupying a combined area larger than the state of Maryland, find themselves at risk of severe flooding as sea levels rise in the coming century, new research suggests.
Two ways in which global warming is causing sea levels to rise are thermal expansion – the expanding of water as it warms – and the melting of glaciers.
Co-author of both papers, Ben Strauss, researcher at Climate Central, said: "The sea level rise taking place right now is quickly making extreme coastal floods more common, increasing risk for millions of people where they live and work. Sea level rise makes every single coastal storm flood higher. With so many communities concentrated on US coasts, the odds for major damage get bigger every year."
