This article discusses the impact on US coastal cities because of sea level rising.
Major coastal cities—from New York and Boston to San Francisco and smaller communities like Imperial Beach, Calif.—are already preparing for a potentially perilous future because of sea level rise.
But even though these cities have spent years assessing their risks, and found price tags that run into the billions to adapt, new studies of Antarctic ice loss and coastal real estate risk suggest they may be far underestimating the costs that lie ahead.
A recent study published in the journal Nature found that the rate of Antarctic ice loss has tripled in the past five years. That means sea level rise could sink more than 300,000 U.S. coastal residential and commercial properties (worth approximately $117.5 billion) by 2045, according to an analysis also published recently by the Union of Concerned Scientists.
