"Sea-level rise, a problem exacerbated by greenhouse gas emissions, could disrupt the lives of more than 13 million people in the United States, three times the most current estimates, according to a study published Monday.

Rising seas, which already endanger coastal communities through tidal floods and storm surges, could rise three feet or more over the next century if emissions continue at a high level, threatening many shoreline communities. The study, published in Nature Climate Change, argues that most projections vastly underestimate the number of people at risk because they do not account for population growth.

For the study, the authors combined future population estimates with predicted sea-level rise, using data from the National Oceanic and Atmospheric Administration, to demonstrate that millions are at risk: 4.2 million if seas rise by three feet, or 13.1 million with a six-foot increase, a high-end estimate."
