Anywhere from 4.3 to 13.1 million people in the coastal United States will be at risk of inundation due to sea level rise by 2100, according to a new study that combines population growth projections with sea level rise forecasts.
The study, published in Nature Climate Change, uses population trends and sea level rise projections to conduct a county-by-county risk assessment across the U.S. The results show that anywhere from 4.3 to 13.1 million people are at risk of inundation by 2100, depending on how much sea level rise there is by then.
