The worst potential scenario for sea level rise around the US coastline this century is more than two meters, says an authoritative report issued today by NOAA’s Climate Program Office. Regardless of how much warming occurs over the next 100 years, sea level rise is not expected to stop in 2100. More than 8 million people in the US live in areas at risk of coastal flooding. Along the Atlantic Coast alone, almost 60 percent of the land that is within a meter of sea level is planned for further development, with inadequate information on the potential rates and amount of sea level rise.
