Since 1900, global average sea level has risen by about 7–8 inches. It is projected to rise another 1–8 feet, with a likely range of 1–4 feet, by 2100. Sea level rise will increase the frequency, extent, and severity of coastal flooding along the Philadelphia riverfront, where the observed sea level rise over the past century has exceeded the global average.
