The report found that global sea levels have risen about 8 inches since 1880 and are projected to rise 1 to 4 feet by 2100. The impact to 140,000 acres of coastline in Oregon and Washington that lie within 3.3 feet of the high tide line would mean a higher frequency of flooding during storm surges.
