美國聯邦機構警告說，美國海平面從現在至2050年，將以前所未有的速度上升。
America's coastline will see sea levels rise in the next 30 years by as much as they did in the entire 20th century, with major Eastern cities hit regularly with costly floods even on sunny days, a government report warns.
美國海岸在未來30年，將看到海平面以整個20世紀的速度上升，主要是東海岸城市會經常受到損失慘重的洪水的襲擊，既是是在陽光明媚的時候，聯邦政府報告警告說。
By 2050, seas lapping against the U.S. shore will be 10 to 12 inches (0.25 to 0.3 meters) higher, with parts of Louisiana and Texas projected to see waters a foot and a half (0.45 meters) higher, according to a 111-page report issued Tuesday by the National Oceanic and Atmospheric Administration and six other federal agencies.
根據國家海洋和氣候管理局與六個其他聯邦政府機構週二聯合釋出的111頁的報告，到2050年，海水將淹沒美國海岸0.25到0.3米高度，路易斯安那和德克薩斯州的部分地區將見證0.45米的海水上漲。
