报告：未来30年美国海平面将大幅上升

Sea levels along US coastlines will rise between 25 to 30 centimeters on average, above the current levels by 2050, according to a new interagency report published on Tuesday.

2月15日新公布的一份机构间报告称，到2050年，美国海岸线周围的海平面将平均上升25到30厘米。

Coastal flooding will increase significantly over the next 30 years because of the rise, according to the report by an interagency sea level rise task force that includes NASA, the National Oceanic and Atmospheric Administration, and other federal agencies. The report projects that the rise in ocean height in the next 30 years could equal the total rise seen over the past 100 years.
包括美国宇航局、美国国家海洋和大气管理局和其他联邦机构在内的一个机构间海平面上升工作组预计，美国未来30年海平面将大幅升高，上升幅度或与过去100年的升幅相当。由于海平面上升，未来30年沿海洪水将显著增加。
