A new government report says sea levels on the U.S. coast line are expected to rise by at least 0.25 meters in the next 30 years.
一份新的政府报告称，美国海岸线的海平面预计在未来30年将上升至少0.25米。
The National Oceanic and Atmospheric Administration and six other federal agencies created the report.
美国国家海洋和大气管理局和其他六个联邦机构撰写了这份报告。
It predicts that the sea level along the U.S. coast will be 0.25 to 0.3 meters higher by 2050.
它预测，到2050年，美国海岸线的海平面将上升0.25至0.3米。
The report warns of more floods from storms and high water levels on the coast even on sunny days during high tides.
该报告警告称，即使是在晴天的涨潮期间，海岸上的暴风雨和高水位也会造成更多的洪水。
"Make no mistake: Sea level rise is upon us," said Nicole LeBoeuf, director of NOAA's National Ocean Service.
美国国家海洋和大气管理局国家海洋局局长妮可·勒博夫说：“毫无疑问：海平面上升正在逼近我们。”
LeBoeuf warned that the cost will be high.
勒博夫警告说，代价将会很高。
She said the United States coasts are home to a lot of economic activity and 40 percent of the U.S. population.
她说，美国沿海地区有许多经济活动，人口占美国总人口的40%。
William Sweet was the report's lead writer.
威廉·斯威特是这份报告的主要作者。
He said that the largest sea level rise from melting of ice in Antarctica and Greenland probably will not start until after 2100.
他说，南极洲和格陵兰岛冰川融化导致的最大幅度的海平面上升可能到2100年以后会开始。
Sea levels can rise more in some places than others because land can sink.
因为陆地可能会下沉，一些地方的海平面可能会比其他地方上升得更多。
Also, currents and water from melting ice are different from place to place.
此外，冰川融化产生的水和水流也因地而异。
The report predicts sea levels in the U.S. will rise more than the world average.
该报告预测，美国海平面的上升幅度将会超过世界平均水平。
Sweet said the greatest rise in the U.S. will be on the Gulf of Mexico and East Coast.
斯威特说，美国海平面上升幅度最大的将是墨西哥湾和东海岸。
The West Coast and Hawaii will be below the average.
西海岸和夏威夷将低于平均水平。
The report predicts 0.6 meters of sea level rise in St. Petersburg, Florida, a city on the Gulf of Mexico.
该报告预测，墨西哥湾沿岸的佛罗里达州圣彼得堡市的海平面将上升0.6米。
But the study predicts just 0.36 meters in Los Angeles, California.
但这项研究预测加州洛杉矶的海平面只上升0.36米。
Cities like Miami Beach, Florida; Annapolis, Maryland; and Norfolk, Virginia already get a few minor floods every year during high tides.
佛罗里达州的迈阿密海滩、马里兰州的安纳波利斯和弗吉尼亚州的诺福克等城市在每年的涨潮期间都会发生几次轻微的洪水。
The researchers said those will be replaced by several "moderate" floods by about 2050.
研究人员表示，到2050年左右，这些洪水将被几次“中度”洪水取代。
Those floods will cause property damage.
那些洪水将会造成财产损失。
"It's going to be areas that haven't been flooding that are starting to flood," Sweet said.
斯威特说：“没有发生过洪灾的地区将开始发生洪灾。”
He added, "Many of our major metropolitan areas on the East Coast are going to be increasingly at risk."
他还说，“我们东海岸的许多主要大都市都将面临越来越大的风险。”
The report said the western coast of the Gulf of Mexico should have the biggest sea level rise by 2050.
该报告称，到2050年，墨西哥湾西海岸的海平面的上升幅度应该是最大的。
The researchers predict a sea level rise of 0.4 to 0.45 meters.
研究人员预测海平面将上升0.4到0.45米。
The eastern Gulf of Mexico should expect 0.35 to 0.4 meters of sea level rise by 2050.
到2050年，墨西哥湾东部的海平面预计将上升0.35至0.4米。
The Southeast U.S. coast should get 0.3 to 0.35 meters of sea level rise.
美国东南海岸的海平面应该会上升0.3到0.35米。
And the Northeast U.S. coast should get 0.25 to 0.3 meters of sea level rise.
而美国东北海岸的海平面应该会上升0.25到0.3米。
The report is estimating an average of about 0.6 meters of sea level rise in the United States as a whole by 2100.
该报告估计，到2100年，美国整体海平面平均上升约0.6米。
