去年中国沿海海平面较常年高84毫米

China has recorded a high coastal sea level over the past 10 years, reaching a peak in 2021 according to a report by the Ministry of Natural Resources.

自然资源部近日发布的《2021年中国海平面公报》显示，过去10年（2012年~2021年）我国沿海海平面总体呈波动上升趋势，并于2021年达到高位。

Over the past year the sea level has been 84 millimeters higher than it was between 1993 and 2011.
2021年，我国沿海海平面较常年(公报将1993-2011年定为常年时段)高84毫米。

The rising sea level is largely due to global warming, which has led to the expansion of seawater and the melting of glaciers and polar ice caps.
全球海平面上升主要由气候变暖导致的海水增温膨胀、陆地冰川和极地冰盖融化等因素造成。

In China, land subsidence also contributes to a relative rise in sea level.
此外，在我国，地面沉降也会造成局地海平面相对上升。
