据报道，全球平均海平面（GMSL）由于2010/2011年的拉尼娜现象下降了5毫米，并在1年内恢复。随着观测时间的延长，到2012年底，GMSL进一步上升到11.6 mm的总量，不包括3.0 mm/年的背景趋势。根据Argo项目，高度计和重力卫星的观测结果，一个调和的海平面预算显示，真正的GMSL上升被厄尔尼诺-南方涛动相关的波动所掩盖，自2010年以来，其速度有所增加。在提取了陆地蓄水量的影响后，研究结果表明，由于陆地冰损失率和空间位阻变化率的增加，全球平均海平面以4.4 ± 0.5mm/a的速度上升了3年多。
The global mean sea level (GMSL) was reported to have dropped 5 mm due to the 2010/2011 La Niña and have recovered in 1 year. With longer observations, it is shown that the GMSL went further up to a total amount of 11.6 mm by the end of 2012, excluding the 3.0 mm/yr background trend. A reconciled sea level budget, based on observations by Argo project, altimeter, and gravity satellites, reveals that the true GMSL rise has been masked by El Niño–Southern Oscillation‐related fluctuations and its rate has increased since 2010. After extracting the influence of land water storage, it is shown that the GMSL has been rising at a rate of 4.4 ± 0.5 mm/yr for more than 3 years, due to an increase in the rate of both land ice loss and steric change.
