Global sea levels have risen through the 20th century. These rises will almost certainly accelerate through the 21st century and beyond because of global warming, but their magnitude remains uncertain. Key uncertainties include the possible role of the Greenland and West Antarctic ice sheets and the amplitude of regional changes in sea level. In many areas, nonclimatic components of relative sea-level change (mainly subsidence) can also be locally appreciable. Although the impacts of sea-level rise are potentially large, the application and success of adaptation are large uncertainties that require more assessment and consideration.
全球海平面在 20 世纪上升。由于全球变暖，这些上升在 21 世纪及以后几乎肯定会加速，但它们的幅度仍不确定。主要的不确定性包括格陵兰和西南极冰盖的可能作用以及海平面区域变化的幅度。在许多地区，海平面变化的非气候组成部分（主要是沉降）也可能在当地显著。尽管海平面上升的影响可能很大，但适应措施的应用和成功存在很大的不确定性，需要更多的评估和考虑。
