The causes of contemporary sea level rise over recent two decades: progress and challenge
Revealing the cause of global mean sea level (GMSL) rise helps to advance the knowledge of current climate change, and make adaptive planning. Space geodesy technique along with Argo float greatly improves the investigation of the cause of sea level rise on global and regional scales. These observat...

Revealing the cause of global mean sea level (GMSL) rise helps to advance the knowledge of current climate change, and make adaptive planning. Space geodesy technique along with Argo float greatly improves the investigation of the cause of sea level rise on global and regional scales. These observations serve as important supplements to model output that usually fail to capture long-term trend, in addition to providing independent verifications, they also help to understand the drivers of sea level change on long-term and interannual scales. This paper reviews the achievements and progresses in the cause of sea level change, with a particular focus on discussing the contributions of mass variations over global land area. Observations suggests that, over recent two decades, 65% GMSL rise is caused by ocean mass increase due to mass loss in polar ice sheet and mountain glacier, and land hydrology.
