Sea Level Change: Observation, Analysis and Attribution

Abstract

In the context of global warming, the expansion of seawater, the melting of terrestrial glacier and other factors have led to an increase in seawater quality and volume, causing global sea level rise, which is an important indicator of climate change, as well as a hot spot for climate change research. According to the IPCC Assessment Report [1,2], the sea level rise shows the transition from a relatively low average rate in the past two thousand years very likely that the global average sea level rise continues to accelerate since the early 20th century. In addition, since the early 1970s, 75% of the observed global mean sea level rise can be explained by ocean thermal expansion due to climate warming and loss of glacier ice.
