The main contribution to sea level change in the short-to-medium term is 
thermal expansion of the oceans, currently predicted to have reached about 
0.15 m over pre-industrial standards, and currently rising some 3 mm/year. 
Although the melting of inland ice in Greenland and Antarctica is reported, 
this will mainly have local effects, as this ice will possibly take 15-20,000 
years to have any significant contribution to sea levels. However, polar 
glaciation and sea ice is an important indicator of global warming, and in
