The 5th IPCC Assessmnet report states that global mean sea level will continue to rise during the 21st century. Under all scenarios the rate of sea level rise will very likely exceed that observed during 1971–2010 due to increased ocean warming and increased loss of mass from glaciers and ice sheets.
The report states that the rate of rise could be 8-16mm per year by 2081-2100. Sea levels could be between 260 and 980mm higher than 2005 levels by 2100, depending on how much greenhouse gas we emit between now and then (the scenario used) and depending on the percentile figure taken.
