The net loss in volume and hence
sea level contribution of the Greenland Ice Sheet (GIS) has doubled in recent years from 90 to 220 cubic kilometers / year has been noted recently (Rignot and Kanagaratnam, 2007).
This report, published in late September, projects Antarctica's
total sea level contribution to be up to 16 centimeters within this century.
Retreating tidewater glaciers dominate the
Alaskan sea level contribution due to their ability to efficiently transfer mass via iceberg calving [Arendt et al., 2002].
Accurate Attribution of Groundwater Discharge and Recharge Will Constrain Sea Level Contributions
Its report, published in September 2013, says Antarctica's
total sea level contribution could be up to 16 centimeters (6 inches) during this century.
It is found that the incomplete tide gauge observations result in posterior correlations between
individual sea level contributions, making robust separation of the individual components impossible.
Abstract
The sea level contribution from glacial sources has been accelerating during the 21st Century.
At present, both ice sheets are shrinking, but the rate is small (in terms of
sea level contribution, on the order of about 1 millimeter per year).
Its report, published in September 2013, says Antarctica's total
sea level contribution could be up to 16 centimetres during this century.
If Sahagian s assumption were applied to the inventory of Gornitz et al. it would imply
a sea level contribution of 0.2 to 1.0 mm / yr.
