Correcting this situation requires a predictive understanding of the processes responsible
for land ice loss.

2)
loss of
land based
ice: both
land based observations (Glacier National Park
for instance) and satellite gravity measurements make it clear that
land based
ice is decreasing.
The reasonable agreement in recent years between the observed rate of sea level rise and the sum of thermal expansion and
loss of
land ice suggests an upper limit
for the magnitude of change in
land - based water storage, which is relatively poorly known.
After extracting the influence of
land water storage, it is shown that the GMSL have been rising at a rate of 4.4 ± 0.5 mm / yr
for more than three years, due to an increase in the rate of both
land ice loss and steric change.
In combination, such
land -
ice losses today would see a rise in sea levels getting on
for fifteen metres over a number of centuries (which incidentally would mean the eventual
loss of most of Machynlleth).
re: «A complementary method
for determining and / or evaluating global sea level rise is a budget analysis that adds together the cumulative effect of the main contributors to sea level rise: thermal expansion, melting of
ice in glaciers,
ice loss from the Greenland and the Antarctic
ice sheets, and changes in
land water storage.»

Although, it does not agree well with most other measurement techniques, Wu et al's (2010) estimate is still at the upper end of IPCC predictions
for ice losses and shows extensive
land -
ice losses from both Antarctica and Greenland.
