One snippet from this link:
“During recent years (1993–2003), for which the observing
system is much better, thermal expansion and melting of land
ice each account for about half of the observed sea level rise,
although there is some uncertainty in the estimates.
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.”
From an earlier post on this same subject I tried to convert the water lost by comparing the square area of D.C. which would have been covered by water 1/2 mile deep; worked out to something like the melt of 8 feet of snow from the entire surface of Greenland.
Does anyone know the annual snowfall totals for Greenland?
