That estimate was based in part on the fact that sea level is now rising 3.2 mm / yr (3.2 m / millennium)[57], an order of magnitude faster than the rate
during the prior several thousand years, with rapid
change of ice

During periods when ice

Rapid sea - level
changes (10 meters within 1000 years) were found in ancient coral reefs: Thompson and Goldstein (2005); Blanchon et al. (2009) found a «2 — 3 - m jump in sea level» in a century, presumably due to ice

during a period warmer than the 20th century.
However, substantial ice

From the Greenland cores there are two really important considerations; (1) ~ 130k DOES NOT get us back to the start of the last interglacial, from which one can infer that the Greenland
sheet may have completely melted away
during the inception and early millenia of the Eemian, and (2) the better resolution of Greenland ice (as opposed to Antarctic ice) has repeatedly shown that temperature
changes precede CO2
changes.
To a first approximation, sea - level
changes reflect the volume of ocean water bound in continental ice
sheets during the ice ages.
One implication is that if humans burn most of the fossil fuels, thus injecting into the atmosphere an amount of CO2 at least comparable to that injected
during the PETM, the CO2 would stay in the surface carbon reservoirs (atmosphere, ocean, soil, biosphere) for tens of thousands of years, long enough for the atmosphere, ocean and ice
sheets to fully respond to the
changed atmospheric composition.

During 2003 to 2008, the mass gain of the Antarctic ice

During the program, Beck put forth an apples - to - oranges comparison by suggesting that the 2007 Intergovernmental Panel on Climate
Change (IPCC) report contradicts Gore's statement in An Inconvenient Truth, that if the West Antarctic or Greenland ice
sheets were to break up or melt, «sea level worldwide would go up 20 feet»:
Based on ice -
sheet model simulations consistent with elevation
changes derived from a new Greenland ice core, the Greenland ice
sheet very likely contributed between 1.4 m and 4.3 m sea level equivalent, implying with medium confidence a contribution from the Antarctic ice
sheet to the global mean sea level
during the last interglacial period.
The assumption that the rate of
change of sea level rise from those components that were small
during the 20th century and which have been attributed to ice
sheets would scale with global temperature
change leads to a strong and unlimited amplification of future sea level rise when global temperatures continue to increase.
Ice
sheets will continue to react to climatic
change during the next several thousand years, even if the climate is stabilised.
