SLR by 2100 is more likely to come from ice mass loss from West Antarctica (WAIS) where warm ocean currents are already melting ice at glacier mouths and attacking areas of the WAIS resting on the seabed.

And since you have missed this acceleration you have assumed that the rate will remain at 3.3 mm / year for the rest of this century, despite ongoing observations of increases in ice mass loss in Greenland and parts of Antarctica.

The observed widespread warming of the atmosphere and ocean, together with ice mass loss, support the conclusion that it is extremely unlikely that global climate change of the past 50 years can be explained without external forcing, and very likely that it is not due to known natural causes alone.

Current models suggest ice mass losses increase with temperature more rapidly than gains due to increased precipitation and that the surface mass balance becomes negative (net ice loss) at a global average warming (relative to pre-industrial values) in excess of 1.9 to 4.6 °C.

Second, and less important but still rather spectacular, was the melting of virtually every square inch of the surface of this ice sheet over a short period of a few days during the hottest part of the summer, a phenomenon observed every few hundred years but nevertheless an ominous event considering that it happened just as the aforementioned record ice mass loss was being observed and measured.

Within a few years, the main outlet glacier draining the region — Zachariae Isstrom — retreated about 20 kilometers, and regional ice mass loss jumped from zero to roughly 10 metric gigatons a year.

«Once you have that combination of ocean heat and atmospheric heat — which are related — that's when the ice sheet could really experience dramatic ice mass loss.»

Blue represents ice mass loss, while red represents ice mass gain.

Gladstone et al. (2012) also investigated the future of PIG, and they too found ongoing ice mass loss to be likely under a «business as usual scenario» (IPCC), with full collapse of the main trunk of PIG during the 22nd century still a possibility.

and therefore to be able to make a stronger statement on how unique the current and apparently global warming related ice mass loss is» for Greenland, he says.

And «[b] oth ice sheets have seen an acceleration of ice mass loss since 2009,» the agency adds.

A high emission scenario shows increase of sea level rise for the next century, while in the low emissions simulation higher moisture holding capacity of the warmer air surrounding the Antarctic Ice Sheet leads to a snowfall increase, offsetting ice mass loss.

Between April 2002 and April 2006, GRACE data uncovered ice mass loss in Greenland of 248 ± 36 cubic kilometers per year, an amount equivalent to a global sea rise of 0.5 ± 0.1 millimeters per year.

The available record (Fig. 2) is too brief to provide an indication of the shape of future ice mass loss, but the data will become extremely useful as the record lengthens.

Consider the facts: the climate system is indicated to have left the natural cycle path; multiple lines of evidence and studies from different fields all point to the human fingerprint on current climate change; the convergence of these evidence lines include ice mass loss, pattern changes, ocean acidification, plant and species migration, isotopic signature of CO2, changes in atmospheric composition, and many others.
