Extrapolating these melt rates forward to 2050, «the cumulative loss could raise sea level by 15 cm by 2050 ″ for a total of 32 cm (adding in 8 cm from glacial ice caps and 9 cm from thermal expansion)- a number very close to the best estimate of Vermeer & Rahmstorf (2009), derived by linking the observed rate of sea level rise to the observed warming.

Subtracting one from the other produced a «mass - balance» picture of net ice loss or growth for each ice sheet.

Ice shelves are important, because they play a role in the stability of the Antarctic Ice Sheet and the ice sheet's mass balance, and are important for ocean stratification and bottom water formation; this helps drive the world's thermohaline circulatiIce shelves are important, because they play a role in the stability of the Antarctic Ice Sheet and the ice sheet's mass balance, and are important for ocean stratification and bottom water formation; this helps drive the world's thermohaline circulatiIce Sheet and the ice sheet's mass balance, and are important for ocean stratification and bottom water formation; this helps drive the world's thermohaline circulatiice sheet's mass balance, and are important for ocean stratification and bottom water formation; this helps drive the world's thermohaline circulation.

I would also cite Zwally et al (2005) for evidence from the Greenland Ice Sheet and the East Antarctic Ice Sheet mass balances that are consistent with increasing winter precipitation and warmer temperatures.

If a negative surface mass balance were sustained for millennia, that would lead to virtually complete elimination of the Greenland ice sheet and a resulting contribution to sea level rise of about 7 m.

Postscript: A grouping of 40 + scientists, including four of our Nature co-authors, participated in the NASA / ESA Ice Sheet Mass Balance Intercomparison project (IMBIE) in an attempt to understand the reasons for previously disparate ice mass change estimatIce Sheet Mass Balance Intercomparison project (IMBIE) in an attempt to understand the reasons for previously disparate ice mass change estimatice mass change estimates.

The mass balance and d13C balance shows that vegetation as sink is not large enough to absorb all human CO2 if the oceans are a source and ice cores show that CO2 and temperature go to a (surprisingly linear) new equilibrium for every change in temperature level, not a sustained increase or decrease.

Because ice sheets contain so much ice and have the potential to raise or lower global sea level so dramatically, measuring the mass balance of the ice sheets and tracking any mass balance changes and their causes is very important for forecasting sea level rise.

Then in 2003 the launch of two new satellites, ICESat and GRACE, led to vast improvements in one of the methods for mass balance determination, volume change, and introduced the ability to conduct gravimetric measurements of ice sheet mass over time.

Given enough time, a negative net mass balance will ultimately lead to complete melting of the ice sheet, and several studies have attempted to quantify the climatic threshold and time period required for this to happen.

DMI says, The surface mass balance is calculated over a year from September 1st to August 31st (the end of the melt season) For the 2016 - 17 SMB year, which ended yesterday, the ice sheet had gained 544bn tonnes of ice, compared to an average for 1981 - 2010 of 368bn tonnFor the 2016 - 17 SMB year, which ended yesterday, the ice sheet had gained 544bn tonnes of ice, compared to an average for 1981 - 2010 of 368bn tonnfor 1981 - 2010 of 368bn tonnes.

When these factors are equal, the mass budget is balanced, but for years the Greenland Ice Sheet has had a negative mass budget, meaning the ice sheet is losing mass overaIce Sheet has had a negative mass budget, meaning the ice sheet is losing mass overaice sheet is losing mass overall.

The values for the Antarctic ice sheet mass balance from NASA GRACE are the most current available (to January 2017).

Going forwards, IMBIE provides a framework for assessing ice sheet mass balance, and has an explicit aim to widen participation to enable the entire scientific community to become involved.

And more recent estimates of the Antarctic mass balance contribution to sea level rise has the East Antarctica ice sheet gaining mass at a more accelerated pace for 2003 - 2013 than the mere +14 Gt per year identified by Shepherd et al. (2012) for 1992 - 2011.

Just a short list: — you go on and on about SMB causing a net reduction of sea level in Antarctica (and sometimes Greenland), completely ignoring that SMB is not the total ice mass balance — you routinely mentioned that human emissions aren't increasing the CO2 concentration because those emissions didn't increase for several years in a row, but concentration did.

Bamber has recalculated the critical threshold temperature for ice sheet melting by forcing two surface mass balance models with real future climate.

Hay et al. (2015) argue that rates of sea level rise between 1.0 and 1.4 mm yr - 1 close the sea - level budget for 1901 — 1990 as estimated in AR5, without appealing to an underestimation of individual contributions from ocean thermal expansion, glacier melting, or ice sheet mass balance.
