For recent years, better estimates of the land ice contribution to sea level are available from various observations of glaciers, ice caps and ice sheets.
These values have been estimated using relatively simple climate models (one low - resolution AOGCM and several EMICs based on the best estimate of 3 °C climate sensitivity) and do not include contributions from melting ice sheets, glaciers and ice caps.
(A 2014 study by McMillan et al. examining CryoSat - 2 data more than doubled the estimated rate of Antarctic ice sheet contribution to sea level.
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.
IMBIE is an international collaboration of polar scientists, providing improved estimates of the ice sheet contribution to sea level rise.
As with IMBIE 2012, it will collate, compare, integrate, interpret, and report satellite estimates of ice sheet mass balance, with the overall aim of producing a community assessment of Greenland and Antarctica's ongoing contributions to global sea level rise.
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.
We take this as an estimate of the part of the present ice sheet mass imbalance that is due to recent ice flow acceleration (Section 4.6.3.2), and assume that this contribution will persist unchanged.
