However, it is likely that the relatively high end of season SMB will mean a zero or close-to-zero total mass budget this year, as last year. The period 2003-2011 has seen ice sheet losses on Greenland averaging 234bn tonnes each year. The neutral mass change in the last two years does not – and cannot – begin to compensate for these losses.
In quantifying the association between Greenland coastal temperatures and Greenland Ice Sheet (GrIS) mass‐balance changes, we show a stronger link of temperatures with total mass balance rather than surface mass 2020-02-05 · There you have it… The insignificance of Greenland’s ice mass loss in five easy charts… And a lot of not so easy charts and tables. References. Alley, R.B. 2000. “The Younger Dryas cold interval as viewed from central Greenland”. Quaternary Science Reviews 19:213-226. The overall result is that the Greenland ice sheet is losing ice mass (Wouters et al. 2008).

DMI data shows the ice sheet added 8 gigatons of ice and snow Jan. 1, well above the standard deviation for that day. Previous uses of the DMI graph includes 'Greenland Ice Growth Ahead Of Last Year’s Record Pace' (Oct 2017) which seems oddly careful to specify that DMI does show surface mass balance given that it goes on to talk of 'criminals in the press and academia'; 'Record Greenland Ice Growth Continues' (Sep 2017); 'Scientists Discover That Their Imaginary Greenland Meltdown Is Not Having Any Effect Marine-terminating glaciers are the outlets via which the Greenland ice sheet discharges ice mass to the ocean.

Log In. or In 2018, Greenland’s total surface mass budget (SMB) is almost 150bn tonnes above the average for 1981-2010, ranking as sixth highest on record. 12 July 2018 THE GLOBAL WARMING POLICY FORUM — The Danish Meteorological Institute (DMI) also performs daily simulations of how much ice or water the Ice Sheet loses or accumulates. Greenland temperature changes are more strongly correlated with Greenland Blocking than with North Atlantic Oscillation changes.
