When in balance, the rate of iceberg calving (by area) is equalized by the seaward flow of the ice (see the essay on Greenland Ice Sheet Surface Velocity: New Data Sets, 2015 Arctic Report Card for further information on the velocity A study published in 2020 estimated, by combining 26 individual estimates of mass balance derived by tracking changes in Greenland's ice sheet volume, speed and gravity as part of the Ice Sheet Mass Balance Inter-comparison Exercise, that the Greenland Ice Sheet had lost a total of 3,902 gigatons (Gt) of ice between 1992 and 2018.

A mass balance of –234 ± 20 Gt a –1 (April 2002 to February 2012) was derived from Gravity Recovery and Climate Experiment (GRACE) data ( Reference 1 INTRODUCTION. Recent research highlights increased mass loss from the Greenland Ice Sheet (GrIS) (Shepherd et al., 2020; Hanna et al., 2013a; Hanna et al., 2020; Bamber et al., 2018), and the ice sheet's response to anthropogenic global warming includes a non‐linear effect of rising air temperatures on melt and runoff (Trusel et al., 2018).

Two thirds of the Greenland ice sheet's current mass loss stems from its surface mass budget with iceberg production accounting for the remaining mass loss. The focus of PROMICE is maintaining a network of automated climate stations in the ice sheet melt area to observe surface mass budget. When you look at the blue lines on the above graphs, it is quite evident that the Greenland Ice Sheet surface mass budget is far, far higher than the mean.

2017-01-02 · Greenland’s “surface mass budget” for winter 2016-2017 is already more than two standard deviations higher than the northern ice sheet’s mean snow and ice accumulation over the last 24 years. DMI data shows the ice sheet added 8 gigatons of ice and snow Jan. 1, well above the standard deviation for that day.

The focus of PROMICE is maintaining a network of automated climate stations in the ice sheet melt area to observe surface mass budget. When you look at the blue lines on the above graphs, it is quite evident that the Greenland Ice Sheet surface mass budget is far, far higher than the mean.

Strong deceleration in total mass balance (TMB) Next we consider both the SMB and the Discharge together. Here we see that Greenland’s total mass balance TMB (red curve) is negative, meaning a net ice loss in total, but has been decelerating since 2012.

Balancing act. Comparing the total snowfall and surface melt against each other gives you the “surface mass balance”. At the Danish Meteorological Institute (DMI), we use output from a numerical weather forecasting model combined with data from observation stations on Greenland to estimate the surface mass balance for the whole ice sheet for every single day. 2017-08-13 · Once the AMO enters its 30-yr cool cycle from around 2019, global temps start cooling from the 30-yr PDO cool cycle (which already started), additional global cooling occurs from the coming La Niña cycle, and even more cooling occurs from the approaching 50~100-year Grand Solar Minimum event, I think it’s highly likely 2017 could mark the turning point of gradual Arctic Sea Ice and net Since at least 2002, the total mass budget has been substantially negative, with the Greenland ice sheet losing around 200-300bn tonnes of ice each year. This year, thanks partly to Nicole’s snow and partly to the relatively low amounts of melt in the summer, we estimate the total mass budget to be close to zero and possibly even positive.

Greenland’s surface has gained 530 billion tons of ice since last summer, and is tracking well above normal.

Totalled over the course of a year, from 1 September to 31 August, this gives us the Daily (upper chart) and cumulative (lower) surface mass budget of the Greenland ice sheet, in billion tonnes per day, and billion tonnes, respectively. Blue lines show 2018-19 SMB year; the grey lines show the 1981-2010 average; and the red line in lower chart shows the record low SMB year of 2011-12. Credit: DMI Polar Portal.

Svårare än “Greenland ice sheet: Melting occurred across almost 40 percent of the DMI brukar vara alerta när det gäller Grönland och avsmältningen: Men but calving of icebergs also adds to the total mass budget of the ice sheet.

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 Balancing act.

27 Aug 2018 – This chart from the Danish Meteorological Institute (DMI) speaks for itself. The blue line shows Greenland ice-mass balance as of today. It is far, far greater than the mean – the average, if you will – from 1981 to 2010 (dark grey line). I doubt that you’ll see this reported by the mainstream media.
