Growing like gangbusters - from the Danish Meteorological Institute:
Current Surface Mass Budget of the Greenland Ice Sheet
Here you can follow the daily surface mass balance on the Greenland Ice Sheet. The snow and ice model from one of DMI’s climate models is driven every six hours with snowfall, sunlight and other parameters from a research weather model for Greenland, Hirlam-Newsnow. We can thereby calculate the melting energy, refreezing of melt water and sublimation (snow that evaporates without melting first). The result of this is a change in the snow and ice from one day to the next and this change is shown below. All numbers are in water equivalent, that is, the amount of water the snow and ice would correspond to if it was melted.
The model has been updated in 2014 to better account for meltwater refreezing in the snow, and again in 2015 to account for the lower reflectivity of sunlight in bare ice than in snow. The update means that the new maps, values and curves will deviate from the previous ones. Everything shown on this site, however, is calculated with this new model, so that all curves and values are comparable.
Here is a chart that shows the growth and compares it to #1) - the last few years and #2) - the average from 1990 to 2013. Blue is this year:
Top: The total daily contribution to the surface mass balance from the entire ice sheet (blue line, Gt/day). Bottom: The accumulated surface mass balance from September 1st to now (blue line, Gt) and the season 2011-12 (red) which had very high summer melt in Greenland. For comparison, the mean curve from the period 1990-2013 is shown (dark grey). The same calendar day in each of the 24 years (in the period 1990-2013) will have its own value. These differences from year to year are illustrated by the light grey band. For each calendar day, however, the lowest and highest values of the 24 years have been left out.
More people die from excessive cold than from excessive heat. How much more data like this will people have to see to recognize Anthropogenic Global Warming for the political fraud that it is.
