Here you can follow the accumulation - Greenland has a net accumulation of snow/ice every year - over the last months and years. This year has seen less melt/more accumulation than the average for the last 40 years. Go back to 2016 for the last period of high melt/low accumulation, 2010-2012 saw the highest melt/lowest accumulation in the last ~70 years. At this moment the runoff of water from Greenland is comparable to that in the 1950's [1 - select 'Run off' on polarportal.dk to get this graph].
As to why the authors suggest the application of the highest melt in 70 years - which, as is shown by the graph, clearly stands out from the rest - 'in perpetuity' I'll leave up to the readers to decide.

- olddustytrail 4y agoJust to ensure nobody is fooled by this idiot, the SMB clearly states: "It does not include the mass that is lost when glaciers calve off icebergs and melt as they come into contact with warm seawater. " English version at http://polarportal.dk/en/greenland/surface-conditions/ http://polarportal.dk/en/greenland/surface-conditions/
- the_third_wave 4y agoNice snub. Realise why those glaciers calve off icebergs - it is related to the flow of the glacier which is in turn a function of the amount of mass accumulated. As to those icebergs 'melting in contact with warm seawater' I can add that this is what icebergs do when they come into contact with seawater - they melt. Did you think they just stayed around forever to accumulate somewhere in a giant iceberg pileup? Nope, they melt and return the water to the ocean from where it eventually evaporates for a new cycle. So before you call someone an 'idiot' I'd suggest you read up on the subject so as to make yourself look like less of one.
