Typically, the snout, margins, sides, and surface ice are below the pressure - melting point, while thicker ice higher up in the accumulation area is warm - based [3].

Winter snow tends to accumulate in the crevasses and gullies, so that at the end of winter there is already ice at the surface — so the melt season very close to the margin is very long.

I believe that what the phrase is trying to get at is either the acceleration relative to the pause in the 1950 - 1970 period, or the acceleration in accumulation of noticeable consequences — worldwide glacier melt, sea ice retreat, earlier onset of springtime, (possibly) increasingly intense hurricanes, Larsen - B breakup, melting of Greenland along the margins, etc..

At the very margins, this doesn't matter, what does matter is where ice is retained all summer but a lot of the top ice melts off, so the area doesn't change but the volume does.

Jonathan Bamber, director of the Bristol Glaciology Centre at the University of Bristol, UK, says: «We have already seen an unusually early start to melting around the margins of Greenland in 2016 and the new findings from NSIDC of exceptionally low sea ice extent for May and the lowest Northern Hemisphere snow cover in April for 50 years is in line with the longer - term, decadal trends for the Arctic as a whole,» said
