Greenland melting rates

This is a very interesting short article, well worth reading -- giving us in a measured and informed fashion the lowdown on the smaller glaciers of Greenland -- ie those not associated with or connected to the ice sheet.  The news is not good........

This is a map from a previous publication, around 2011, which shows how ice surface elevations are changing.  Note the reductions in ice surface elevations by up to 40 cm per year near the coast, especially in SW Greenland, and the very dramatic melting all the way up the east coast.  In contrast, the ice surface elevation is increasing by up to 20 cm per year in the ice sheet interior.  That's because warm moist air is extenting further in towards the centre of the ice sheet, leading to increased precipitation and ice surface rise.  Overall, the result of these changes (which are ongoing) is an increased ice surface gradient on all the edges of the ice sheet.  That enhances the ice discharge rate, and this is enhanced even further by the huge volumes of meltwater now penetrating down to the glacier bed, increasing bed lubrication and facilitating bed slip and deformation.  All the glaciers are speeding up.... and the ice sheet volume is diminishing fast.
