«The fact that the mass loss of the Greenland Ice Sheet has generally increased over the last decades is well known,» Khan said, «but the increasing contribution from
the northeastern part of the ice sheet is new and very surprising.»
Indeed, if we closely look back at the map
of the «rising» /» falling» tide gauges in Figure 8, we can see that some areas which would have been under or near the
ice sheets during the glacial era show mostly «falling» trends (e.g., Fennoscandia in northern Europe, Alaska in US), while neighbouring areas show mostly «rising» trends (e.g., the
parts of northern Europe south
of Fennoscandia,
northeastern North America).
