From NASA JPL: Cold Water Currently Slowing Fastest Thinning Greenland Glacier
NASA research shows that Jakobshavn Glacier, which has been Greenland’s fastest-flowing and fastest-thinning glacier for the last 20 years, has made an unexpected about-face. Jakobshavn is now flowing more slowly, thickening, and advancing toward the ocean instead of retreating farther inland. The glacier is still adding to global sea level rise – it continues to lose more ice to the ocean than it gains from snow accumulation – but at a slower rate.
The researchers conclude that the slowdown of this glacier, known in the Greenlandic language as Sermeq Kujalleq, occurred because an ocean current that brings water to the glacier’s ocean face grew much cooler in 2016. Water temperatures in the vicinity of the glacier are now colder than they have been since the mid-1980s.

As I reported last September, Greenland’s ice sheet mass balance had grown at close to record levels for the second year running.
To clarify again, the mass balance calculation accounts for:
2) Ice melt
In other words, it does not include calving.

Research study after research study has now proven beyond any doubt that the 350,000-square-mile subglacial Marie Byrd Mantle Plume and its associated geological features that are emitting massive amounts of ice melting heat and heated fluid onto the base of the Pine Island Glacier and Thwaites Glaciers.
Failure of the media to include in their numerous articles this telling scientific evidence which substantiates the significant and likely dominant role of this subglacial geologically induced heat flow in melting of West Antarctic glaciers is difficult to reconcile with proper scientific methodology.
A methodology which states that new and relevant data should be used to review old supposedly 100% settled theories.
Most of these research studies have been released one by one during the last three years which has led to minimizing their collective importance. Numerous previous Climate Change Dispatch articles written by this author beginning in 2014 have inexplicably been ignored by mainstream media outlets.
It’s time for the media to inform the public that by tying all this information together that a clear picture emerges concerning the significant impact of Antarctic subglacial geologically induced heat flow.

From ETH Zurich and the “slow as molasses in winter” department.
Hot summers cause glaciers to melt. That not only changes the makeup of the landscape and hence the maps of Switzerland, it also affects every area of society. A new, dynamic glacier inventory makes the impact of climate change and the changing landscape visible.
The last time Swiss glaciers managed to grow at all was in 2001. Since then, the country’s 1,500 glaciers – as well as others elsewhere – have been suffering a slow but inexorable death. Until now, though, we have understood only partially how quickly they are really disappearing, and what effect that has on the landscape, people and animals. That is about to change, thanks to the Glacier Monitoring in Switzerland (GLAMOS) project. GLAMOS is working on behalf of various Swiss federal offices to put together a comprehensive inventory of the country’s glaciers – at an unprecedented level of detail.

Earlier studies had documented little change in the western Ross coastline prior to 1995, and the new study both confirmed the earlier work and extended the analysis to the present time.
This work underscores the complexity of Antarctic climate change and glacier response.
