The figures are out for length changes of Alpine glaciers in 2015:http://glaciology.ethz.ch/messnetz/glacierlist.html
92 retreated, 4 advanced and 3 were stationary.
Unterer Grindelwald lost another 450 metres, which means that it has lost a few kilometres in the past few years. Many smaller glaciers also lost significant proportions of their length, but the main story is that almost all of the glaciers monitored are retreating, year after year after year.
For reference, here are the summaries for past years:
2014: Retreating 85, advancing 5, stationary 4
2013: Retreating 70, advancing 12, stationary 6
2012: Retreating 95, advancing 1, stationary 2
2011: Retreating 96, advancing 1, stationary 2
2010: Retreating 88, advancing 3, stationary 5
Note: total numbers of glaciers vary because not quite all glaciers are measured each year. The pattern of far more glaciers retreating than advancing goes back many decades, although it has been particularly strong in the last 20 years.
