Morteratsch Glacier: Sound artist captures final melt sounds as ice retreats

Sound artist Ludwig Berger is recording the sounds of the Morteratsch Glacier in Switzerland as it melts, documenting the acoustic signature of disappearing eternal ice. The piece highlights the ongoing retreat of Alpine glaciers due to climate change, though it is a cultural/artistic response rather than a new scientific measurement. The significance lies in public engagement with climate impacts, not in new data.
