The glacier melt has begun. According to initial calculations, the snow and ice that accumulated on Swiss glaciers over the winter has completely melted since Friday - the glaciers are now losing mass.

This was announced by glaciologist Matthias Huss at the request of the Keystone-SDA news agency. This point in time, when a glacier has lost the entire snow and ice reserve that has accumulated over the winter, is known as Glacier Loss Day (GLD).
The glacier loss day has only been reached as early as this year once before, as data from the Swiss glacier monitoring network Glamos shows: In the record year 2022, it was already on June 26.
Huss admitted that the GLD 2025 is currently an estimate that could still change by the end of the year. How much ice the Swiss glaciers will actually lose by the end of the melting period will now depend on the weather conditions over the next three months.
