Limmerngletscher
Past extents come from the Swiss Glacier Inventories of 1850, 1931, 1973 and 2016. Future extents are illustrative: each glacier’s projected area (OGGM, median of CMIP6 climate models) is removed from its lowest ice upward. About the scenarios.
Limmerngletscher is the 83rd-largest glacier in Switzerland, covering 1.97 km² in the canton of Glarus. Its ice spans 2,210 to 3,410 m and faces north-east. Its meltwater drains to the Rhine and on to the North Sea. In 1850, at the end of the Little Ice Age, it covered 3.16 km²; by 2016 it had lost 38% of that area. Its tongue has been measured 57 times since 1945. In total it has retreated 338 m, about 4.3 m a year. Its mass balance has been measured since 1948: on average −0.17 m of water equivalent per year, with the most negative year in 1950 (−1.90 m). Between 1947 and 2022 its surface dropped by 30 m on average. With strong climate protection (SSP1-2.6), about 13% of its 2020 ice would remain in 2100. With very high emissions (SSP5-8.5) it would be gone around 2077. Its meltwater peaked around 2017.

Mass balance 1948–1985
Ice gained (blue) or lost (red) over the whole glacier each year, in metres of water equivalent. Measured with stakes drilled into the ice.
Thinning since 1947
Average change in surface height, from comparing elevation models made from maps, aerial images and laser scans.
