Tällibodengletscher
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.
Tällibodengletscher is one of 1,400 glaciers in Switzerland, covering 0.05 km² in the canton of Valais. Its ice spans 2,664 to 2,925 m and faces north-west. Its meltwater drains to the Rhône and on to the Mediterranean. In 1850, at the end of the Little Ice Age, it covered 0.58 km²; by 2016 it had lost 91% of that area. Its tongue has been measured 55 times since 1922. In total it has retreated 367 m, about 5.2 m a year. Its mass balance has been measured since 1956: on average −0.25 m of water equivalent per year, with the most negative year in 1990 (−2.22 m). Between 1985 and 2023 its surface dropped by 15 m on average. With strong climate protection (SSP1-2.6), about 0% of its 2020 ice would remain in 2100. With very high emissions (SSP5-8.5) it would be gone around 2026. Its meltwater peaked around 2005.

Length change since 1922
Position of the glacier tongue, measured in the field almost every year. Hover for each measurement.
Mass balance 1956–1996
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 1985
Average change in surface height, from comparing elevation models made from maps, aerial images and laser scans.
