Jörigletscher
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.
Jörigletscher is one of 1,400 glaciers in Switzerland, covering 0.12 km² in the canton of Graubünden. Its ice spans 2,694 to 2,916 m and faces north. Its meltwater drains to the Rhine and on to the North Sea. In 1850, at the end of the Little Ice Age, it covered 1.10 km²; by 2016 it had lost 89% of that area. Its tongue has been measured 6 times since 1895. In total it has retreated 47 m, about 4.3 m a year. Its mass balance has been measured since 2007: on average −1.05 m of water equivalent per year, with the most negative year in 2018 (−2.43 m). Between 1991 and 2022 its surface dropped by 16 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 2039. Its meltwater is projected to peak around 2026.

Length change since 1895
Position of the glacier tongue, measured in the field almost every year. Hover for each measurement.
Mass balance 2007–2019
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 1991
Average change in surface height, from comparing elevation models made from maps, aerial images and laser scans.
