IceIce lost since 1850This glacier

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.

Kinggletscher N is one of 1,400 glaciers in Switzerland, covering 1.17 km² in the canton of Valais. Its ice spans 3,034 to 4,461 m and faces west. Its meltwater drains to the Rhône and on to the Mediterranean. In 1850 it was part of a larger ice body of 3.5 km², which has since split into 3 glaciers covering 2.1 km² in 2016 (−40%). Between 1985 and 2024 its surface dropped by 17 m on average. With strong climate protection (SSP1-2.6), about 46% of its 2020 ice would remain in 2100. With very high emissions (SSP5-8.5) it would be gone around 2081. Its meltwater peaked around 2020.

Water leaving the glacier area each year: ice melt, snowmelt and rain. It rises while the glacier melts faster, then falls as the ice runs out: “peak water”.
