Glatscher da Lavaz
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.
Glatscher da Lavaz is one of 1,400 glaciers in Switzerland, covering 0.64 km² in the canton of Graubünden. Its ice spans 2,360 to 3,060 m and faces north-east. Its meltwater drains to the Rhine and on to the North Sea. In 1850 it was part of a larger ice body of 3.3 km², which has since split into 2 glaciers covering 0.7 km² in 2016 (−80%). Its tongue has been measured 101 times since 1882. In total it has retreated 2,748 m, about 19.4 m a year. Between 1990 and 2022 its surface dropped by 25 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 2055. Its meltwater peaked around 2019.
