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.

Paradiesgletscher is the 89th-largest glacier in Switzerland, covering 1.88 km² in the canton of Graubünden. Its ice spans 2,554 to 3,162 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 6.00 km²; by 2016 it had lost 69% of that area. Its tongue has been measured 112 times since 1873. In total it has retreated 3,147 m, about 20.8 m a year. Between 1983 and 2024 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 2046. 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”.
