We are going back there to early Holocene glacier levels BUT
without the same forcings! β˜€οΈ 🌍

Gebroulaz Glacier 2025 mass balance πŸ§ŠπŸ“ˆ

The results for 2025 (-1.90 m w.e.) are the 3rd worst (after 2022 and 2023) since 2003 (ranked 7th!) ! πŸ”₯

Frontal retreat since 1980s is likely one of the smallest in the Alps (-250 m) due to an heavy debris cover!
