Swiss glaciers lose nearly twenty percent of volume since 2021
Slashdot reports that Swiss glaciers lost 5.5% of their total volume in the first eight months of 2026.
The short version
- Swiss glaciers experienced a 5.5% ice volume decline during the first eight months of 2026, bringing cumulative losses since 2021 to 19.4%.[Slashdot]
- Average individual glacier thickness shrank by 2.5 to 4 meters in 2026 following Switzerland's hottest and driest April-to-September period since 1864.[Slashdot]
- Researchers report that glaciers are increasingly collapsing from within due to sub-ice meltwater carving internal caverns rather than solely melting on the surface.[Slashdot]
Key facts
- Swiss glaciers lost 5.5% of their ice volume in the first eight months of 2026, reaching a total loss of 19.4% since 2021.[Slashdot]
- Individual Swiss glaciers experienced an average thickness loss of 2.5 to 4 meters in 2026.[Slashdot]
- MeteoSwiss analysis indicates the April-to-September period in 2026 was the warmest and driest recorded since tracking began in 1864.[Slashdot]
