Briefings

Swiss glaciers experienced a catastrophic loss of nearly 20% of their mass over a five-year period, with 2026 marking the second-largest melt event on record. This decline disproportionately affects regions where glaciers are already most vulnerable to climate change, indicating accelerated ice loss rates compared to historical baselines.

Key points

• Swiss glaciers lost nearly 20% of their mass in five years, with 2026 registering the second-biggest melt on record.
• The loss rate is significantly higher than historical averages, reflecting the disproportionate vulnerability of Swiss glaciers to climate change.

Context and limitations

Data covers only the five-year period ending in 2026; specific regional breakdowns and long-term trends remain unquantified.
