Step 1: Context of the event
In recent years, accelerated climate change has led to rapid glacier retreat in the Alps, particularly in Switzerland.
Step 2: Data source
According to the Swiss Academy of Sciences (2023), Swiss glaciers lost 10% of their volume in just two years — 2022 and 2023 — due to heatwaves and lack of snowfall.
Step 3: Eliminate incorrect answers
Germany has minimal glacial coverage.
Greenland is losing ice but not with this specific statistic.
Antarctica’s changes are larger-scale but not directly related to the Swiss report.
So, Switzerland is the correct answer.
