Why do melting mountain glaciers represent a critical climate challenge? Glaciers worldwide have experienced dramatic ice loss since 2000, with Alpine glaciers alone losing nearly 40% of their mass. This phenomenon presents three major interconnected risks. First, glaciers serve as crucial freshwater reservoirs for billions of people. Their accelerated melt disrupts water availability for drinking, agriculture, and energy production, creating both flood and drought hazards. Second, mountain glac
