A hidden threat is emerging in the worlds glaciers: while most are shrinking, a rare group known as surging glaciers can suddenly accelerate, unleashing powerful and sometimes destructive events. Scientists have identified over 3,100 of these glaciers worldwide, with many clustered in high-risk regions like the Arctic and the Karakoram Mountains, where communities lie directly in their path.
