The acceleration of the rate of retreat since 1995 of key outlet glaciers of the Greenland and West Antarctic ice sheets may foreshadow a rise in sea level, which would affect coastal regions. The mass balance, or difference between accumulation and ablation (melting and sublimation), of a glacier is crucial to its survival. Climate change may cause variations in both
