Glacier cumulative mass balance

Description

Compilation of available data shows that most mountain glaciers are losing mass, and that the overall rate of mass loss has increased in the last decade. For the last decade the highest mass loss per unit area has been observed in the European Alps, Patagonia, Alaska, and north-western USA/south-western Canada (Kaser et al., 2006, Lemke et al., 2007, Arendt et al., 2009).
