Cumulative (a) specific and (b) total mass balances of glaciers and ice caps, calculated for large regions [Dyurgerov and Meier, 2005]. Specific mass balances signalize the strength of the glacier response to climatic change in each region. Total mass balances indicate each region’s contribution to sea level.
