Mass balance reference glaciers in nine mountain ranges
Hugo Ahlenius, UNEP/GRID-Arendal
Thirty reference glaciers with almost continuous
mass balance measurements since 1975
show an average annual mass loss of 0.58 m water
equivalent for the past decade (1996–2005), which is
more than twice the loss rate of the period 1986–1995
(0.25 m), and more than four times the rate of the
period 1976–1985 (0.14 m). The results from these
30 continuous mass balance series correspond well to
estimates based on a larger sample of more than 300
glaciers, including short and discontinuous series.
