preliminary glacier mass balance data 2009/2010


1   Summary of the balance year 2009/10

Preliminary mass balance values for the observation period 2009/10 have been reported now from more than 100 glaciers worldwide. The mass balance statistics (Table 1) are calculated based on all reported values as well as on the data from the 37 reference glaciers in 10 mountain ranges (Table 2) with continuous observation series back to 1980.

The average mass balance of the glaciers with available long-term observation series around the world continues to be negative, with tentative figures indicating a further thickness reduction of 0.83 metres water equivalent (m w.e.) during the hydrological year 2010. The new data continues the global trend in strong ice loss over the past few decades and brings the cumulative average thickness loss of the reference glaciers since 1980 at about 15 m w.e. (see Figures 1 and 2). All so far reported mass balance values for the observation period, given in Table 3, are tentative.
