preliminary glacier mass balance data 2011/2012


1   Summary of the balance year 2011/12

Preliminary mass balance values for the observation period 2011/12 have been reported now from more than 120 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 ten 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 0.6 metres water equivalent (m w.e.) during the hydrological year 2012. 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 16 m w.e. (see Figures 1 and 2). All so far reported mass balance values given in Table 3, are tentative.
