1 Summary of the balance years |
| Preliminary mass balance values for the year 2006 are now available from more than 80 glaciers worldwide. The continuous mass balance statistics below are calculated based on the 30 glaciers in 9 mountain ranges*** with long-term data series back to 1980. The statistics for the year 2005 are based on 29 glaciers from 9 regions, and the preliminary values for the year 2006 result from 27 glaciers in 8 regions. The related statistics and figures will be updated as soon as the missing data becomes available. |
| The average mass balance of the glaciers with available long-term mass balance series around the world continues to decrease, with tentative figures indicating a further thickness reduction of 1.4 m w.e. during the hydrological year 2006. This continues the trend in accelerated ice loss during the past two and a half decades and brings the total loss since 1980 at more than 10.5 m w.e. |
| Results of the extreme and mean values for the year 2003/04, 2004/05, and 2005/06 have been calculated based on these 30, 29, and 27 glaciers, respectively: |
| . | 2003/04 | 2004/05 | 2005/06 |
| Mean (annual) specific net balance (mm w.e.) | -743 | -563 | -1301 |
| Standard deviation (mm w.e.) | 950 | 1042 | 859 |
| Minimum value (mm w.e.) | -2820 | -3280 | -3190 |
| Maximum value (mm w.e.) | 817 | 1098 | 560 |
| Positive balances (%) | 20 | 28 | 4 |
| The corresponding annual and cumulative mass balance results of this data set from glaciers in the Americas and Eurasia are visualized in the following two figures:
