1 Summary of the balance years 2015/16, 2016/17 and 2017/18 (preliminary)
Mass balance values for the observation period 2015/16 and 2016/17 will be reported from more than 130 glaciers worldwide. The mass balance statistics (Table 1) are calculated based on all reported values and on available data from the 40 reference glaciers with continued observation series of more than 30 years (Table 2). In addition, preliminary mass balance values are given for 2017/18 for some glaciers.
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 1.0 meters water equivalent (m w.e.) during the hydrological year 2016/17. 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 almost 20 m w.e. (see Figures 1 and 2). All so far reported mass balance values, given in Table 3, are tentative.
Table 1: Overview on mass balance data 2015/16, 2016/17 and preliminary values for 2017/18. Statistics are given for all reported glaciers (ALL) and for the available ‘reference’ glaciers with continuous long-term observation series (REF).
