latest glacier mass balance data

1 Summary of the balance years 2017/18, 2018/19 and 2019/20 (preliminary)

Mass balance values for the observation periods 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. In addition, preliminary mass balance values are given for 2019/20 for some glaciers. The average mass balance of the glaciers with available long-term observation series around the world continues to be negative. 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. The current status of glaciers worldwide is summarized here. All so far reported mass balance values, given in Table 2, are tentative.

Table 1: Overview on mass balance data 2017/18, 2018/19 and preliminary values for 2019/20. Statistics are given for all reported glaciers (ALL) and for the available ‘reference’ glaciers with continuous long-term observation series (REF).
