In view of the upcoming IPCC Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC), we gathered an international team of experts to provide a new estimate of glacier contributions to global mean sea level. Here we present a new approach that combines the temporal variability from glaciological observations with improved spatial coverage from geodetic observations. Our new approach suggests that glaciers contributed 27 ± 22 mm to global mean sea-level rise from 1961 to 2016. Regional specific mass-change rates for 2006–2016 range between −0.1 and −1 .2 m water equivalent per year, resulting in a global sea-level contribution of 335 ± 144 Gt per year or 0.92 ± 0.39 mm per year. The current glacier mass loss is thus equivalent to the sea-level contribution of the Greenland Ice Sheet, clearly exceeds the loss from the Antarctic Ice Sheet, and accounts for 25% to 30% of the total observed sea-level rise.
