Zemp, Michael; Huss, Matthias; Eckert, Nicolas; Thibert, Emmanuel; Paul, Frank; Nussbaumer, Samuel U; Gärtner-Roer, Isabelle (2020). Brief communication: Ad hoc estimation of glacier contributions to sea-level rise from the latest glaciological observations. The Cryosphere, 14(3):1043-1050.

Abstract

Comprehensive assessments of global glaciermass changes based on a variety of observations and prevail-ing methodologies have been published at multi-annual inter-vals. For the years in between, the glaciological method pro-vides annual observations of specific mass changes but is sus-pected to not be representative at the regional to global scalesdue to uneven glacier distribution with respect to the fullsample. Here, we present a simple approach to estimate andcorrect for this bias in the glaciological sample and, hence,to provide an ad hoc estimate of global glacier mass changesand corresponding sea-level equivalents for the latest years,i.e. about−300±250 Gt in 2016/17 and−500±200 Gt in2017/18.
