NOAA Technical Report OAR ARC 23-05 ... : The Greenland Ice Sheet (GrIS) is the second-largest contributor of sea-level rise (SLR), after thermal expansion (Zemp et al. 2019). Ice mass loss from the GrIS affects environments and societies worldwide through coastal erosion, saltwater intrusion, habitat loss, increased flooding, and, in some locations, permanent inundation. In every year since 1998, the GrIS has lost mass overall. In the one-year period from 1 September 2022 to 31 August 2023, the GRACE-FO (Gravity Recovery and Climate Experiment Follow-on) satellite mission measured a total GrIS mass balance of -156 ± 22 Gt (mean ± 1 st. dev.), the equivalent of ~0.4 mm SLR (Fig. 1). This loss was 60 Gt (28%) less than the 2002-23 GrIS yearly average of -216 ± 8 Gt measured by GRACE/GRACE-FO. ...
