NOAA Arctic Report Card 2024 : Greenland Ice Sheet Greenland Ice Sheet

The Greenland Ice Sheet contains the equivalent of 7.4 meters of global sea level rise, currently frozen atop the world’s largest island (Morlighem et al. 2017). Ice sheet mass loss affects human and natural environments worldwide through coastal erosion, saltwater intrusion, habitat loss, heightened storm surges, tidal flooding, and permanent inundation. The Greenland Ice Sheet has experienced net-annual mass loss for 27 years running, for every year since 1998 (Poinar et al. 2023). It is currently the second largest contributor to sea-level rise, after ocean water thermal expansion due to warming (Zemp et al. 2019). We summarize the mass changes for the 2024 mass balance year, 1 September 2023 through 31 August 2024, and discuss influential factors.
