Research based on observations from the Gravity Recovery and Climate Experiment (GRACE) satellites (2002-2017) and GRACE Follow-On (since 2018 - ) indicates that between 2002 and 2025, Antarctica shed approximately 135 gigatons of ice per year, causing global sea level to rise by 0.4 millimeters per year.

These images, created from GRACE and GRACE-FO data, show changes in Antarctic ice mass since 2002. Orange and red shades indicate areas that lost ice mass, while light blue shades indicate areas that gained ice mass. White indicates areas where there has been very little or no change in ice mass since 2002. Areas in East Antarctica experienced modest amounts of mass gain due to increased snow accumulation. However, this gain is more than offset by significant ice mass loss on the West Antarctic Ice Sheet (dark red) over the 21-year period. Floating ice shelves whose mass change GRACE & GRACE-FO do not measure are colored gray.

The average flow lines (grey; created from satellite radar interferometry) of Antarctica’s ice converge into the locations of prominent outlet glaciers, and coincide with areas of highest mass loss (i.e., Pine Island and Thwaites glaciers in West-Antarctica). This supports other observations that warming ocean waters around Antarctica play a key role in contemporary ice mass loss.", "items": [], "extra_data": {} }, { "id": 312023, "url": "https://svs.gsfc.nasa.gov/31158/#media_group_312023", "widget": "Video player", "title": "", "caption": "", "description": "Animation showing Antarctic icesheet mass losses between 2002 and 2025.
