Laughable alarmism and hysteria disseminated by the European Space Agency! Smells like junk science!
It only covers less than 25 years! What a joke! What if there a natural multi decadal fluctuations?
"... The research team... found that 71 ... ice shelves around Antarctica have reduced in volume, releasing almost 67 trillion tonnes of meltwater into the ocean. Apart from the issue of the ice shelves losing mass, this addition of freshwater into the ocean could have implications for ocean circulation patterns. ..."
From the abstract:
"Antarctic ice shelves moderate the contribution of the Antarctic Ice Sheet to global sea level rise; however, ice shelf health remains poorly constrained. Here, we present the annual mass budget of all Antarctic ice shelves from 1997 to 2021. Out of 162 ice shelves, 71 lost mass, 29 gained mass, and 62 did not change mass significantly. Of the shelves that lost mass, 68 had statistically significant negative mass trends, 48 lost more than 30% of their initial mass, and basal melting was the dominant contributor to that mass loss at a majority (68%). At many ice shelves, mass losses due to basal melting or iceberg calving were significantly positively correlated with grounding line discharge anomalies; however, the strength and form of this relationship varied substantially between ice shelves. Our results illustrate the utility of partitioning high-resolution ice shelf mass balance observations into its components to quantify the contributors to ice shelf mass change and the response of grounded ice."

Just look at the ESA image of Antarctica: 99% of the area unaffected. Gains and losses are very roughly balanced.
