A new study cited by multiple outlets reports that global sea levels may rise faster than previously expected due to the rapid melting of Antarctic ice shelves from beneath. Researchers analyzing the processes involved in ice-shelf melting conclude that warming ocean waters drive this undercutting more quickly than current assumptions often predict. As ice shelves lose mass, they can contribute to changes in the stability and flow of grounded ice upstream, which in turn can influence sea-level rise. The study, published in or referenced as appearing in *Nature Communications*, emphasizes that ocean-driven melting is a key mechanism that can intensify ice-loss rates. While the reports differ in emphasis and broader warnings, they converge on the central finding: Antarctic ice-shelf melt rates, particularly from below, appear to be faster than expected, implying that sea-level projections may need updating to reflect these dynamics. The claim is presented as a scientific forecast based on the observed and modeled effects of warming seas on ice shelves, with implications for future coastal flooding risk.
