More than 40% of Antarctica’s ice shelves have dwindled in the past 25 years, potentially accelerating sea-level rise by allowing more land ice to flow into the ocean, according to new research released Thursday. The extent of ice shelves thinning is more widespread than previously thought, the results show, providing increasing evidence that the continent is feeling the effects of higher global temperatures. The Antarctic and Greenland ice sheets are responsible for more than one-third of the total sea-level rise in recent decades.
