PNAS Jord-, atmosf\u00e4rs- och planetvetenskap, 2 mars 2026<\/p>\n
Satellitradarobservationer fr\u00e5n 1992-2025 visar koncentrerade omr\u00e5den med snabb tillbakadragning av \u201cgrundst\u00f6tningslinjen\u201d, d\u00e4r detta massiva ist\u00e4cke m\u00f6ter havsbotten. Dessa regioner inkluderar Wilkes och George V Lands i \u00f6stra Antarktis; Bellingshausenhavet, Amundsenhavet och Getz Ice Shelf-sektorerna i v\u00e4stra Antarktis och den nord\u00f6stra och sydv\u00e4stra Antarktiska halv\u00f6n. Den mest extrema tillbakadragningen intr\u00e4ffade i Amundsen- och Getz-sektorerna i v\u00e4stra Antarktis, d\u00e4r grundst\u00f6tningslinjerna drog sig tillbaka upp till 42 kilometer vid Smith Glacier, 33 kilometer vid Pine Island Glacier och 26 kilometer vid Thwaites Glacier. I de omr\u00e5den d\u00e4r tillbakag\u00e5ngen \u00e4r som st\u00f6rst finns djupa dalar i havsbotten som leder varmt havsvatten mot grundst\u00f6tningszonerna, s\u00e4rskilt d\u00e4r botten lutar ned\u00e5t in\u00e5t land, vilket v\u00e4cker farh\u00e5gor om en snabbare framtida isf\u00f6rlust. Som helhet f\u00f6rlorade Antarktis \u00f6ver 12 000 kvadratkilometer grundad is mellan 1996 och 2025, varav 62% av f\u00f6rlusten intr\u00e4ffade i v\u00e4stra Antarktis och 28% i \u00f6stra Antarktis. Omkring 77% av Antarktis grundst\u00f6tningslinje har annars f\u00f6rblivit stabil under denna period.<\/p>\n
