Glaciers on a remote Australian subantarctic island are shrinking rapidly, losing almost a quarter of their size in just 70 years, with researchers fearing glaciers on a neighbouring peninsula may have already disappeared.
Analysis of aerial photographs and maps going back to 1947 were combined with satellite data to track melting on 29 glaciers on the uninhabited wilderness of Heard Island, 4,100km south-west of Perth and 1,500km north of Antarctica.
