The scale and pace of change now taking place in West Antarctica is captured in a new, long-term satellite record.
Scientists have combined nearly a quarter of a century of observations to show how the region's great glaciers are losing height by up to 7m per year.
The satellite data also traces the way this thinning behaviour has spread up the length of the ice streams.
The glaciers concerned all terminate in the Amundsen Sea and are significant contributors to global ocean rise.
Their names are Pine Island, Thwaites, Pope, Smith, and Kohler.
