A high Arctic ice refuge is more vulnerable than previously assumed, scientists say
The so-called "Last Ice Area" of northern Canada and Greenland might not hold sea ice as long as once thought.
At the far northern end of the Canadian Arctic Archipelago and along the shore of nearby Greenland, narrow Arctic Ocean channels between tightly spaced islands and headlands often hold thick, durable sea ice. Scientists have previously assumed sea ice will remain present in this area for longer into the future, even as it declines elsewhere, providing a refuge for ice-dependent animals such as polar bears.
