An aerial view shows the breakup of the Milne Ice Shelf in late July 2020 (left) and animals found living in its ice cavity (right) at the site boxed in red ().The ice shelf is in the so-called Last Ice Area, which observations and modeling show as the band of thickest sea ice in the Arctic Ocean that occurs along the northern coast of Canada and Greenland. According to Copland, the Arctic has been warming at twice the global rate over the past 30 years, and this process is known as Arctic amplification. .css-1xgx53b-Link{font-family:ReithSans,Helvetica,Arial,freesans,sans-serif;font-weight:700;-webkit-text-decoration:none;text-decoration:none;color:#FFFFFF;}.css-1xgx53b-Link:hover,.css-1xgx53b-Link:focus{-webkit-text-decoration:underline;text-decoration:underline;}Read about our approach to external linking.
