Ice arches supporting the Arctic's 'Last Ice Area' could COLLAPSE due to warming trends causing them to melt at twice the rate of the entire region The 'Last Ice Area' is a band of ice across Greenland and the Canadian Arctic Archipelago that is the oldest and thickest sea ice in the Arctic Ocean The region is held together by ice arches in the north and south areas Satellite data shows these ice arches are melting and shifting The duration of arch formation has decreased over the past 20 years Data also shows that the arches are melting twice as fast than any other ice
