The Last Ice Area may be in more peril than people thought. In a recent paper published in the journal Nature Communications, a Canadian research team describes how this multi-year ice is at risk not just of melting in place, but of floating southward into warmer regions. This would create an “ice deficit” and hasten the disappearance of the Last Ice Area. Details here.
