What can ice cores tell us about climate change, and how do we study them? We asked Dorthe Dahl-Jensen, Professor and Canada Excellence Research Chair. Earlier this year, researchers recovered the deepest ice core ever drilled in Canada, which will provide a roughly 10,000-year record of climate and sea conditions in the Canadian Arctic. Sections of this ice core have made their way to the Canadian Ice Core Laboratory at the University of Alberta, where they’re being closely studied. #UManitoba
