Northern Canada is warming more rapidly than any location on the planet, resulting in unprecedented ecosystem changes, widespread permafrost thaw, glacial retreat and an uncertain future. At the same time, development, primarily in the form of resource exploration and extraction, is placing additional pressure on sensitive ecosystems far from societal centres. Based on 25 years of northern travel and research, Dr. Sean Carey will review the unexpected changes that have occurred and how our collective water resources are threatened. Simply put, in a very short period of time, the north has changed. How Canadians will respond and adapt to this change remains uncertain.
