The renowned sailing ship, SEDNA IV, returns home after a three-year voyage around the world, evaluating the state of the planet. From the Arctic to the Gulf of St. Lawrence, the crew document the important environmental changes taking place in areas they first visited in an expedition 15 years ago. The pack ice in the Arctic is melting faster and faster, and marine life in the St. Lawrence is struggling to adapt to the devastating effects of continual climate change.
