Viewers will meet a daring, close-knit Canadian crew aboard the SEDNA IV, who set out to observe climate change and its consequences up close in the icy grip of Antarctica. This episode follows the crew as they embark on this spectacular adventure. Taking his lead from some of the world’s greatest explorers, mission leader Jean Lemire and his crew endured 17 months on the expedition to measure the threat posed by global warming in the Antarctic—a place where the Earth is particularly vulnerable.
