Two episodes of the series that sends reporters into the most physically punishing corners of the planet. The first follows an estimated 165,000 Sahrawi refugees living in camps like El Aaiun, Awserd, Smara, and Dakhla in southwest Algeria's desert, where temperatures reach 50 degrees Celsius and, according to UNICEF, roughly 80 percent of residents are women and children. Crews walk the camps known locally as "The Devil's Garden," talking to families who have now spent decades as some of the longest-displaced refugees on earth. The second half travels to Greenland, home to 57,000 people and covered in ice across 85 percent of its land, to document how retreating snow cover, thinning coastal ice sheets, and shrinking Arctic sea ice are changing the terrain and threatening the Inuit way of life. Interviews with residents and scientists ground both segments, with handheld footage from inside the camps and out on the ice giving a firsthand sense of how people adapt when the environment turns hostile.
