Ice Worlds was a three-part series from company NHNZ, about the two frozen ends of the globe. The parts were 'Life at the Edge', 'Polar People', and climate episode 'Secrets of the Crystal Ball'. Narrated by Dougal Stevenson, they covered everything from the hibernation and breeding habits of polar bears to the unique properties of the Antarctic cod (also known as the Antarctic toothfish). The people who live and work on the poles are  acknowledged, as is the role the unique climate has played in developing such a unique environment.
