Frozen Planet is a nature documentary series, co-produced by the BBC, the Discovery Channel and The Open University. It was filmed by the BBC Natural History Unit. Other production partners are the Discovery Channel Canada, ZDF (Germany), Antena 3 (Spain) and Skai TV (Greece). The production team, which includes executive producer Alastair Fothergill and series producer Vanessa Berlowitz, were previously responsible for the award-winning series The Blue Planet (2001) and Planet Earth (2006), and Frozen Planet is billed as a sequel of sorts.[citation needed] David Attenborough returns as narrator, and the series was shot entirely in HD.
The seven-part series focuses on life and the environment in both the Arctic and Antarctic. The production team were keen to film a comprehensive record of the natural history of the polar regions, because climate change is affecting landforms such as glaciers, ice shelves, and the extent of sea ice.
