Planet Earth: Frozen Planet II

"Frozen Planet II," narrated by David Attenborough, explores wildlife in some of the coldest regions found in the world. Premiering eleven years after the original series, "Frozen Planet II" benefits from the considerable advances in camera technology since the original. Whether capturing microscopic cracks in ice under baby penguins' feet, or using light-weight drones to follow an avalanche running down a mountain, a new set of eclectic visuals emerge that celebrates the colder regions and warns of what is lost in the face of global warming.
