Attenborough's "Frozen Planet" has been re-scheduled for airing on the Discovery Channel. Delay of the release was the decision of the Channel, not 'censorship'.

The program has been criticized for misleading footage, e. g., the newborn polar bear cubs were filmed in a Dutch animal park, not in the wild.

Melting of sea ice and shifting habitats for polar bears and other wildlife has been well covered in a number of Nova and other US telecasts.
