The BBC documentary series Frozen Planet is about both the Arctic and Antarctic polar regions. The series includes seven episodes, but the last episode called "On Thin Ice" will not be airing on the Discovery Channel in the US. It is not because the episode is about climate change, but rather Discover Channel said it is not being aired due to them only scheduling six time slots for the series. However, some of the footage from the last episode will be put into the six episode and all episode will be available when the series is released on DVD in the United States.
Frozen Planet has already started airing on the BBC in UK and the Nine Network in Australia. It is scheduled to premiere in February 2012 on the Discovery Channel in the US.
