Frozen Planet

Frozen Planet finished filming in 2010 and focused on the challenges facing polar bears and Arctic wolves in the north and Adelie penguins and wandering albatrosses in the south, although many other storylines are developed.

The aerial photography used the Cineflex and Gyron cameras pioneered on Planet Earth, which enable steady footage to be captured from long range without disturbing the animals.

For the seventh programme, "On Thin Ice", he serves as writer and presenter for what was billed by the BBC as a personal statement on the effects of climate change at the poles.

A special programme called "Frozen Planet: The Epic Journey" featuring re-edited highlights from the series was broadcast on BBC One on 28 December 2011.

In the United States, Frozen Planet premiered on the Discovery Channel on 18 March 2012 with Alec Baldwin replacing David Attenborough as narrator of the first six episodes.

The Dolgan tribe of northern Russia is dependent on reindeer while the Inuit of Chukotka risk their lives hunting for walruses and collecting guillemot eggs.

In an interview with Radio Times, Attenborough explains that "data from satellites collected over the last 40 years show a drop of 30% in the area of the Arctic sea ice at the end of each summer.

"[31] Former UK Conservative politician Lord Lawson dismissed the idea as "alarmism", provoking a polar oceanographer working with the show to describe his criticism as "patronising", wrong and the "usual tired obfuscation and generalisation".

[36] In May 2012, Frozen Planet won in three categories at the British Academy Television Craft Awards, collecting prizes for best sound, best editing, and best photography.

[40] The following month, it won in three categories at the Wildscreen Festival in Bristol, UK, taking the Panda Awards for best sound, best cinematography, and best series, the latter shared with Human Planet.

In North America, the Blu-ray and Region 1 DVD box sets were released on 17 April 2012, and unlike the Discovery broadcast version, retained David Attenborough's original narration.

In addition, detailed profiles of the respective flora and fauna, geology and ice formations are provided as well as timelines of human exploration.
