Climate and science is covered by the British Broadcasting Corporation.
A wall of tumbling snow, rare tigers, and high-speed drones are some of the things that can be seen.
More than a decade on from the first series, Frozen Planet II returns, using new technology to give viewers an unprecedented insight into life in the coldest parts of our planet.
The six-part series took four and a half years to make.
"Natural phenomena never before seen by humans" is the result of the result.
The success of the series has led to a scientific publication on the Lapland bumble bee.
The first episode of the show will show a tiger prowling for food in caves in the winter, the first time this activity has been filmed.
It took three years to get them on camera, because they are so rare.
There is a benefit to waiting 11 years for a new series.
The emperor penguins were filmed using microscopes as they traveled to the sea. The cameras were supposed to catch a tiger moving. The NHU collaborated with experts to document the ice melt.
The NHU has never used a new generation of light-weight fast-response drones.
The terrifying first-hand experience of flying down the mountainside was captured.
The drones were used to document a mammoth ice calving.
The team was ready to send the drones nearly a mile across the ocean to reach the Store Glacier. The viewer is immersed in the blocks of ice as they break away from the glacier.
The executive producer of the series points out that Frozen Planet II draws attention to changes going on in the world.
Climate change has led to the loss of ice in the region six times faster than 30 years ago.
As the series producer Elizabeth White likes to refer to the animals, there is a lot of humor and pain.
It's easy to forget that the person behind the camera was also going through the same things.
According to Alex Lanchester, the camera operator who filmed the musk ox story had to camp out in the snow.
He lived in a garden shed on his Skidoo.
Filming in the most dangerous places on Earth can be difficult, but this was done during a global Pandemic.
A film crew had to stay in South Africa for 42 days before starting their trip toAntarctica.
The series brings some A-list quality to the soundtrack, despite the fact that the stars of Frozen Planet II are animals.
The music for the series was composed by Hans Zimmer, and a new song was written by Camila Cabello.
It's a dream come true to combine my passion for the planet we live on with my music.
Sir David's narration is very powerful as we try to protect these amazing environments.
