PBS today announced that AGES OF ICE, the three-part documentary series narrated by acclaimed Scottish actor David Tennant. The hour-long series is a high-stakes journey into the planet's frozen wilderness, revealing the extraordinary wildlife, breathtaking landscapes, and rapidly changing ecosystems of Earth's polar regions.

The Kimberley of PBS’s “Outback: The Kimberley Comes Alive” is so dazzling a world of wildlife, wild weather and archaeological marvels—not least the preserved footsteps of what were surely the most immense dinosaurs ever to tread the earth—it can feel impossible to keep up with it.
