The highest mountains on Earth are home to snow leopards, golden eagles, mountain goats, barnacle goslings, and gelada monkeys; only the toughest of animals can endure the extreme weather, scarce food supplies and limited oxygen on these peaks.
Antarctica - the coldest, windiest, most hostile continent. Only the toughest can survive here. From Weddell seals that grind back the ice with their teeth, to colourful starfish carpeting the seabed beneath the ice. Huge colonies of king penguins crowd any ice-free land, and four tonne elephant seals fight for territory on the beach. Life comes here because the ocean that surrounds the continent is incredibly rich. Thousands of penguins, seals, albatross, and over a hundred great whales feast on krill baitballs. However, the ocean here is warming and with that comes an uncertain future. (Number of days filming: 236)
Dr Helen Czerski peers into the heart of the storm to find out how advances in technology are giving new insight into tornadoes - the fastest winds on the planet. From the breathtaking footage that capture the extreme weather events that produce them, to the latest experiments investigating their incredible destructive power, Helen discovers how understanding the subtle changes deep within the storm are improving predictions of when and where these devastating beasts will strike.
The rains are late. It is the most brutal time of year. Babies born into drought face starvation. The weak and the injured are weeded out. Everything is desperate for rain. When it finally arrives, it is a downpour on an enormous scale. Alien creatures emerge into a different world. The wet season begins.
This episode discusses the human exploration of Antarctica, in particular the mission led by Captain Robert Falcon Scott, whose team died on the way back from the South Pole. It shows the scientific work in the modern human bases in Antarctica, especially Mawson Base and its observation of Adelie Penguins (partially through tracking devices).
