David Attenborough journeys to both Polar Regions to investigate what rising temperatures will mean for the people and wildlife that live there and for the rest of the planet. David starts out at the North Pole, standing on sea ice several metres thick, but which scientists predict could be Open Ocean within the next few decades. The Arctic has been warming at twice the global average, so David heads out with a Norwegian team to see what this means for polar bears. He comes face-to-face with a tranquilised female, and discovers that mothers and cubs are going hungry as the sea ice on which they hunt disappears. In Canada, Inuit hunters have seen with their own eyes what scientists have seen from space; the Arctic Ocean has lost 30% of its summer ice cover over the last 30 years. For some, the melting sea ice will allow access to trillions of dollars worth of oil, gas and minerals. For the rest of us, it means the planet will get warmer, as sea ice is important to reflect back the sun's energy. Next David travels to see what's happening to the ice on land: in Greenland, we follow intrepid ice scientists as they study giant waterfalls of meltwater, which are accelerating iceberg calving events, and ultimately leading to a rise in global sea level. Temperatures have also risen in the Antarctic - David returns to glaciers photographed by the Shackleton expedition and reveals a dramatic retreat over the past century. It's not just the ice that is changing - ice-loving adelie penguins are disappearing, and more temperate gentoo penguins are moving in. Finally, we see the first ever images of the largest recent natural event on our planet - the break up of the Wilkins Ice Shelf, an ice sheet the size of Jamaica, which shattered into hundreds of icebergs in 2009.

Takes us into the world of digestion and its amazingly complex environment.Our health, body shape, mood and even our evolution are determined by the unseen life forms that swarm throughout our bodies. There are worms in your bowels, bacteria in your mouth, fungi in your lungs and even viruses in your DNA.The combined genetic information of all these bugs is more than 150 times greater than our own genes. Their cells outnumber our own by 10 to 1. This collective menagerie is called the microbiome, and in a very real sense, it is the making of us all.

A Dog’s Life reveals how our best friends perceive the world - from the moment they take their first morning walk to the time they curl up at our feet to go to sleep. We accompany Daisy, a Jack Russell Terrier, through an average day and on the way discover that, while dogs are not miniature humans, they are amazingly well adapted to life with us. But how well do we know them? A Dog’s Life explores the widely assumed facts that may actually be based on faulty and out-dated research. Is your dog really like a wolf? Does she need you to be the “alpha” dog, so she knows where to fit into your pack? Do they really see in black and white? Is it true that dogs have an amazing sense of direction?

In the heart of south-east Asia lies the tropical island of Borneo. Twice the size of the British Isles, it is the third largest island on earth and home to possibly the greatest diversity of life of any island. Its huge variety of habitats, from bustling coral reefs and ancient jungles to towering mountains, have given rise to more than 60,000 species of plants and animals - many found nowhere else on Earth. This documentary covers Borneo's rich abundance of wildlife, from frogs to orang-utans.
