Five times, the Earth has faced apocalyptic events. Cataclysms that have swept away all life forms, or almost. Each time, a handful of species has survived, establishing a new world. What did these prehistoric worlds look like? What catastrophes led to their disappearance? How did our distant ancestors manage to survive the five mass extinctions that the Earth has suffered, finally giving rise to the world we know today?
Combining CGI of ancient animal and plant life, VFX and filming, 'Prehistoric Worlds' looks back at the five mass extinctions of life on Earth that allowed the advent of the human race. On the brink of a sixth mass extinction that the scientific community considers imminent – this time caused by mankind – this film gives us an interesting and powerful look at Man's existence on the scale of the history of our planet.

Global warming, and how to combat it, has provoked intense debate, changed the way we see the planet and created headlines around the world. But when and how did scientists first discover global warming, why has it led to such furious debate? In this three-part series geologist Dr Iain Stewart presents a definitive guide to the history of climate change.
Battle Begins uncovers some of the great unsung heroes of climate change science, and introduces us to a secret organisation of American government scientists, known as Jason, who wrote the first official report on global warming as far back as 1979. By the late 1980s global warming had already become a serious political issue. It looked as if the world was uniting to take action. But it turned out to be a false dawn.

An Ice Age relic found in a mysterious cave is evidence of prehistoric humans' connection to the supernatural. Using cutting-edge tech, experts investigate this 40,000-year-old treasure to reveal why it was made and the long-lost myths it represents.
In the summer of 1939, a team of explorers unearthed hundred of mammoth ivory fragments within a cave in Germany. Due to the start of World War II, the explorers were forced to abandon their findings, and the fragments laid forgotten in a museum. Decades later, as archeologists began piecing the fragments together, an extraordinary artifact emerged -- a figure with both animal and human features, now known as the 'Lion man.'

Are rising temperatures driving Earth's ecosystems past a point of no return? We have promising technologies that put solutions within our grasp. Scientists are exploring solutions: from geoengineering to sucking carbon out of the air to cloud brightening, as means to cool the planet. Cutting-edge solutions and high-risk measures. But would they work? And what are the risks of engineering Earth's climate?

Peter Jackson's poignant WWI documentary 'They Shall Not Grow Old' to commemorate the centennial of the end of the first World War. The acclaimed documentary is an extraordinary look at the soldiers and events of the Great War, using film footage captured at the time, now presented as the world has never seen. By utilizing state-of-the-art restoration, colorization and 3D technologies, and pulling from 600 hours of BBC archival interviews, Jackson puts forth an intensely gripping, immersive and authentic experience through the eyes and voices of the British soldiers who lived it. Jackson recorded a special introduction to the film offering his perspective on why the film is important for audiences, who have never experienced WWI footage as anything but grainy black & white, and silent. Jackson opens a window to the past in a way that has never been seen or heard before, noting, 'Restoration is a humanizing process.'

What sort of alien civilizations might exist in the vastness of space? Terra is the fictional world imagined in Episode 4, a planet nine billion years old, twice as old as Earth. Old enough that a truly advanced intelligence could evolve. It was once a fertile world, now it is barren. But life can still thrive here in artificial domes. Over time, they've evolved not to need their bodies. They exist only as neural tissue. They never age, they never die. They're monitored and maintained by robots.
If alien civilizations are statistically so likely, why haven't astronomers found any sign of them? Where is everyone? Every time we look at an individual star, that's like dropping a bucket in the ocean. We're going to have to look at a lot of stars and to search through a lot of data until we find the clue that leads us to another civilization.
