All over the world, scientists are discovering traces of ancient floods on a scale that dwarfs even the most severe flood disasters of recent times. What triggered these cataclysmic floods, and could they strike again? In the Channeled Scablands of Washington State, the level prairie gives way to bizarre, gargantuan rock formations: house-sized boulders seemingly dropped from the sky, a cliff carved by a waterfall twice the height of Niagara, and potholes large enough to swallow cars. Like forensic detectives at a crime scene, geologists study these strange features and reconstruct catastrophic Ice Age floods more powerful than all the world’s top ten rivers combined. NOVA follows their efforts to uncover the geologic fingerprints of other colossal megafloods in Iceland and, improbably, on the seabed of the English Channel. There, another deluge smashed through a land bridge connecting Britain and France hundreds of thousands of years ago and turned Britain into an island for the first time. These great disasters ripped through terrain and transformed continents in a matter of hours—and similar forces reawakened by climate change are posing an active threat to mountain communities throughout the world today.

Two-thirds of our planet is covered in water, split into five distinct oceans, but in reality, Earth's seas are part of one huge global water system - a system that has been instrumental in shaping our destiny for millions of years. Now, however, in the 21st century, it is mankind that is shaping the destiny of our oceans. In unprecedented ways, humans are changing our seas and the life within. The ocean bed, the currents, marine life, even the water itself is transformed by what we are putting into our oceans.

Iain Stewart investigates a new and controversial energy rush for the natural gas found deep underground. Sometimes, this is right under the places people live in. Getting it out of the ground involves hydraulic fracturing - or fracking. Iain travels to America to find to find out what it is, why it is a potential game changer and what we can learn from the US experience. He meets some of the people who have become rich from fracking as well as the communities worried about the risks.

As climate change begins to feel like an impossible challenge, this documentary tells the story of the first man-made threat to the planet's environment - the hole in the ozone layer - and how the world managed to fix it. The scientists and politicians at the heart of the story reveal how they spotted the giant hole in the stratosphere and, against all odds, persuaded Ronald Reagan and Margaret Thatcher - two of the most unlikely eco-warriors in history - to take action.

Adventurer and journalist Simon Reeve heads to one of the most spectacular countries in the world - Colombia. For 50 years, Colombia has been in the grip of a brutal civil war that has killed more than 200,000 people and displaced seven million. But in late 2016, a peace deal was signed promising to end the conflict and finally bring peace to the country. In this hour-long documentary for the award-winning This World strand, Simon explores Colombia at a pivotal point in its history. He travels into the jungle and comes face to face with the guerrilla army FARC, which is now promising to lay down arms. In the Pacific coast city of Buenaventura, Simon finds out more about the fearsome right-wing paramilitary gangs who now dominate the cocaine trade. As the FARC abandon the countryside, there is a fear that these groups will only grow in power. Travelling in the countryside, Simon meets the coca farmers who are demanding government support to stop growing coca and stop the flow of money to criminal gangs. With land ownership, poverty and drugs at the heart of Colombia's problems, it is in the countryside that the country's precarious future will be decided.
