The air around us is not just empty space; it is an integral part of the chemistry of life. Plants are made from carbon dioxide, nitrogen nourishes the soil and oxygen gives us the energy we need to keep our hearts pumping and our brains alive. But how did we come to understand what air is made of? How did we come to know that this invisible stuff around us contains anything at all?

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.

Something weird seems to be happening to our weather - it appears to be getting more extreme. In the past few years we have shivered through two record-breaking cold winters and parts of the country have experienced intense droughts and torrential floods. It is a pattern that appears to be playing out across the globe. Hurricane chasers are recording bigger storms and in Texas, record-breaking rain has been followed by record-breaking drought. Horizon follows the scientists who are trying to understand what's been happening to our weather and investigates if these extremes are a taste of what is to come.

From the global perspective of space, this 2-hour special reveals the breathtaking extent of our influence, revealing how we’ve transformed our planet and produced an interconnected world of extraordinary complexity. A journey through 12,000 years, Humanity from Space shows how seemingly small flashes of innovation have changed the course of civilization; innovations that touch all of us today in ways unimaginable to our ancestors. And we’ll gaze into the future at the new challenges we’ll face in order to survive as our global population soars because of our success. In every case we’ll look at our progression in a unique and surprising way, revealing unforgettable facts and "who knew?" connections. To visualize these stories cutting-edge technology is used to turn raw data into authentic moving images, building on expertise from a previous (and highly-praised) project; "Earth From Space." Using this technique, we can map humanity’s behavior in stunning, never seen before detail, revealing how our civilization grew, how it works today and what the future might hold.
