After one of the hottest years on record, Sir David Attenborough looks at the science of climate change and potential solutions to this global threat.

At the heart of the climate change debate is a paradox - we've never had more information about our changing climate, yet surveys show that the public are, if anything, getting less sure they understand what's going on.

Today, the topic of climate change is a major part of daily life, yet 40 years ago it was virtually unheard of. Since then, Horizon and the BBC have followed scientists as they have tried to unpick how the climate works and whether it is changing.

Rageh Omaar investigates how immigration has affected Britain. Using Enoch Powell's explosive 'Rivers of Blood' speech as a starting point, Rageh explores whether the apocalyptic visions of 40 years ago have any basis in today's reality.

As the UK gears up to decide its future in the June referendum, Nick Robinson explores the troubled history of the UK's relationship with Europe.

Documentary series exploring how we've become so reliant on oil in little longer than a human lifetime.

Documentary series exploring how we've become so reliant on oil in little longer than a human lifetime. In this series, Professor Iain Stewart visits the places that gave birth to the earth's oil riches, discovers the people who fought over its control and supply, and explores how our insatiable thirst for oil is changing the very planet on which we depend.

By the early 1950s, a holy trinity of oil, plastics and fertilisers had transformed the planet. But as Professor Iain Stewart reveals, when the oil producing countries demanded a greater share in profits from the Western energy companies, the oil and gas fields of the Middle East became a focus for coup d'états and military conflict.

As we entered the 21st century, the world was guzzling oil, coal and gas like never before. Despite fears of 'peak oil', Professor Iain Stewart discovers that while huge technological advances are helping extend the life of existing oilfields, new unconventional oil and gas supplies like shale gas and tar sands are extending the hydrocarbon age well into the 21st century.

The world's most famous living scientist talks exclusively about people's right to end their own lives if they are in great pain with no prospect of relief. He talks about the time doctors proposed turning off his life support machine and the need to protect vulnerable people. He also talks about his own thoughts on suicide.
