In an epic three-part documentary series, FRONTLINE investigates the decades-long failure to confront the threat of climate change and the role of the fossil fuel industry. Part, One charts the fossil fuel industry’s early research on climate change and investigates industry efforts to sow seeds of doubt about the science. Part Two explores the industry’s efforts to stall climate policy, even as evidence about climate change grew more certain in the new millennium. And as leading climate scientists issue new warnings about climate change, Part Three examines how the fossil fuel industry worked to delay the transition to renewable energy sources — including by promoting natural gas as a cleaner alternative.

FRONTLINE and ProPublica go inside Europe’s fight against terrorism — the missed warnings and the lingering vulnerabilities.

Right-wing extremist acts of violence are increasing in Germany. The documentary traces how extremists have developed plans of overthrow and have carried out terrorist plots as well as assaults on Jews or migrants and also how far-right extremists infiltrated security services, which are actually there to protect the population and the state from such attacks. This raises the question of what the German authorities are doing to confront the growing problem and what options they have for action to counter the rising right-wing extremism in Germany. FRONTLINE journalist Evan Williams goes on a journey through Germany, meets the people involved and investigates these burning questions.
