Filmed in eight countries on four continents, endorsed by dozens of the world's leading scientists, this three-hour television series is the most factually accurate, visually stunning and wide-ranging production ever mounted about this complex, fascinating subject.

Narrated by Alanis Morissette & Keanu Reeves, this three-part series, from the badlands of Alberta to Peru & around the world, examines the underlying science & evidence of climate change, it's legacy, the consequences of a "business as usual" scenario, and then sweeps around the world to introduce us to the people and communities who are combating The Great Warming.
