Years of Living Dangerously is an eight-part global warming documentary from James Cameron featuring celebrity correspondents like Harrison Ford, Olivia Munn and Matt Damon. It technically premieres April 13th, but you can already watch the first episode online.

Via the series' website:

The series combines the blockbuster storytelling styles of Hollywood's top movie makers, including James Cameron and Jerry Weintraub, with the investigative skills of 60 Minutes veterans Joel Bach and David Gelber and a team of leading national news journalists and scientists.

Each YEARS correspondent — including top Hollywood stars recognized for their commitment to spotlighting and acting on the biggest issues of our time — delves into a different impact of climate change. From the damage wrought by Hurricane Sandy in the tri-state area to political upheaval caused by droughts in the Middle East to the dangerous level of carbon emissions resulting from deforestation, the series takes the viewer on a journey to understand the current and intensifying effects of climate change through vivid stories of heartbreak, hope and heroism.

Just finished the first episode, and we're as on board with it now as we were when we first told you about it last year. Judging from the (generally) positive reception to this first installment, it looks like a lot of other people are, too. The show will air Sundays on Showtime.
