This is the trailer for Years Of Living Dangerously, a nine part documentary about the impacts of climate change by James Cameron and a bunch of Hollywood filmmakers, working with some of the USA’s top TV journalists and a team of top climate scientists. There are some big names involved: Harrison Ford, Matt Damon, Jessica Alba, and Arnold Schwarzenegger investigate various aspects of how climate impacts are already being felt. It’s being shown on Showtime (cable TV) in the US, and I imagine it will eventually turn up elsewhere around the world. For the time being you can watch the first episode in its entirety here:
For background info on how the Years Of Living Dangerously project was put together and financed, I recommend this excellent (long) article by Michael Peltz at Institutional Investor, Climate change and the years of investing dangerously, which looks at the work of Jeremy Grantham and others to persuade big business to take climate risks seriously.
