Is Wall Street missing the biggest economic risk in the world?
That's what a trio of prominent hedge fund managers believe. Jeremy Grantham of $117 billion GMO, Chris Hohn of nearly $8 billion The Children's Investment Fund Management, and Steve Mandel of $27 billion Lone Pine Capital are giving millions of dollars to try and change it.
Each elite investor has given at least $1.5 million to back a new documentary series focused on the ramifications of global warming, "Years of Living Dangerously," which premiered on Showtime April 13.
The series is a collaboration with some of the biggest names in Hollywood. "Titanic" and "Avatar" director James Cameron, former United Artists head Jerry Weintraub, and actor-turned-politician Arnold Schwarzenegger are among the executive producers. Each episode features celebrity correspondents such as Matt Damon, Harrison Ford, Jessica Alba and Leslie Stahl.
