Best Slideshow

The Oscars are coming. As you may know, Al Gore's documentary An Inconvenient Truth was nominated for Academy Awards for Best Documentary Feature and Best Original Song. This week on Sierra Club radio, host Orli Cotel talks with director Davis Guggenheim about working with Al Gore, the movie star, and what it's like to be feted at Cannes, Sundance, and now the Oscars -- for a documentary! About a slideshow! Plus: Green Valentines Day tips; Mr. Green on giving up meat (or not); Carl Pope on the latest global warming report; and Zipcars -- a great new way to get around.
