Pharrell goes green

Flanked by hip-hop producer Pharrell and actress Cameron Diaz, former vice president Al Gore has announced an international campaign to promote global warming awareness.

Save Our Selves - The Campaign for a Climate in Crisis is focused on Live Earth, a 24-hour concert to take place on seven continents on July 7. More than 100 music acts, including Pharrell, John Legend, Black Eyed Peas, Fall Out Boy and Kelly Clarkson are scheduled to participate.

"This is the only issue in the history of mankind that affects every single one of us - our planet is in danger," Diaz told the audience gathered for the announcement. "But at least someone is doing something about it."

Promoters said the Live Earth concerts will take place in Shanghai, China; Johannesburg, South Africa; Sydney, Australia; London and cities to be announced in Japan, Brazil and the United States.

"We have a climate crisis that is a planetary emergency," said Gore, whose movie, An Inconvenient Truth, is nominated for two Oscars. "We have to respond. In order to that, we need to get the message of urgency and hope to billions of people around the world."

Pharrell, wearing his signature baggy jeans and a black cap pulled to the side, said, "Our atmosphere, our planet, is being abused, and we need to make this part of our daily consciousness."

Added Pharrell: "On July 7, you're going to see the biggest party on earth."
