Environmental activists led by Al Gore announced plans for a worldwide string of pop concerts in July to mobilise action against global warming.
The Live Earth concerts on July 7th will take place in Shanghai, Sydney, Johannesburg, London and cities to be decided in Brazil, Japan and the United States. There also will be a live performance in Antarctica.
The shows will feature more than 100 of the world's top musical acts, organisers said. In addition to Sheryl
Crow and the Red Hot Chili Peppers, US artists who have signed up include Black Eyed Peas, Bon Jovi, Kelly Clarkson, Faith Hill, Tim McGraw and rapper Snoop Dogg.
Organisers of the concerts and the new campaign Save Our Selves (SOS) hope to reach a global audience of some two billion people through concert attendance, radio, television and Internet broadcasts.
"We are launching SOS and Live Earth to begin a process of communication that will mobilise people all over the world to take action," Mr Gore said.
"The climate crisis will only be stopped by an unprecedented and sustained global movement. We hope to jump-start that movement right here, right now, and take it to a new level on July 7, 2007," he said.
Mr Gore, who lost his bid for US president in 2000, has since become one of the most visible activists on global warming. His An Inconvenient Truthdocumentary has been nominated for an Oscar at the February 25 Academy Awards
