Madonna, the Beastie Boys and Black Eyed Peas will headline the concert at Wembley stadium in London. They will be joined by the Red Hot Chili Peppers, Keane, Foo Fighters and others.
Headliners for the U.S. concert at Giants Stadium in East Rutherford, N.J., include Bon Jovi, Dave Matthews Band, Kanye West, Rihanna, John Mayer, Smashing Pumpkins and Fall Out Boy, it was announced Tuesday.
Other shows will take place in Shanghai, China; Johannesburg, South Africa; Sydney, Australia; Tokyo; and Rio de Janeiro, Brazil.
Organizers have also promised an event in Antarctica.
The concerts mark the start of a new campaign called Save Our Selves, The Campaign for a Climate in Crisis.
"This monster lineup will ensure Live Earth meets our goal of bringing together people from around the world to combat the climate crisis," Live Earth Founder and Executive Producer Kevin Wall said in a statement Tuesday. "Musicians who have answered our call span multiple genres and generations."
The concerts will be broadcast in the U.S. by General Electric Co.'s NBC network and on more than 120 networks around the world, and streamed live online.
Promoters hope the concerts will reach an audience of 2 billion people. Proceeds will create a foundation to combat climate change led by The Alliance for Climate Protection, which is chaired by former Vice President Al Gore.
