The Live Earth concerts were a series of music concerts held in major cities around the world on July 7th to raise awareness about global warming. They took place in New York, Washington D.C., London, Johannesburg, Rio de Janeiro, Shanghai, Tokyo, Hamburg, and Sydney and included such high-profile music acts as Madonna, Smashing Pumpkins, Kelly Clarkston, Bon Jovi, Kanye West, Dave Matthews, Fall Out Boy, and The Police.
The event was largely credited to Al Gore, former Vice President and current Chair of the Alliance for Climate Protection that helped to coordinate the Live Earth concerts. He was the political and popular face of the concert event and so also became the brunt of most of the criticism surrounding it.
