"Thanks to the readers of ActLocallySF.org, Mayor Newsom and the citizens of San Francisco for all of the hard work you are doing to solve the climate crisis.

On July 7th, Live Earth will mark the beginning of a three-year campaign that will mobilize people worldwide to take action to solve the climate crisis. Global warming can only be solved by an unprecedented and sustained global movement–but it has to start with you. We hope to jump-start that movement right here and right now.  I hope that you will join us on 7/7/07." — Al Gore

In between Oscar winning movies and Nobel prize nominations, Al Gore has undertaken yet another incredible effort to bring attention to the global climate crisis – Live Earth.

Live Earth is a 24-hour, 7-continent concert series taking place on 7/7/07 that will bring together more than 100 music artists and 2 billion people to trigger

Live Earth will reach this worldwide audience through an unprecedented global media architecture covering all media platforms - TV, radio, Internet and wireless channels.

Live Earth marks the beginning of a multi-year campaign led by the Alliance for Climate Protection, The Climate Group and other international organizations to drive individuals, corporations and governments to take action to solve global warming. Former U.S. Vice President Al Gore is the Chair of the Alliance and Partner of Live Earth.

Live Earth was founded by Kevin Wall, the Worldwide Executive Producer of Live 8, an event that brought together one of the largest audiences in history to combat poverty. Wall formed a partnership with Al Gore and the Alliance for Climate Protection to ensure that Live Earth inspires behavioral changes long after 7/7/07.

Live Earth will stage official concerts at Giants Stadium in New York; Wembley Stadium in London; Aussie Stadium in Sydney; Copacabana Beach in Rio de Janeiro; Maropeng at the Cradle of Humankind in Johannesburg; Makuhari Messe in Tokyo; the Steps of the Oriental Pearl Tower in Shanghai; and HSH Nordbank Arena in Hamburg.
