Gore unveils Live Earth.

“Al Gore announced on Thursday a series of worldwide concerts to focus on the threat of climate change, with a powerhouse lineup from the Red Hot Chili Peppers to Snoop Dogg to Bon Jovi.” The 24-hour event on 7/07/07 is part of a campaign called Save Our Selves (SOS) — The Campaign for a Climate in Crisis. “In order to solve the climate crisis, we have to reach billions of people,” Gore said today. “The climate crisis will only be stopped by an unprecedented and sustained global movement.”
