“A Cheyenne prophet named Sweet Medicine told us the Earth would burn,” Mann said. She added that she was thankful modern day scientists confirmed that temperatures were rising as her ancestors had warned.

Earlier this year, Sen. Jim Inhofe (R.-Okla.) led Republicans to successfully block Gore from obtaining a permit to hold a Live Earth concert on the National Mall because, according to one of his press aides, the event could be considered partisan and politically controversial.

The National American Indian Museum, which was already holding a day-long “Mother Earth” concert in conjunction with the annual Smithsonian Folklife Festival, agreed join with Live Earth. Washington, D.C. thus became a last minute add-on to the global concert series.

The event was perceived as both partisan and controversial by many. Men and women from conservative learning groups like FreedomWorks, Free Republic and Leadership Institute protested the event. A self-identified "freeper" named Kristinn Taylor, also a spokesman for the Memorial Day Gathering of Eagles event, held signs that read “Save the World, Kill the Terrorists” and “Live Earth is a Planet Killer.”

After leaving Washington, D.C., Gore traveled on an Acela train to New Jersey to attend another, much larger Live Earth Concert. There, a bevy of Top 40 pop stars like Kayne West, Kelly Clarkson, Alisha Keyes and others performed. At the New York Giants Stadium location, actor Leonardo DiCaprio introduced Gore as “a messenger of hope when we most need it.”

Other concerts were held in London, Johannesburg, Rio De Janeiro, Shanghai, Tokyo, Sydney and Hamburg.
