Besides Gore, who helped negotiate the 1997 climate treaty that failed to control global warming, the broadcast was to feature musical performances by Elton John, Duran Duran and others.

French President Francois Hollande and former U.N. Secretary-General Kofi Annan are among other officials scheduled to take part in the event.
