Former US Vice President Al Gore on Wednesday presented his documentary film on global warming, "An inconvenient truth," in Washington to an audience including members of Congress and Queen Noor of Jordan.
"This film gets a message across to as many people as possible in the shortest possible time," said Al Gore when he presented his documentary to the National Geographic Society.
Al Gore's film claims to show that global warming is imminent, and could have catastrophic consequences.
Harry Reid, leader of the Democratic minority in the Senate, took the opportunity to assure that the administration had made many mistakes, but "nothing compares to its ignorance of the death of our planet".
Queen Noor of Jordan, widow of King Hussein, born in the United States, told The Associated Press that the film was important because it was "objective, not partisan".
This premiere took place the day after the film's screening in Los Angeles, where a green carpet, instead of the traditional red carpet, had been rolled out to welcome an audience of artists, including the actors Sharon Stone or David Duchovny, or Olympic snowboard champion Shaun White.
