(CBS) Self-avowed "P.R. agent for the planet" Al Gore says those who still doubt that global warming is caused by man - among them, Vice President Dick Cheney - are acting like the fringe groups who think the 1969 moon landing never really happened, or who once believed the world is flat.
The former vice president and former presidential candidate talks to 60 Minutes correspondent Lesley Stahl in an interview to be broadcast this Sunday, March 30, at 7 p.m. ET/PT.
Confronted by Stahl with the fact some prominent people, including the nation’s vice president, are not convinced that global warming is man-made, Gore responds: "You're talking about Dick Cheney. I think that those people are in such a tiny, tiny minority now with their point of view, they’re almost like the ones who still believe that the moon landing was staged in a movie lot in Arizona and those who believe the world is flat,” says Gore. "That demeans them a little bit, but it's not that far off," he tells Stahl.
Gore’s campaign to make the world more aware of man’s role in global warming won him the Nobel Peace Prize last year. He donated the $750,000 prize money to The Alliance for Climate Protection, the non-profit he started to help him on his quest. He and his wife, Tipper, tell Stahl they not only matched the Nobel money with their own, but they are also donating to the organization the significant profits from his book and Oscar-winning documentary film about global warming, "An Inconvenient Truth." The funds will help The Alliance for Climate Protection execute a new $300 million ad campaign on global warming set to start next week.
Some of the ads will feature unlikely alliances to drive home the message that people of all stripes are concerned about global warming. These include the Rev. Al Sharpton and the Rev. Pat Robertson, Toby Keith and the Dixie Chicks, and Nancy Pelosi and Newt Gingrich.
Stahl also visits the Gore's Nashville home, recently refitted with touches that include roof solar panels that make it more environmentally friendly. She asks him his feelings on the Supreme Court ruling that handed his opponent, George W. Bush, the electoral votes of Florida and the presidency.
Stahl also asks Gore, an uncommitted superdelegate of the Democratic Party, who he supports for his party’s nomination.
