Al Gore to be a guest on 'Letterman'

NEW YORK, Oct. 27 (UPI) -- Former U.S. Vice President Al Gore has agreed to be a guest on "Late Show with David Letterman," CBS said Tuesday.

The author and environmental activist is expected to make his sixth appearance on the "Letterman" episode to be broadcast Nov. 3.

"Gore will release his new book about the climate crisis, 'Our Choice: A Plan to Solve the Climate Crisis,' on the same day as his 'Late Show' appearance," CBS said in a news release. "The 45th vice president of the United States, who served with President Bill Clinton for eight years, Gore has also authored the bestsellers 'Earth in the Balance: Ecology and the Human Spirit,' 'An Inconvenient Truth' and 'The Assault on Reason.'"

Gore's documentary, "An Inconvenient Truth," won Academy Awards in 2007 for Best Documentary Feature and Best Original Song. Gore was a co-recipient of the Nobel Peace Prize in 2007 for his environmental work.

He is the co-founder and chairman of the cable news channel, Current TV.
