Former presidential candidate Al Gore is working on a sequel to his book about global warming, "An Inconvenient Truth."
It will be called "The Path to Survival" and will be released on April 22, which is Earth Day.
The former vice president will continue where he left off in "An Inconvenient Truth" and suggest changes that need to be made.
"An Inconvenient Truth" was released as a feature film in 2006 and won the Academy Award for best documentary.
The book topped the New York Times best-seller list for non-fiction paperbacks.
