Albert Gore

Al Gore made waves for his work raising awareness on climate-change issues. Another poisonous environment has captured his attention as well: a climate that threatens reasonable public discourse.

For 17 years, former Vice President Al Gore has been on the forefront of warning against global warming. But in his new documentary, The Inconvenient Truth, he says that he "failed to get the message out." He's now getting the message out with his documentary and new book of the same name. The Washington Post calls the book "downright chilling." The documentary has been critically acclaimed.

Former senator, vice president, and presidential candidate Al Gore and his wife, Tipper. In the two years since the presidential election they have been working on the new book, Joined at the Heart: The Transformation of the American Family. The book explores the changes that have taken place in families over the past few decades, using examples of families the Gores have met along the way. Tipper Gore is a former photojournalist and served as adviser to the president on mental health policy. Their other book is the collection of photographs The Spirit of Family.
