Al Gore

On this day in 2007, former U.S. Vice President Al Gore and the United Nation’s Intergovernmental Panel on Climate Change were awarded the Nobel Peace Prize for their efforts to increase public knowledge about man-made climate change. In 2006, Gore had starred in the Academy Award-winning documentary An Inconvenient Truth. His documentary on climate change, nabbed an Academy Award for best documentary. (Although the Oscar actually went to director Davis Guggenheim, Gore gave an acceptance speech.) Gore's print version of An Inconvenient Truth won the Grammy for best spoken-word album, thanks to its release as an audio book.
