Gore and Intergovernmental Panel on Climate Change jointly awarded the Nobel Peace Prize
From 1993 to 2001, Gore was the forty-fifth Vice President of the United States, under Bill Clinton. Mr Gore, 59, has since devoted his efforts to environmental campaigning.
The UN's Intergovernmental Panel on Climate Change brings together the world's top climate scientists. The stated aims of the IPCC are to assess scientific information relevant to human-induced climate change, the impacts of human-induced climate change, and options for adaptation and mitigation.
The Nobel committee said it wanted to help the world focus on the threat it faced from climate change.
