Al Gore has arrived in Norway to receive his Nobel Peace Prize, and has immediately displayed his green credentials by choosing to take an airport shuttle rather than a limousine to travel into Oslo city centre.
The 2007 prize was jointly awarded in October to 59-year-old Gore and to the Intergovernmental Panel on Climate Change, a UN body of 3,000 scientists, for their work in highlighting global warming.
The award will be handed out at a ceremony on Monday.
