Climate change campaigner Al Gore and the UN's Intergovernmental Panel on Climate Change (IPCC) have been jointly awarded the Nobel Peace Prize for 2007.
The UN's IPCC, comprising 3,000 leading climate scientists, is the world's top authority on global warming.
The Nobel committee said it wanted to help the world focus on the threat it faced from climate change.
I think it is a good decision and timely. We must be very close to the 'tipping point' when sensible measures to avoid a runaway scenario may not work. Hope common sense prevails.
