IPPC report - Fossil fuels should be 'phased out by 2100'

The unrestricted use of fossil fuels should be phased out by 2100, if the world is to avoid dangerous climate change, a UN-backed expert panel says.

The Intergovernmental Panel on Climate Change's Synthesis Report summarises the causes, impacts of, and solutions to rising temperatures.

It says most of the world's electricity can - and must - be produced from low-carbon sources by 2050.
