UN: World must end ‘dirty’ fuel use

A long-awaited UN report on how to curb climate change says the world must rapidly move away from carbon-intensive fuels, the BBC reports. There must be a “massive shift” to renewable energy, says the 33-page study released in Berlin. It has been finalised after a week of negotiations between scientists and government officials.
Natural gas is seen as a key bridge to move energy production away from oil and coal. But there have been battles between participants over who will pay for this energy transition.
The report is the work of the UN’s Intergovernmental Panel on Climate Change (IPCC), which was set up to provide a clear scientific view on climate change and its impacts. The Summary for Policymakers on mitigation paints a picture of a world with carbon emissions rising rapidly.”The high speed mitigation train needs to leave the station very soon, and all of global society will have to get on board,” the IPCC’s chair Rajendra Pachauri told journalists in Berlin at the launch of the report.
Dr Youba Sokono, a co-chair of the IPCC’s working group 3, which drew up the report, said science has spoken. He added that policy makers were “the navigators, they have to make decisions, scientists are the map makers”. The UK’s Energy and Climate Change Secretary Ed Davey told Sky News: “This is a stark warning that the world is looking down the precipice if we don’t take action now.” He added that the UK government was “leading the way” in Europe in encouraging the use of renewable energy sources, saying: “We’ve got to do a lot more and the world’s got to do a lot more.” About half of all the carbon that humans have pumped into the atmosphere since 1750 has been emitted in the last 40 years.
The report points to an increased use of coal in the decade from the turn of the millennium, “reversing the longstanding trend of decarbonisation of the world’s energy supply”. Driven by a global increase in population and economic activity, global surface temperature increases will be between 3.7C and 4.8C in 2100 if no new action is taken.
