Climate change warning from Beijing

The global growth in carbon dioxide emissions from fossil fuels was four times greater in the period between 2000 to 2005 than in the preceding 10 years, according to scientists gathering in

today for an international conference on global environmental change.

Despite efforts to reduce carbon emissions, the global growth rate in CO2 was 3.2% in the five years to 2005 compared to 0.8% in the period 1990 to 1999, according to data soon to be published by the Global Carbon Project, a component of the Earth System Science Partnership.

‘This is a very worrying sign,’ said Dr Mike Raupach, Chair of the Global Carbon Project. ‘It indicates that recent efforts to reduce emissions have virtually no impact on emissions growth and that effective caps are urgently needed.’

Carbon dioxide emissions over the last five years are said to be close to one of emissions scenarios from the Intergovernmental Panel on Climate Change (IPCC) called ‘A1B’. This scenario assumes that 50% of energy over the next century will come from fossil fuels, and leads to unacceptably high atmospheric CO2 concentrations.
