Emissions hit all-time high as coal use takes dominant role

A JUMP in the use of coal to produce electricity, especially in China and India, has contributed to carbon emissions from human activities reaching an all-time record high, a study published today finds.With the faltering climate change talks set to open in Copenhagen next month, the latest figures from the Global Carbon Project show carbon dioxide emissions rising another 2 per cent last year as coal became the dominant source of fossil fuel emissions, taking over from oil for the first time in 40 years.Developing countries such as China and India have more than doubled their emissions since 1990 and now emit more than the developed world. But the richer countries still have a far higher rate of emissions per head, about four to five times the rate of the developing world.The rapid rise in emissions of carbon dioxide, a key greenhouse gas, is continuing at a rate that the peak United Nations scientific body, the Intergovernmental Panel on Climate Change, finds will lead to dangerous climate change."There is some bad news," said the CSIRO's Mike Raupach, a lead author of the study published in Nature Geoscience."CO2 [carbon dioxide] emissions from fossil fuel combustion are estimated to have increased 41 per cent above 1990 levels with emissions continuing to track close tothe worst-case scenario of the Intergovernmental Panel on Climate Change."If the current rate of emissions were to continue, Dr Raupach said, climate models projected global temperature rises of between three and four degrees by the end of the century. "That's obviously dangerous climate change by any measure."The beginning of the global financial crisis last year caused a slight slowing in emissions growth, pushing it down to a rise of 2 per cent last year; over the previous seven years the annual average rise had been 3.6 per cent. Dr Raupach said: "We will save about six weeks worth of emissions from the global financial crisis."The latest figures on carbon emissions are produced by 30 experts from international research institutions working with the Global Carbon Project, including the CSIRO. Among their findings is that the Earth's ability to absorb carbon emissions from the atmosphere, in the forests and oceans, appears to be decreasing. Over the past 50 years the amount of carbon dioxide emissions staying in the atmosphere appears to have increased from 40 per cent to 45 per cent.The latest figures for Australia, for 2008-09, show emissions from energy, industry and agriculture fell 1.2 per cent, said Dr Hugh Saddler, of Energy Strategies. As for the global figures, the drop was likely to be temporary, "mainly reflecting the economic slowdown".
