Trees could grow in Antarctica within century: scientist Wed Jul 12, SYDNEY (AFP) - Trees could be growing in the Antarctic within a century because of global warming, an international scientific conference heard. With carbon dioxide levels in the atmosphere set to double in the next 100 years, the icy continent could revert to how it looked about 40 million years ago, said Professor Robert Dunbar of Stanford University. "It was warm and there were bushes and there were trees," he told some 850 delegates in the Tasmanian capital Hobart, the national AAP news agency reported. The delegates are attending the combined meetings of the Scientific Committee on Antarctic Research and the Council of Managers of National Antarctic Programs. Dunbar said climate experts were predicting a doubling of the levels of carbon dioxide by 2100, "but it actually looks like it's going to come sooner unfortunately." Scientists blame greenhouse gases such as carbon dioxide, produced mainly by the burning of fossil fuels such as coal and oil, for causing rising temperatures worldwide.
