Trees Could Grow In Antarctica Within Century Says Scientist
Sydney (AFP) Jul 12, 2006 Trees could be growing in the Antarctic within a century because of global warming, an international scientific conference heard Wednesday. 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.

Alpine Glaciers Could All But Disappear Within This Century
Washington DC (SPX) Jul 10, 2006The European Alps could lose some 80 percent of their glacier cover by the end of this century, if summer air temperatures rise by three degrees Celsius. And if temperatures increase by five degrees Celsius, the Alps would become almost completely ice-free by 2100. |
