<BIG>UN panel report blames human activities for global warming </BIG>

Human activities are heating the earth, risking more environmental disasters which will adversely affect mankind, warned a report by the United Nations climate panel on Friday.

It was "very likely" or there was a probability of more than 90 percent that human activities, chiefly the burning of fossil fuels, had caused the recorded warming in the past half century, said the final text of the report issued by the Intergovernmental Panel on Climate Change (IPCC), the world's most authoritative group on global warming. The accelerating global warming would result in more severe rains, melting glaciers, droughts, heat waves and rising sea levels, warned the IPCC, which groups some 2,500 scientists from more than 130 counties. The final text of the report, approved after overnight talks, is written in a much tougher tone than 2001's report in which the IPCC said the link was "likely" or the probability was 66 percent. The "increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations," said the report, which is a 21-page summary of scientific findings. The sea ice of the Arctic is "more likely than not" to melt during the summer by 2100, warned the report. The world's temperatures would go up by 1.8-4 Celsius degrees in the 21st century, predicted the IPCC, noting there had been a rise of 0.7 degrees in the 20th century. The group also said sea levels would rise by 18-59 centimeters in the 21st century. The report will add to the growing pressure on governments around the world to take more effective measures to combat climate change. </TD></TR></TBODY></TABLE>
