AFP – Earth’s climate appears to be changing more quickly and deeply than a benchmark UN report for policymakers predicted, top scientists said ahead of international climate talks starting Monday in Poland. Evidence published since the Intergovernmental Panel for Climate Change’s (IPCC) February 2007 report suggests that future global warming may be driven not just by things over which humans have a degree of control, such as burning fossil fuels or destroying forest, a half-dozen climate experts told AFP. Even without additional drivers, the IPCC has warned that current rates of greenhouse gas emissions, if unchecked, would unleash devastating droughts, floods and huge increases in human misery by century’s end. But the new studies, they say, indicate that human activity may be triggering powerful natural forces that would be nearly impossible to reverse and that could push temperatures up even further. At the top of the list for virtually all of the scientists canvassed was the rapid melting of the Arctic ice cap.
