Australian farmer John Weatherstone inspects a drinking trough on his drought-affected property near the southern-tablelands city of Goulburn, located 200 km (124 miles) southwest of Sydney February 2, 2007. The U.N. climate panel issued its strongest warning yet on Friday that human activities are heating the planet, putting extra pressure on governments to do more to combat accelerating global warming. The Intergovernmental Panel on Climate Change (IPCC), the most authoritative group on warming which groups 2,500 scientists from more than 130 nations, predicted more severe rains, melting glaciers, droughts and heatwaves and a slow rise in sea levels.
