"Experts Surer Than Ever of Manmade Global Warming"
"OSLO -- Climate scientists are surer than ever that human activity is causing global warming, according to leaked drafts of a major UN report, but they are finding it harder than expected to predict the impact in specific regions in coming decades."
"The uncertainty is frustrating for government planners: the report by the Intergovernmental Panel on Climate Change (IPCC) is the main guide for states weighing multibillion-dollar shifts to renewable energy from fossil fuels, for coastal regions considering extra sea defenses or crop breeders developing heat-resistant strains.
Drafts seen by Reuters of the study by the UN panel of experts, due to be published next month, say it is at least 95 percent likely that human activities – chiefly the burning of fossil fuels – are the main cause of warming since the 1950s."
