U.N. Science Panel Sees Faster Warming of Earth

Global warming is "unequivocal" and carbon dioxide already in the atmosphere commits the world to an average rise in sea levels of up to 4.6 feet, the world's top climate experts warned Saturday in their most authoritative report to date. The U.N. Intergovernmental Panel on Climate Change, which shared the Nobel Prize with Al Gore this year, released its final report Saturday at the end of the group's conference in Valencia, Spain. The report includes data and findings from three IPCC working groups on climate change and offers dozens of measures for avoiding the worst catastrophes if taken together — at a cost of less than 0.12 percent of the global economy annually until 2050. They range from switching to nuclear and gas-fired power stations, developing hybrid cars, using more efficient electrical appliances and managing cropland to store more carbon.
