FILE - In this Friday, Dec. 17, 2010 file photo, workers cycle past a coal-fired power plant on a tricycle cart in Changchun, in northeast China's Jilin province. The world's emissions of heat-trapping carbon dioxide took the biggest jump on record, the U.S. Department of Energy calculated, a sign of how feeble the world's efforts are at slowing man-made global warming. The new figures for 2010 mean that levels of greenhouse gases are higher than the worst case scenario outlined by climate change experts just four years ago. China, the United States and India are the world's top producers of greenhouse gases. Tom Boden, director of the Energy Department's Carbon Dioxide Information Analysis Center at Oak Ridge National Lab, said that in 2010 people were traveling, and manufacturing was back up worldwide, spurring the use of fossil fuels, the chief contributor of man-made climate change.
