　　Global emissions（排放）of carbon dioxide from fossil fuel burning jumped by the largest amount on record in 2010. Emissions rose 5.9 percent in 2010, according to an analysis released on Sunday by the Global Carbon Project.

　　Scientists said the increase was almost certainly the largest absolute jump in any year since the Industrial Revolution. The increase solidified a trend of ever-rising emissions that will make it difficult, if not impossible, to stop severe climate change in coming decades.

　　The burning of coal represented more than half of the growth in emissions, the analysis found. In the United States, emissions dropped by a remarkable 7 percent in the year of 2009, but rose by over 4 percent in 2010, the new analysis shows.

　　“Each year, emissions go up, and there’s another year of negotiations, another year of indecision,” said Glen P. Peters, a researcher at the Center for International Climate and Environmental Research. “There’s no evidence that this path we’ve been following in the last 10 years is going to change.”
