Climate Scientists Find Huge Increase in CO2 Emissions

Researchers at the U.S. Department of Energy said that in 2010 the world produced 564 million more tons of greenhouse gases than it did in 2009, which represents an increase of 6 percent. That increase amount is greater than the individual emissions of all but three countries: China, the United States and India.

A substantial increase of CO2 output came from burning coal, the world's most significant carbon source. Coal-related emissions jumped by 8 percent in 2010. The overall result exceeded a worst-case expectation that was provided by the Intergovernmental Panel on Climate Change in 2007, when it described different scenarios for carbon dioxide pollution and noted that each scenario would be based on the level of pollution.

While greenhouse gas pollution remains a global problem, climate scientists pointed out that developing countries are more an issue. Andrew Weaver, a climate scientist at the University of Victoria in Canada said that 60 percent of emissions were caused by developed countries in 1990. Today, developing countries are responsible for more than 50 percent of emissions.

"We really need to get the developing world because if we don't, the problem is going to be running away from us," Weaver told the Sydney Morning Herald. "And the problem is pretty close from running away from us."
