Carbon pollution up to 2 million pounds a second
By SETH BORENSTEIN, AP Science Writer
WASHINGTON (AP) The amount of heat-trapping pollution the world spewed rose again last year by 3 percent. So scientists say it's now unlikely that global warming can be limited to a couple of degrees, which is an international goal.
The overwhelming majority of the increase was from China, the world's biggest carbon dioxide polluter. Of the planet's top 10 polluters, the United States and Germany were the only countries that reduced their carbon dioxide emissions.
Last year, all the world's nations combined pumped nearly 38.2 billion tons of carbon dioxide into the air from the burning of fossil fuels such as coal and oil, according to new international calculations on global emissions published Sunday in the journal Nature Climate Change. That's about a billion tons more than the previous year.

Andrew Weaver, a climate scientist at the University of Victoria in Canada who was not part of the study, said: "We are losing control of our ability to get a handle on the global warming problem."

The latest pollution numbers, calculated by the Global Carbon Project, a joint venture of the Energy Department and the Norwegian Research Council, show that worldwide carbon dioxide levels are 54 percent higher than the 1990 baseline.
The 2011 figures for the biggest polluters:
1. China, up 10 percent to 10 billion tons.
2. United States, down 2 percent to 5.9 billion tons
3. India
