Surprise rise in warming gases worries experts

WASHINGTON - Worldwide industrial emissions of carbon dioxide — the main gas tied to manmade global warming — jumped 3 percent last year, international scientists said in a new report Thursday.

That means the world is spewing more carbon dioxide than the worst case scenario forecast by U.N. experts in 2007. Scientists said if the trend does not stop, it puts the world potentially on track for the highest predicted rises in temperature and sea level.

The pollution leader was China, followed by the United States, which past data show is the leader in emissions per capita in carbon dioxide output. And while several developed countries slightly cut their CO2 output in 2007, the United States churned out more, according to the Global Carbon Project, an initiative funded government science programs around the world.

Emissions in the United States rose nearly 2 percent in 2007, after declining the previous year. The U.S. produced 1.75 billion tons of carbon.

Gregg Marland, a senior staff scientist at the U.S. Department of Energy's Oak Ridge National Laboratory, said he was surprised at the results because he thought world emissions would drop due to the economic downturn. That didn't happen.
...
What is "kind of scary" is that the worldwide emissions growth is beyond the highest growth in fossil fuel predicted just two years ago by the U.N. Intergovernmental Panel on Climate Change, said Ben Santer, an atmospheric scientist at the Lawrence Livermore National Lab.

Under the panel's scenario then, temperatures would increase by somewhere between 4 and 11 degrees Fahrenheit by the year 2100.

The emissions, which are based on data from oil giant BP PLC and look at the burning of fossil fuel and production of cement, show that China has become the major driver of world trends. China emitted 2 billion tons of carbon last year, up 7.5 percent from the previous year.

"We're shipping jobs ashore from the U.S., but we're also shipping carbon dioxide emissions with them," Marland said. "China is making fertilizer and cement and steel and all of those are heavy energy-intensive industries."
...
Denmark's emissions dropped 8 percent. The United Kingdom and Germany reduced carbon dioxide pollution by 3 percent, while France and Australia cut it by 2 percent.
