carbon dioxide

Preliminary estimates from the International Energy Agency show that global carbon dioxide emissions in 2011 rose by 3.2 percent over 2010 levels, setting a record high of 31.6 gigatons.

North America has at least 500 years of storage in geologic formations that could accommodate carbon dioxide emissions from industrial sources.

More carbon is released from forest fire reduction practices than previously thought, according to a new study published in Frontiers in Ecology and the Environment.

The Department of Energy’s Carbon Dioxide Information Analysis Center estimates that 2010 was a record year for global CO₂ emissions from fossil fuel combustion and cement manufacture. The increase is about 5.9% above the 2009 global estimate. Emissions in the U.S.

Elevated CO₂ concentration increases production and growth of developing North American forest communities, according to a new study in Ecology Letters.

According to a recent report, global emissions of CO₂ increased by a record 5.8% between 2009 and 2010 due to continued growth in developing countries and economic recovery in industrialized countries.

A recent study in Climatic Change finds that the substitution of natural gas for coal initially increases global warming for many decades, rather than decreasing it as previously thought.
