CO2

May 14, 2007 -  A study released on May 11, 2007 provides some of the first solid evidence that warming-induced changes in ocean circulation at the end of the last Ice Age caused vast quantities of ancient carbon dioxide to belch from the deep sea into the atmosphere. Scientists believe the carbon dioxide (CO2) releases helped propel the world into further warming.

River nourishes unexpected plant life, trapping greenhouse gas

Nutrients washed out of the Amazon River are powering huge amounts of previously unexpected plant life far out to sea...

Proposed Method Would Speed Natural Reactions a Million Times

Scientists say that a type of rock found at or near the surface in the Mideast nation of Oman and other areas around the world could be harnessed to soak up huge quantities of globe-warming carbon dioxide.

6,000 Square Miles in U.S. Might Turn Emissions to Harmless Solids 

To slow global warming, scientists are exploring ways to pull carbon dioxide from the air and safely lock it away.

A power plant in Iceland is set to become the first in the world to try turning carbon dioxide emissions into solid minerals underground, starting this September.

In an $11 million pilot project, Reykjavik Energy will capture CO2 from its plant, dissolve the gas in water and inject it deep into volcanic basalt nearby. Over the nine-month study, some 2,000 tons of greenhouse gas will be treated.

Researchers have reconstructed atmospheric carbon dioxide levels over the past 2.1 million years in the sharpest detail yet, shedding new light on its role in the earth’s cycles of cooling and warming.

The world’s oceans are growing more acidic as carbon emissions from the modern world are absorbed by the sea. A new film, “A Sea Change,” explores what this changing chemistry means for fish and the one billion people who rely on them for food. This first-ever documentary about ocean acidification is told through the eyes of a retired history teacher who reads about the problem in a piece in The New Yorker and is inspired to find out more. His quest takes him to Alaska, California, Washington and Norway to talk with oceanographers, climatologists and others.

Each person on the planet produced 1.3 tons of carbon last year—an all-time high--despite a global recession that slowed the growth of fossil fuel emissions for the first time this decade, according to a report published this week in the journal Nature Geoscience. Emissions grew 2 percent last year, to total 8.7 billion tons of carbon dioxide.
