Two Rice University researchers are calling on policymakers to encourage the transition from coal-based electricity production to a system based on natural gas through a carbon tax. Such a mechanism would help limit carbon dioxide (CO2) emissions. At the United Nations Climate Change Conference in Copenhagen last December, the United States pledged to reduce the 2005 levels of CO2 emissions by 17 percent by 2020. Dagobert Brito, the George A. Peterkin Professor of Political Economy, and...

With carbon dioxide in the atmosphere approaching alarming levels, even halting emissions altogether may not be enough to avert catastrophic climate change. Could scrubbing carbon dioxide from the air be a viable solution? A new study by scientists at the Carnegie Institution suggests that while removing excess carbon dioxide would cool the planet, complexities of the carbon cycle would limit the effectiveness of a one-time effort. To keep carbon dioxide at low levels would require a...

The idea to sequester carbon is gaining support as a way to avoid global warming. For example, the European Union plans to invest billions of Euros within the next ten years to develop carbon capture and storage whereby CO2 will be extracted at power plants and other combustion sites and stored underground. But how effective is this procedure and what are the long-term consequences of leakage for the oceans and climate? A Niels Bohr Institute researcher has now cast light upon these issues....

Findings released during the annual Goldschmidt Conference at the University of Tennessee, Knoxville As carbon dioxide continues to burgeon in the atmosphere causing the Earth's climate to warm, scientists are trying to find ways to remove the excess gas from the atmosphere and store it where it can cause no trouble. Sigurdur Gislason of the University of Iceland has been studying the possibility of sequestration of carbon dioxide (CO2) in basalt and presented his findings today to several...

Findings released at the annual Goldschmidt Conference at the University of Tennessee, Knoxville As carbon dioxide levels in the atmosphere rise, policy makers and scientists are looking at new ways to tackle the problems associated with the greenhouse gas. One method under much discussion is carbon capture and storage (CCS), otherwise known as carbon sequestration. CCS, a newly developing technology, involves injecting carbon dioxide underground to remove it from the Earth's atmosphere....

Scientists have developed a way to detect and track carbon dioxide deep underground, giving the government an important tool that may help people find a way to keep carbon dioxide and other greenhouse gases from polluting the atmosphere. Scientists at the U.S. Department of Energy's National Energy Technology Laboratory used colorless, nontoxic liquids called perflourocarbon tracers to basically fingerprint carbon dioxide that was injected into a coal seam in northwestern New Mexico. They...

A technique originally, applied to monitor the flow of contaminants into shallow groundwater supplies, has been repurposed to monitor carbon dioxide pumped deep underground for storage. Electric Resistance Tomography (ERT) has been installed to track where a plume of injected CO_ moves underground in an oil field (Cranfield Oilfield) near Natchez, Miss. The site is part of the Southeast Regional Carbon Sequestration Partnership (SECARB), a project that eventually will store more than one...

Carbon dioxide emissions from agricultural activity in the United States can now be tracked with unprecedented resolution because of a method developed at Oak Ridge National Laboratory. A team led by Tristram West uses satellite remote sensing, computational resources and high-resolution national inventory datasets to pinpoint agricultural-based carbon emissions nationwide. The method, outlined in the journal Ecological Applications (http://www.esajournals.org/doi/full/10.1890/08-2352.1),...

Jeffrey Long's lab will soon host a round-the-clock, robotically choreographed hunt for carbon-hungry materials. The Berkeley Lab chemist leads a diverse team of scientists whose goal is to quickly discover materials that can efficiently strip carbon dioxide from a power plant's exhaust, before it leaves the smokestack and contributes to climate change. They're betting on a recently discovered class of materials called metal-organic frameworks that boast a record-shattering internal surface...
