With reducing carbon emissions on the national agenda, a group of expert panelists will discuss methods, markets, testing and policy issues on how carbon sinks or carbon sequestration may be used to reduce atmospheric CO2.
Carbon sequestration is the process through which carbon dioxide (CO2) from the atmosphere is absorbed by trees, plants and crops through photosynthesis, and stored as carbon in biomass (tree trunks, branches, foliage and roots) and soils. The term "sinks" is also used to refer to forests, croplands, and grazing lands, and their ability to sequester carbon. Agriculture and forestry activities can also release CO2 to the atmosphere. So, a carbon sink occurs when carbon sequestration is greater than carbon releases over some time period.
The keynote symposium, "Carbon Sequestration: Methods, Markets and Policy," includes presentations by six experts. The symposium is being held on Wednesday, 8 Oct from 3:00 to 5:10 pm in the General Assembly Theater Hall C of the George R. Brown Convention Center, Houston, TX, as part of the 2008 Joint Annual Meeting of five scientific societies.
According to a National Academy of Sciences 2001 report, "Greenhouse gases are accumulating in the Earth's atmosphere as a result of human activities, causing surface air temperatures and subsurface ocean temperatures to rise."
In addition to temperature, human-induced climate change may also affect growing seasons, precipitation and the frequency and severity of extreme weather events, such as fire. These changes can influence forests, farming and the health of ecosystems, and thus carbon sequestration.
Speakers at this session will environmental controls on the soil carbon cycle; forest carbon sequestration; testing commercial-scale geologic carbon sequestration; issues with ocean carbon sequestration; and legal and regulatory challenges facing carbon sequestration:
Ronald Amundson will discuss how nearly 20% of anthropogenic CO2 emissions are from land-use changes, but reducing this loss requires understanding the natural and management-specific impacts on soil carbon. The main control on the soil carbon cycle is climate. Radiocarbon measurements have shown that decomposition accelerates with increasing temperature and that under projected warming scenarios soils should release CO2 and provide a positive feedback to warming.
Richard Birdsey will discuss how U.S. forests currently offset about 15% of emissions of CO2 from fossil fuels and how this baseline rate could be doubled or more through activities including avoided deforestation, afforestation, improved forest management, and substitution of wood for other materials.
Brian McPherson will discuss a project designing and deploying several pilot tests to validate the most promising CO2 sequestration technologies and infrastructure concepts, including a major deep saline sequestration demonstration.
Haroon Kheshgi will discuss how a range of ocean carbon sequestration concepts are compared to other options including other forms of carbon sequestration.
Putting aside the technical and engineering aspects of carbon capture and sequestration, Allison D. Wood will discuss how legal and policy issues need to be addressed with regard to the issue.
The symposium will be moderated by Jerry Hatfield, USDA-Agricultural Research Service and Past-President, American Society of Agronomy.
More than 8,000 scientists and professionals will gather at the George R. Brown Convention Center in Houston, 5 to 9 October to discuss the latest research and trends in energy, water resources, climate change, agriculture, science education, and more. This is the first-ever Joint Annual Meeting of the Geological Society of America, Soil Science Society of America, American Society of Agronomy, Crop Science Society of America, and Gulf Coast Association of Geological Societies.

The Geological Society of America (GSA), founded in 1888, is a broad, unifying scientific society with 21,000 members from academia, government, and industry in more than 85 countries. Through its meetings, publications, and programs, GSA enhances the professional growth of its members, and promotes the geosciences in the service of humankind. Headquartered in Boulder, Colorado, GSA encourages cooperative research among earth, life, planetary, and social scientists, fosters public dialogue on geoscience issues, and supports all levels of earth science education.
ASA (www.agronomy.org), CSSA (www.crops.org) and SSSA (www.soils.org) are scientific societies based in Madison, WI, helping their 11,000+ members advance the disciplines and practices of agronomy, crop, and soil sciences by supporting professional growth and science policy initiatives, and by providing quality, research-based publications and a variety of member services.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
