Fossil fuel emissions will complicate radiocarbon dating, warns scientist
Fossil fuel emissions could soon make it impossible for radiocarbon dating to distinguish new materials from artefacts that are hundreds of years old. View News Article (2015-07-21)

Cover crops can sequester soil organic carbon
A 12-year University of Illinois study shows that, although the use of cover crops does not improve crop yields, the practice does increase the amount of sequestered soil organic carbon using three different soil management systems.  View News Article (2014-12-03)

Researchers make breakthrough in the production of double-walled carbon nanotubes
In recent years, the possible applications for double-walled carbon nanotubes have excited scientists and engineers, particularly those working on developing renewable energy technologies. View News Article (2008-12-23)

Tiny levels of carbon monoxide damage fetal brain
A UCLA study has discovered that chronic exposure during pregnancy to miniscule levels of carbon monoxide damages the cells of the fetal brain, resulting in permanent impairment. View News Article (2009-06-25)

Past spikes in carbon dioxide levels accompanied by high ocean circulation
Two abrupt rises in carbon dioxide and Northern Hemispheric warming occurred during the last glacial ice melt, and new evidence confirms that these spikes were accompanied by deep ocean "flushing" events.  View News Article (2015-09-25)

Model predicts shifts in carbon absorption by forest canopies
An Agricultural Research Service (ARS) scientist participated in a project to fine-tune computer models that can indicate when forest "carbon sinks" become net carbon generators instead. View News Article (2010-04-01)

World's forests role in carbon storage immense, profound
Until now, scientists were uncertain about how much and where in the world terrestrial carbon is being stored. In the July 14 issue of Science Express, scientists report that, between 1990 and 2007, the world's forests stored about 2.4 gigatons of carbon per year.  View News Article (2011-07-18)

Increased tropical forest growth could release carbon from the soil
A new study shows that as climate change enhances tree growth in tropical forests, the resulting increase in litterfall could stimulate soil micro-organisms leading to a release of stored soil carbon.  View News Article (2011-08-15)

First-ever 'State of the Carbon Cycle Report' finds troubling imbalance
The first "State of the Carbon Cycle Report" for North America, released online this week by the U.S. Climate Change Science Program, finds the continent's carbon budget increasingly overwhelmed by human-caused emissions. View News Article (2007-11-15)

A link between greenhouse gases and the evolution of C4 grasses
How a changing climate can affect ecosystems is an important and timely question, especially considering the recent global rise in greenhouse gases. View News Article (2007-12-21)
