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)


Too little nitrogen may restrain plants'€™ carbon storage capability, U of M paper shows
Plants' ability to absorb increased levels of carbon dioxide in the air may have been overestimated, a new University of Minnesota study shows. View News Article (2012-10-03)


Carbon dioxide's new-found signalling role could be applied to blood flow, birth and deafness
New research reveals exactly how the body measures carbon dioxide and suggests that far from being a metabolic waste product, it could play a key role as a biological signalling molecule. View News Article (2013-11-13)


Global warming predictions are overestimated, suggests study on black carbon
A detailed analysis of black carbon -- the residue of burned organic matter -- in computer climate models suggests that those models may be overestimating global warming predictions. View News Article (2008-11-20)


Ocean acidification may contribute to global shellfish decline
Relatively minor increases in ocean acidity brought about by high levels of carbon dioxide have significant detrimental effects on the growth, development, and survival of hard clams, bay scallops, and Eastern oysters, according to researchers at Stony Brook University's School of Marine and Atmospheric Sciences. View News Article (2009-10-27)


Global warming plus natural bacteria could release vast carbon deposits currently stored in Arctic soil
Increasing concentrations of carbon dioxide in the atmosphere will make global temperatures rise. By studying soil cores from the Arctic, scientists have discovered that this rise in temperature stimulates the growth of microorganisms that can break down long-term stores of carbon, releasing them into the atmosphere as carbon dioxide. This will lead to further increases in global temperatures. View News Article (2005-05-05)
