Smithsonian scientists report new carbon dioxide study
Researchers at the Smithsonian Environmental Research Center report the results of a six-year experiment in which doubling the atmospheric greenhouse gas carbon dioxide (CO2) in a scrub oak ecosystem caused a reduction in carbon storage in the soil.   view more (2007-03-13)

Elevated CO2 in atmosphere weakens defenses of soybeans to herbivores
In research to be presented at the annual meeting of the American Society of Plant Biologists in Chicago (July 7-11, 2007), scientists will show that elevated CO2 may negatively impact the relationship between some plants and insects.   view more (2007-07-09)

Soil nutrition affects carbon sequestration in forests
On December 11, USDA Forest Service (FS) scientists from the FS Southern Research Station (SRS) unit in Research Triangle Park, NC, along with colleagues from Duke University, published two papers in The Proceedings of the National Academy of Science (PNAS) that provide a more precise understanding... view more (2006-12-14)

Hold your breath; Plants may absorb less carbon dioxide than we thought
The world's land plants will probably not be able to absorb as great a share of the rising atmospheric carbon dioxide as some models have predicted.   view more (2006-04-13)

The effects of climate change on the physiology of alfalfa
The biologist Gorka Erice Soreasu, a researcher in the Department of Plant Biology of the University of Navarra, has studied the effects of climate change on the physiology of alfalfa.   view more (2006-04-12)

Study suggests new therapy for lung disease patients
A new study by researchers at Northwestern University's Feinberg School of Medicine may change current thinking about how best to treat patients in respiratory distress in hospital intensive care units.   view more (2008-02-11)

Elevated Carbon Dioxide Changes Soil Microbe Mix Below Plants
A detailed analysis of soil samples taken from a forest ecosystem with artificially elevated levels of atmospheric carbon dioxide (CO2) reveals distinct changes in the mix of microorganisms living in the soil below trembling aspen.   view more (2007-12-20)

Grasslands won't help buffer climate change as carbon dioxide levels rise
Because grasslands and forests operate in complex feedback loops with both the atmosphere and soil, understanding how ecosystems respond to global changes in climate and element cycling is critical to predicting the range of global environmental changes-and attendant ecosystem responses-likely to... view more (2005-08-09)

Prepare CO2 capture and storage now for greater environmental benefit later
CO2 capture and storage can make a major contribution to CO2 reduction in the Netherlands. By the mid-21st century 80 to 110 million tonnes of CO2 per year could be avoided in the sectors energy, industry and transport. This is half of the current CO2 emission. Moreover, this can be realised... view more (2007-04-16)

Unexpected growth in atmospheric CO2
A team of scientists has found that atmospheric carbon dioxide (CO2) growth has increased 35 percent faster than expected since 2000. The findings are published this week in the journal Proceedings of the National Academy of Sciences (PNAS).   view more (2007-10-23)

Global changes alter plant growth schedule
Any gardener knows that different plant species mature at different times. Scientists studying natural plant communities know this phenomenon allows species to co-exist by reducing overlap so there is less competition for limited resources.   view more (2006-09-05)

CO2 storage in coal can be predicted better
CO2 storage in the ground is being considered increasingly more often in order to realise the climate and energy objectives. Dutch researcher Saikat Mazumder made it possible to better predict routes of the 'underground highways' along which gasses like carbon dioxide (CO2) and methane (CH4) will... view more (2007-04-16)

A dash of lime -- a new twist that may cut CO2 levels back to pre-industrial levels
Scientists say they have found a workable way of reducing CO2 levels in the atmosphere by adding lime to seawater. And they think it has the potential to dramatically reverse CO2 accumulation in the atmosphere, reports Cath O'Driscoll in SCI's Chemistry & Industry magazine published today.    view more (2008-07-21)

Experiment suggests limitations to carbon dioxide 'tree banking'
While 10 years of bathing North Carolina pine tree stands with extra carbon dioxide did allow the trees to grow more tissue, only those pines receiving the most water and nutrients were able to store significant amounts of carbon that could offset the effects of global warming, scientists told a... view more (2007-08-07)

Insects take a bigger bite out of plants in a higher CO2 world
Atmospheric carbon dioxide levels are rising at an alarming rate, and new research indicates that soybean plant defenses go down as CO2 goes up. Elevated CO2 impairs a key component of the plant's defenses against leaf-eating insects, according to the report.   view more (2008-03-25)

US faces burning emissions issue
Severe United States wildfires can contribute as much as vehicles to carbon emissions in some US states, although the amount is highly variable.   view more (2007-11-01)

Decline in uptake of carbon emissions confirmed
A decline in the proportion of carbon dioxide (CO2) emissions absorbed by land and oceans is speeding up the growth of atmospheric CO2, according to a paper published today in the US Journal: Proceedings of the National Academy of Science.   view more (2007-10-25)

Carbon dioxide triggers inborn distress
PLoS ONE publishes a study showing that inhalation of carbon dioxide (CO2) triggers emotional distress and a panic response in healthy individuals. The findings of the study posit panic as an inborn survival-oriented response. The results may be relevant for a better understanding and the further... view more (2007-10-03)

Technological breakthrough in the fight to cut greenhouse gases
Scientists at Newcastle University have pioneered breakthrough technology in the fight to cut greenhouse gases.   view more (2008-04-25)

Study Finds Plenty of Carbon Dioxide Storage Capacity Underground in Kentucky
As concern has grown over the effects of the human release of carbon dioxide (CO2) gas into the atmosphere, so too has research into technologies to manage CO2.   view more (2006-10-09)

Greenhouse gas effect consistent over 420 million years
New calculations show that sensitivity of Earth's climate to changes in the greenhouse gas carbon dioxide (CO2) has been consistent for the last 420 million years, according to an article in Nature by geologists at Yale and Wesleyan Universities.   view more (2007-03-29)

Well-informed citizens consider CO2 storage to be acceptable
When energy is generated from fossil fuels, the greenhouse gases produced contribute to climate change. By capturing the CO2 produced and storing it underground, a major objection to the use of fossil fuels can be overcome.   view more (2006-04-19)

North Atlantic slows on the uptake of CO2
Further evidence for the decline of the oceans' historical role as an important sink for atmospheric carbon dioxide is supplied by new research by environmental scientists from the University of East Anglia.   view more (2007-10-23)

Carbon turns over much faster through basal food-chain levels in aquatic than in terrestrial ecosystems
Global temperatures have increased dramatically over the past century, which is causing major impacts on climate patterns, ocean circulation and wildlife preservation. The increase in temperature is largely due to a rise of anthropogenic emissions of greenhouse gases, of which CO2 is one of the... view more (2004-02-25)

CO2 emissions could violate EPA ocean-quality standards within decades
In a commentary in the September 25, 2007, issue of the Geophysical Research Letters (GRL), a large team of scientists state that human-induced carbon dioxide (CO2) emissions will alter ocean chemistry to the point where it will violate U.S. Environmental Protection Agency Quality Criteria [1976]... view more (2007-09-20)
