Woods Hole Research Center scientist furthering discussion of soil carbon decomposition
Significantly more carbon is stored in the world's soils than is present in the atmosphere. In a process called a "positive feedback," global warming may stimulate decomposition of soil organic matter, thus releasing heat-trapping carbon dioxide gas to the atmosphere, possibly causing the rate of global warming to increase further.   view more (2006-03-09)

Fire is important part of global climate change, report scientists
Fire must be accounted for as an integral part of climate change, according to 22 authors of an article published in the April 24 issue of the journal Science. The authors determined that intentional deforestation fires alone contribute up to one-fifth of the human-caused increase in emissions of carbon dioxide, a heat-trapping gas that raises... view more...

Global warming of the future is projected by ancient carbon emissions
Global warming 55 million years ago suggests a high climate sensitivity to carbon dioxide, according to research led by Mark Pagani, associate professor of geology and geophysics at Yale and published in the December 8 issue of Science.   view more (2006-12-08)

Tropical forests — Earth's air conditioner
Planting and protecting trees—which trap and absorb carbon dioxide as they grow—can help to remove carbon dioxide from the atmosphere.   view more (2007-04-10)

Northern forests less effective than tropical forests in reducing global warming
Forests in the United States and other northern mid- and upper-latitude regions are playing a smaller role in offsetting global warming than previously thought, according to a study appearing in this week's issue of Science.   view more (2007-06-25)

Trees to offset the carbon footprint?
How effective are new trees in offsetting the carbon footprint? A new study suggests that the location of the new trees is an important factor when considering such carbon offset projects. Planting and preserving forests in the tropics is more likely to slow down global warming.   view more (2007-04-10)

IGBP calls for better observation of Earth's "Achilles' heels"
Monitoring the most sensitive "hotspots" of the Earth is an important way of assessing the health of our planet and predicting our future, said IGBP (International Geosphere-Biosphere Programme) scientists speaking at the Earth Observation Summit in Washington last week. The summit was attended by officials from more than 30 countries... view more... (2003-08-06)

Geoengineering could slow down the global water cycle
As fossil fuel emissions continue to climb, reducing the amount of sunlight hitting the Earth would definitely have a cooling effect on surface temperatures.   view more (2008-05-28)

Researchers discover trees in Amazon much older than assumed, raising questions on global climate impact of region
Trees in the Amazon tropical forests are old. Really old, in fact, which comes as a surprise to a team of American and Brazilian researchers studying tree growth in the world's largest tropical region.   view more (2005-12-14)

Rising surface ozone reduces plant growth and adds to global warming
Scientists from three leading UK research institutes have today released new findings that could have major implications for food production and global warming in the 21st century.   view more (2007-07-26)

Global warming: Our best guess is likely wrong
No one knows exactly how much Earth's climate will warm due to carbon emissions, but a new study this week suggests scientists' best predictions about global warming might be incorrect.   view more (2009-07-15)

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 most important. To understand the capacity of... view more...

Complex carbon picture clearer
Study shows that more plant litter resulting from higher CO2 could boost the amount of carbon released into the atmosphere.   view more (2007-12-12)

Greenhouse gas/temperature feedback mechanism may raise warming beyond previous estimates
A team of European scientists reports that climate change estimates for the next century may have substantially underestimated the potential magnitude of global warming.   view more (2006-05-22)

Hungry microbes share out the carbon in the roots of plants
Sugars made by plants are rapidly used by microbes living in their roots, according to new research at the University of York, creating a short cut in the carbon cycle that is vital to life on earth.   view more (2007-10-19)

Adding up renewable energy
Do the overall efficiencies of renewable energy sources, such as wind, solar, and geothermal add up in terms of their complete life cycle from materials sourcing, manufacture, running, and decommissioning" Researchers in Greece have carried out a life cycle assessment to find the answer.   view more (2007-08-14)

Nature can help reduce greenhouse gas, but only to a point
Plants apparently do much less than previously thought to counteract global warming, according to a paper to be published in next week's online edition of Proceedings of the National Academy of Sciences.   view more (2006-04-11)

ESA tests laser to measure atmospheric carbon dioxide
A recent ESA campaign has demonstrated how a technique using lasers could be employed to measure carbon dioxide in the atmosphere. The campaign supports one of the main objectives of the candidate Earth Explorer A-SCOPE mission.   view more (2008-12-04)

New earth observation centres announced
Two new centres which will use satellites and models to help forecast earthquakes and the effects of carbon in climate change were announced (Wednesday 17 October) by Lord Sainsbury, Science & Innovation Minister. Said Lord Sainsbury, " I am delighted to announce that the Natural Environment Research Council is establishing two new... view more... (2001-10-19)

Plants' role in global warming re-examined in ORNL Science paper
Estimates of increased plant respiration in response to higher global temperatures may be somewhat overstated as they have not taken into account plants' ability to adjust to changing conditions, according to researchers from Oak Ridge National Laboratory.   view more (2006-05-02)
