Latest Carbon sequestration Stories
Twenty years of field studies reveal that as the Earth has gotten warmer, plants and microbes in the soil have given off more carbon dioxide. So-called soil respiration has increased about one-tenth of 1 percent per year since 1989, according to an analysis of past studies in the March 24 issue of Nature.The scientists also calculated the total amount of carbon dioxide flowing from soils, which is about 10-15 percent higher than previous measurements. That number -- about 98 petagrams of...
WASHINGTON -- A new study involving scientists from 13 different organizations, universities and research institutions states that forest protection offers one of the most effective, practical, and immediate strategies to combat climate change. The study, "Indigenous Lands, Protected Areas, and Slowing Climate Change," was published in PLoS Biology, a peer-reviewed scientific journal, and makes specific recommendations for incorporating protected areas into overall strategies to...
Morale was high and more than $1 billion was raised to fight deforestation during a one-day climate change conference held in Paris on Thursday -- a stark contrast to the disappointment and discouraging Copenhagen talks just a few months ago.After French President Nicolas Sarkozy opened the conference by describing his frustration with December 2009's United Nations (UN) emissions conference, considerable progress was made in Paris, as a 10-nation panel was established to help oversee the...
Enhanced oil recovery is a key to greater energy security, increased domestic revenues and fewer carbon emissions; "Winner States" include Arkansas, California, Indiana, Illinois, Kansas, Louisiana, Montana, New Mexico, North Dakota, Oklahoma, Texas and Wyoming. HOUSTON and WASHINGTON, March 10 /PRNewswire-USNewswire/ -- The U.S. has a significant opportunity to increase its energy independence, slash foreign oil imports by as much as half by 2030, and cut carbon emissions through a...
Curbing global climate changeCarnegie Mellon University's Edward S. Rubin will discuss U.S. energy strategies needed to mitigate global climate change Feb. 20 at the annual meeting of the American Association for the Advancement of Science (AAAS) in San Diego, Calif.Rubin, the Alumni Professor of Environmental Engineering and Science and a professor of engineering and public policy and mechanical engineering at Carnegie Mellon, will discuss the need for a climate policy that effectively puts...
Turfgrass management can create more greenhouse gas than plants remove from atmosphereDispelling the notion that urban "green" spaces help counteract greenhouse gas emissions, new research has found "“ in Southern California at least "“ that total emissions might be lower if lawns did not exist.Turfgrass lawns help remove carbon dioxide from the atmosphere through photosynthesis and store it as organic carbon in soil, making them important "carbon sinks." However, greenhouse gas emissions...
Pumping nutrient-rich water up from the deep ocean to boost algal growth in sunlit surface waters and draw carbon dioxide down from the atmosphere has been touted as a way of ameliorating global warming. However, a new study led by Professor Andreas Oschlies of the Leibniz Institute of Marine Sciences (IFM-GEOMAR) in Kiel, Germany, pours cold water on the idea."Computer simulations show that climatic benefits of the proposed geo-engineering scheme would be modest, with the potential to...
Two studies provide clearer picture of how carbon cycle was dramatically affected long agoGeoengineering -- deliberate manipulation of the Earth's climate to slow or reverse global warming -- has gained a foothold in the climate change discussion. But before effective action can be taken, the Earth's natural biogeochemical cycles must be better understood.Two Northwestern University studies, both published online recently by Nature Geoscience, contribute new -- and related -- clues as to what...
SINGAPORE, Feb. 2 /PRNewswire/ -- The carbon development market is riding high, having achieved $126 billion worth of transactions in 2008, almost double its value in 2007. By the end of the first commitment phase in 2012, countries all over the world are expected to have reduced 2.7 billion tons of carbon emissions.

Unclear land rights, corruption threaten to undermine success of promised REDD fundsAs environmental and political leaders struggle to determine how to move forward from the UN Climate Change Conference in Copenhagen, a new report by an international coalition of top forest organizations warns that the failure to set legal standards and safeguards for a mechanism to transfer funds to forest-rich nations may trigger a sharp rise in speculation and corruption, placing unprecedented pressures on...
