Reports on Risk Assessment, Economic Viability Fulfill Agency's Act 129 Requirements HARRISBURG, Pa., May 13 /PRNewswire-USNewswire/ -- The Department of Conservation and Natural Resources today posted two reports online that conclude that with the appropriate changes in laws, Pennsylvania's geology could store carbon dioxide in a cost-competitive and manageable way. Creating such a system would bring with it jobs and a cleaner environment, but it cannot be accomplished without substantive...

What happens to the soil when you remove the plants? Crop residues, perennial warm season grasses, and short-rotation woody crops are potential biomass sources for cellulosic ethanol production. While most research is focused on the conversion of cellulosic feedstocks into ethanol and increasing production of biomass, the impacts of growing energy crops and the removal of crop residue on soil and environmental quality have received less attention. Moreover, effects of crop residue removal on...

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. The results will help pinpoint the effectiveness of trees in offsetting carbon releases that contribute to higher atmospheric temperatures and global climate change. ARS plant physiologist Erik Hamerlynck teamed up with Rutgers University biologist Karina Schafer and U.S. Forest Service colleagues Kenneth...

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 reduce...

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 change Carnegie 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...

Turfgrass management can create more greenhouse gas than plants remove from atmosphere Dispelling 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...

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...
