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...

Having a large-scale boreal forest biomass inventory would allow scientists to understand better the carbon cycle and to predict more accurately Earth's future climate. However, obtaining these maps has been wrought with difficulty "“ until now. A new processing algorithm has been developed using stacks of images from the Advanced Synthetic Aperture Radar (ASAR) on ESA's Envisat satellite that allows for the retrieval of boreal forest biomass well beyond the levels that have been...

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...

Such burns release less carbon dioxide than wildfires, scientists find The use of prescribed burns to manage western forests may help the United States reduce its carbon footprint. Results of a new study find that such burns, often used by forest managers to reduce underbrush and protect bigger trees, release substantially less carbon dioxide emissions than wildfires of the same size. "It appears that prescribed burns can be an important piece of a climate change strategy," says Christine...

Seventy-five per cent of the world's heather moorlands are in the UK. However, pollution, overgrazing and wild fires have damaged large areas. Several organizations in the Peak District National Park are trying to restore and conserve the moorland habitat. As part of the Festival of Social Science organized by the Economic and Social Research Council (12-21 March 2010), the Peak District National Park Authority in Partnership with the National Trust and Moors for the Future is running a walk...

MIAMI, March 2 /PRNewswire-USNewswire/ -- An international coalition today thanked the nine U.S. Senators who sponsored the Clean Energy Partnerships Act for advancing marine conservation as part of the solution to climate change. The Act is focused on mitigating climate change and making the transition to a clean energy economy, through offsetting greenhouse gas emissions. The legislation advances marine conservation by including the restoration and conservation of certain coastal and...

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...

CORVALLIS, Ore. "“ A recent study at Oregon State University indicates that some past approaches to calculating the impacts of forest fires have grossly overestimated the number of live trees that burn up and the amount of carbon dioxide released into the atmosphere as a result. The research was done on the Metolius River Watershed in the central Oregon Cascade Range, where about one-third "“ or 100,000 acres "“ of the area burned in four large fires in 2002-03. Although...

Weizmann Institute scientists show that in one kind of forest, its 'energy budget' includes significant reserves of heat The simple formula we've learned in recent years "“ forests remove the greenhouse gas CO2 from the atmosphere; therefore forests prevent global warming "“ may not be quite as simple as we thought. Forests can directly absorb and retain heat, and, in at least one type of forest, these effects may be strong enough to cancel out a good part of the benefit in...
