Researchers create more accurate model greenhouse gases from peatlands
Posted by PhyOrg: None Given on October 3rd, 2014
PhyOrg: Scientists at the U.S. Department of Energy's Argonne National Laboratory have created a new model to more accurately describe the greenhouse gases likely to be released from Arctic peatlands as they warm. Their findings, based on modeling how oxygen filters through soil, suggest that previous models probably underestimated methane emissions and overrepresented carbon dioxide emissions from these regions.
Peatlands, common in the Arctic, are wetlands filled with dead and decaying organic matter....

Preserve the services of mangroves – Earth’s invaluable coastal forests, experts urge
Posted by PhyOrg: None Given on November 15th, 2012
PhyOrg: Found mostly in the tropics straddling the land and sea, mangroves make up less than half of one percent of forests of all kinds worldwide. Taken together, some 70 species of mangroves are found in 123 tropical and sub-tropical nations and territories but occupy just 152,000 square km in total -- an area slightly larger than Nepal. Experts are urging policy makers to preserve mangroves and their essential services to nature and humanity alike, saying their replacement with shrimp farms and other...
