Better way to calculate greenhouse gas value of ecosystems (June 6, 2010) -- Researchers have developed a new, more accurate method of calculating the change in greenhouse gas emissions that results from changes in land use. The new approach takes into account many factors not included in previous methods, such as the ecosystem's ability to take up or release greenhouse gases over time and all of the greenhouse gases absorbed and released in the process of introducing new crops. The researchers calculated the greenhouse gas value of a variety of ecosystem types. ... > full story
