Methane emissions in the Arctic are important, and may be contributing to global warming. While methane emission rates from Arctic lakes are well documented, methods are needed to quantify the relative contribution of active layer groundwater to the overall lake methane budget. Here we report measurements of natural tracers of soil/groundwater, radon, and radium, along with methane concentratio...

An Agricultural Sector Model is used to determine the economic potential of agricultural greenhouse gas emission reduction strategies within hypothetical emission mitigation markets. For a complete set of agricultural land management decisions, emissions and emission reductions of carbon dioxide, methane, and nitrous oxide are accounted for and simultaneously subjected to a wide range of carbon...

landfill gas is generated by organic waste decomposing under anaerobic conditions. landfill gas contributes to the emission in the atmosphere of greenhouse gases and causing global warming. humidity of environment is an effective parameter on rate of gas generation in landfills. saravan landfill is investigated as study area in this research. it located in 20 kilometers of rasht-tehran highway....
