Paul. Because some types of soil microbes consume methane, they may prevent plant-produced methane from reaching the atmosphere. Field tests will be needed to assess the plant’s influence, she notes.To test whether plants are a source of methane, the scientists created ___. A. a oxygen...
The terrestrial wetlands have been reported to act as a source and sink for atmospheric CH 4 . Therefore, recent concerns about CH 4 emission from terrestrial wetlands could be addressed properly because it is one of the major causes in contributing the status of CH 4 in the environment....
The natural wetlands of the Tibetan Plateau (TP) are considered to be an important natural source of methane (CH4) to the atmosphere. The long-term variation in CH4 associated with climate change and wetland loss is still largely unknown. From 1950 to 2010, CH4 emissions over the TP were ...
Methane Emissions from Natural Wetlands in the United States: Satellite-Derived Estimation Based on Ecosystem Carbon Cycling Wetlands are an important natural source of methane to the atmosphere. The amounts of methane emitted from inundated ecosystems in the United States can va... C Potter,S Kloo...
Researchers found that methane concentrations in the air above Los Angeles fluctuate in tandem with the seasons. In winter, when natural gas use is at its highest, methane concentrations are also highest. In summer, when natural gas use drops, so does the amount of methane in the air. ...

Field experiments showed that this natural wetland acts as a CH4 sink in spring (30 1000 g/m2.h), a strong source in summer (4003000 g/m2.h) and a weak source in autumn (< 400 g/m2.h). Reed plants play an important role in transportation and emission of methane produced in soil....

basis (IPCC, 2013). Methane has an effectiveatmospheric lifetimeof approximately 12 years while a large portion of CO2emissions persists in the atmosphere for much longer. Therefore, the climate impact of methane is greater in the short term with a 20-yearglobal warming potential(GWP) of 84 ...
Although methane hydrate accumulations are located in difficult environments and present numerous technical challenges, they are widely distributed and the largest source of hydrocarbons on Earth. A variety of technologies could be developed to produce them using pressure reduction, ion exchange, and othe...
