adeforestation. Atmospheric concentrations of methane (CH4) have more than doubled over the past two centuries. These and other GHG increases have led to a 0.6° C growth in the global average surface temperature since 1900. If current emission trends are not altered, global temperatures are exp...

The movement of methane (CH4) from anaerobic sediments through the leaves, stems, and flowers of aquatic plants and into the atmosphere was found to provide a significant pathway for the emission of CH4 from the aquatic substrates of flooded wetlands. Methane concentrations well above the surroundin...
cesses cancel each other to give a region of ozone insensitivity to added NO x . Following Crutzen’s sequential analysis and using chemistry from the 1974 Lawrence Livermore National Laboratory (LLNL) one-dimensional atmospheric model and the Gear routine on the methane reaction sequences, Johnston...
The Global Methane Cycle: Isotopes and Mixing Ratios, Sources and Sinks The increase of the atmospheric methane concentration over the past 200 years, and by 1% per year since 1978, reaching 1.7 ppmv in 1990 is underlined... O Bréas,C Guillou,F Reniero,... - 《Isotopes in Environmental...
Ice cores methane reconstructions are believed to reflect atmospheric CH_4 concentration fluctuation with time and to reveal the past changes in terrestrial methane emissions. It has been proposed that the past natural CH_4 fluctuations were mainly due to changes in the source strength, through varia...
Moreover, the spatial approach study undertaken, standing out the fine-grained mosaic of the atmospheric composition close to the ground, could be of a specific interest for the validation of remote-sensing approaches to emissions budgets. The Ebre River Delta site is fund by the ClimaDat ...
