The concentration of methane (CH4), the most abundant organic trace gas in the atmosphere, has increased dramatically over the last few centuries, more than doubling its concentration. Increasing concentrations of methane are of special concern because of their effects on climate and atmospheric chemistry. On a per molecule basis, additional methane is much more effective as a greenhouse gas than additional CO2. Methane is also important to both tropospheric and stratospheric chemistry. Here…

The Distribution of Dissolved Methane and Its Air-Sea Flux in the Plume of a Seep Field, Lingtou Promontory, South China Sea
Methane (CH4), the most abundant hydrocarbon gas in the atmosphere, plays an important role in global climate change. Quantifying the dissolved methane and its air-sea flux from hydrocarbon seeps is…
The Relationship between the Decline of Oxygen and the Increase of Methane Gas (CH4) Emissionson the Environment Health of the Plant
TLDR
The combustion of low grade coal for the power plant activity will decrease the concentration of oxygen and increase the CH4 gas emissions in the atmosphere that can damage the health of the plants and it can even cause death.
Continuous Measurements of Greenhouse Gases and Atmospheric Oxygen in the Namib Desert
A new, near-coastal background site was established for observations of greenhouse gases (GHGs) and atmospheric oxygen in the central Namib Desert near Gobabeb, Namibia. The location of the site…
Methane : its role in climate change and options for control

Characterization model to assess ocean acidification within life cycle assessment
PurposeOcean acidification due to the absorption of increasing amounts of atmospheric carbon dioxide has become a severe problem in the recent years as more and more marine species are influenced by…
CH4 continuous measurements in the upper Spanish plateau
TLDR
The diurnal and seasonal patterns of the overall data set and background concentrations have shown that CH4 concentrations are mainly dominated by its reaction with OH radicals, and were associated to the concentrations recorded in the remaining un-disturbed sectors.
