CO2, methane and nitrous oxide have a varying influence on the climate. Accordingly, CH4 and N2O contribute greatly to the greenhouse effect despite their comparatively low atmospheric concentration. To be able to compare the climate impact of greenhouse gases and define their warming potential, metha...

A small climate-amplifying effect of climate-carbon cycle feedback ArticleOpen access19 May 2021 Introduction Methane is the second most important anthropogenic greenhouse gas (GHG) associated with climate change. The atmospheric concentration of methane was relatively stable in the early-2000s but resu...
including those reported for upland temperate forested soils (α = 1.018–1.022)39,40and tropical forested soils (1.012–1.023)41, but were within range of both subtropical wetlands (α = 1.003–1.032)24,42and rice paddies (α = 1.013–1.033)43,44(Supplementary Table2). Our l...
“Rising temperatures increase microbial activity and vegetation growth,” Zhu continues, “which are associated with emissions of gasses like methane. By understanding how natural sources of methane are changing, we can more accurately monitor greenhouse gasses that inform scientists about the current an...
A relevant advantage is the low cost of both methane and carbon dioxide that would be transformed into high-value-added products [7], thus decreasing their emissions and impact on the greenhouse effect [15]. Additionally, the reaction represents a very convenient energy transfer system [16]....
The photocatalytic transformation of methane and carbon dioxide into syngas via DRM is a promising route for not only converting solar energy to chemical energy but also mitigating the greenhouse effect by catalytic conversion (Equation 14).(Equation 14)CH4 + CO2→ 2H2 + 2CO, ΔG0298K = 171...
An apparent reason for this is DRM’s ability to consume two major greenhouse gases (CO2 and CH4) to produce syngas, from which cleaner fuels via Fisher-Tropsch [1] and value-added chemicals [2] are synthesized. However, a major obstacle towards the large-scale commercialization of this ...
How Bad of a Greenhouse Gas Is Methane? The global warming potential of the gaseous fossil fuel may be consistently underestimated ByGayathri Vaidyanathan&ClimateWire At present, nations report methane emissions in terms of CO2 equivalents, using GWP100 as the conversion factor. This allows nations,...
Aquatic ecosystems are globally significant sources of the greenhouse gas methane to the atmosphere. Until recently, methane production was thought to be a strictly anaerobic process confined primarily to anoxic sediments. However, supersaturation of met
