Agricultural methane emissions and the potential formitigation [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2021
Agriculture is the largest anthropogenic source of methane (CH4), emitting 145 Tg CH4 y−1to the atmosphere in 2017. The main sources are enteric fermentation, manure management, rice cultivation and residue burning. There is significant potential to reduce CH4from these sources, with bottom-up mitigation potentials of approximately 10.6, 10, 2 and 1 Tg

Retrieval of methane source strengths in Europe using a simple modeling approach to assess the potential of spaceborne lidar observations [PDF]

Atmospheric Chemistry and Physics, 2014
We investigate the sensitivity of future spaceborne lidar measurements to changes in surface methane emissions. We use surface methane observations from nine European ground stations and a Lagrangian transport model to infer surface methane emissions for

Large emissions from floodplain trees close the Amazon methane budget [PDF]

, 2017
Wetlands are the largest global source of atmospheric methane (CH4), a potent greenhouse gas. However, methane emission inventories from the Amazon floodplain, the largest natural geographic source of CH4 in the tropics, consistently underestimate the ...

Effects of Chemical Feedbacks on Decadal Methane Emissions Estimates [PDF]

, 2020
The coupled chemistry of methane, carbon monoxide (CO), and hydroxyl radical (OH) can modulate methane's 9‐year lifetime. This is often ignored in methane flux inversions, and the impacts of neglecting interactive chemistry have not been quantified ...

The role of endophytic methane-oxidizing bacteria in submerged Sphagnum in determining methane emissions of Northeastern Siberian tundra [PDF]

Biogeosciences, 2011
The role of the microbial processes governing methane emissions from tundra ecosystems is receiving increasing attention. Recently, cooperation between methanotrophic bacteria and submerged Sphagnum was shown to reduce methane emissions but also to ...

Water table level controls methanogenic and methanotrophic communities and methane emissions in a Sphagnum-dominated peatland

Microbiology Spectrum, 2023
Peatlands are important sources of the greenhouse gas methane emissions equipoised by methanogens and methanotrophs. However, knowledge about how microbial functional groups associated with methane production and oxidation respond to water table ...
