The atmospheric methane trend is not fully understood. Here we investigate the role of the
main sink, the main natural source, and anthropogenic emissions on the methane growth …

The global atmospheric methane growth rates reported by NOAA for 2020 and 2021 are the
largest since systematic measurements began in 1983. To explore the underlying reasons …

The tropics is the nexus for many of the remaining gaps in our knowledge of environmental
science, including the carbon cycle and atmospheric chemistry, with dire consequences for …

Surface observations have recorded large and incompletely understood changes to
atmospheric methane (CH4) this century. However, their ability to reveal the responsible …

Methane (CH4) is a potent greenhouse gas with a warming potential 84 times that of carbon
dioxide (CO2) over a 20‐year period. Atmospheric CH4 concentrations have been rising …

Key challenges to regionalization of methane fluxes in the Amazon basin are the large
seasonal variation in inundated areas and habitats, the wide variety of aquatic ecosystems …

Extensive floodplains throughout the Amazon basin support important ecosystem services
and influence global water and carbon cycles. A recent change in the hydroclimatic regime …

The amount of methane released to the atmosphere from the Nord Stream subsea pipeline
leaks remains uncertain, as reflected in a wide range of estimates,,,,,,,,,,,,,,,,–. A lack of …

We use the GEOS-Chem global 3-D model and two inverse methods (the maximum a
posteriori and ensemble Kalman filter) to infer regional methane (CH4) emissions and the …
