What do we know about the global methane budget? Results from four decades of atmospheric CH4 observations and the way forward
Atmospheric CH4 is arguably the most interesting of the anthropogenically influenced, long-
lived greenhouse gases. It has a diverse suite of sources, each presenting its own …

Short-Lived Climate Forcers (Chapter 6)
Short‑lived climate forcers (SLCFs) affect climate and are, in most cases, also air pollutants.
They include aerosols (sulphate, nitrate, ammonium, carbonaceous aerosols, mineral dust …

[HTML][HTML] Estimating emissions of methane consistent with atmospheric measurements of methane and C of methane
We have constructed an atmospheric inversion framework based on TM5-4DVAR to jointly
assimilate measurements of methane and δ 13 C of methane in order to estimate source …

Rising methane: A new climate challenge
SEM Fletcher, H Schaefer - Science, 2019 - science.org
In 2007, the amount of methane in the atmosphere (CH4) began to rise after a 7-year period
of near-zero growth (1). Recent research shows that a second step change occurred in 2014 …
