Understanding and quantifying the global methane (CH 4) budget is important for assessing
realistic pathways to mitigate climate change. Atmospheric emissions and concentrations of …

The atmospheric methane burden is increasing rapidly, contrary to pathways compatible
with the goals of the 2015 United Nations Framework Convention on Climate Change Paris …

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 …

ES 6: 3-5 Replace “It is unequivocal that emissions of the well-mixed greenhouse gases
(GHG) carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2 O) from human activities …

Executive summary Land and climate interact in complex ways through changes in forcing
and multiple biophysical and biogeochemical feedbacks across different spatial and …

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 …

Atmospheric methane grew very rapidly in 2014 (12.7±0.5 ppb/year), 2015 (10.1±0.7
ppb/year), 2016 (7.0±0.7 ppb/year), and 2017 (7.7±0.7 ppb/year), at rates not observed …

Methane (CH4) is produced in many natural systems that are vulnerable to change under a
warming climate, yet current CH4 budgets, as well as future shifts in CH4 emissions, have …

Atmospheric methane plays a major role in controlling climate, yet contemporary methane
trends (1982–2017) have defied explanation with numerous, often conflicting, hypotheses …

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 …
