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

Tip** elements are components of the Earth system which may respond nonlinearly to
anthropogenic climate change by transitioning toward substantially different long‐term …

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 …

1. Methods We use the same data and approaches to estimate CH 4 emissions as in
Saunois et al (2020). One approach we use is a top-down (TD) ensemble of 11 inversions …

The permafrost zone is expected to be a substantial carbon source to the atmosphere, yet
large-scale models currently only simulate gradual changes in seasonally thawed soil …

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 …

Atmospheric methane (CH4) is a potent greenhouse gas, and its mole fraction has more
than doubled since the preindustrial era. Fossil fuel extraction and use are among the …

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 …

The Younger Dryas (YD), arguably the most widely studied millennial-scale extreme climate
event, was characterized by diverse hydroclimate shifts globally and severe cooling at high …
