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 …

A factor of 2.5 increase in the global abundance of atmospheric methane (CH4) since 1750
contributes 0.5 Wm− 2 to total direct radiative forcing by long-lived greenhouse gases (2.77 …

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 …

Wetlands are the largest global source of atmospheric methane (CH4), a potent greenhouse
gas. However, methane emission inventories from the Amazon floodplain,, the largest …

Given that anthropogenic greenhouse gas (GHG) emissions must be immediately reduced
to avoid drastic increases in global temperature, methane emissions have been placed …

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 …

Characterizing and attributing methane (CH 4) emissions across varying scales are
important from environmental, safety, and economic perspectives and are essential for …

Atmospheric methane (CH 4) continues to increase, but there are multiple anthropogenic
source categories that can be targeted for cost-effective emissions reduction. Cities emit CH …

We put forward a general conceptual model of CO 2 behaviour in the vadose zone of karst
aquifers, based on physical principles of air flow through porous media and caves …

Recent studies have suggested that CH4 emissions in Los Angeles and other large cities
may be underestimated. We utilized stable isotopes (13C and D) and radiocarbon (14C) to …
