Methane is an important greenhouse gas, responsible for about 20% of the warming induced by long-lived greenhouse gases since pre-industrial times. By reacting with hydroxyl radicals, methane reduces the oxidizing capacity of the atmosphere and generates ozone in the troposphere. Although most sources and sinks of methane have been identified, their relative contributions to atmospheric methane levels are highly uncertain. As such, the factors responsible for the observed stabilization of… 

Investigation of the global methane budget over 1980–2017 using GFDL-AM4.1

Abstract. Changes in atmospheric methane abundance have implications for both chemistry and climate as methane is both a strong greenhouse gas and an important precursor for tropospheric ozone. A

The Drivers of Atmospheric Methane Fluctuations over the Last Three Decades

Understanding the processes behind the observed methane fluctuations over the last three decades is crucial for reliable projections of future levels of atmospheric methane, the second most important

Half of global methane emissions come from highly variable aquatic ecosystem sources

Atmospheric methane is a potent greenhouse gas that plays a major role in controlling the Earth’s climate. The causes of the renewed increase of methane concentration since 2007 are uncertain given

The Global Methane Budget 2000–2017

Abstract. Understanding and quantifying the global methane (CH4) budget is important for assessing realistic pathways to mitigate climate change. Atmospheric emissions and concentrations of CH4

A 21st-century shift from fossil-fuel to biogenic methane emissions indicated by 13CH4

The atmospheric methane level has resumed its increase after a plateau between 1999 and 2006, and a box-model analysis suggests that diminishing thermogenic emissions, probably from the fossil-fuel industry, and/or variations in the hydroxyl CH4 sink caused the plateau.

The terrestrial biosphere as a net source of greenhouse gases to the atmosphere

The cumulative warming capacity of concurrent biogenic methane and nitrous oxide emissions is a factor of about two larger than the cooling effect resulting from the global land carbon dioxide uptake from 2001 to 2010, which results in a net positive cumulative impact of the three greenhouse gases on the planetary energy budget.

Observing the carbon-climate system

Increases in atmospheric CO2 and CH4 result from a combination of forcing from anthropogenic emissions and Earth System feedbacks that reduce or amplify the effects of those emissions on atmospheric

Sources of variability in short-lived climate pollutants and their effect on climate

Targeting short-lived climate pollutants (SLCPs) such as methane (CH4), tropospheric ozone (O3) and atmospheric aerosols has been proposed as an effective method of reducing the rate of near-term

Non-CO 2 Greenhouse Gases

In the past decades, accurate and precise atmospheric measurements of radiatively active gases have been crucial in revealing the rapid and unceasing growth of their global concentrations that has

Atmospheric methane isotopic record favors fossil sources flat in 1980s and 1990s with recent increase

There is strong evidence that methane emissions from fossil fuel sectors were approximately constant in the 1980s and 1990s but increased significantly between 2000 and 2009, and this finding challenges recent conclusions based on atmospheric ethane that fugitive fossil fuel emissions fell during much of this period.



Contribution of anthropogenic and natural sources to atmospheric methane variability

The results indicate that wetland emissions dominated the inter-annual variability of methane sources, whereas fire emissions played a smaller role, except during the 1997–1998 El Niño event.

Methane emissions from terrestrial plants under aerobic conditions

It is demonstrated using stable carbon isotopes that methane is readily formed in situ in terrestrial plants under oxic conditions by a hitherto unrecognized process, suggesting that this newly identified source may have important implications for the global methane budget and may call for a reconsideration of the role of natural methane sources in past climate change.

Long-term decline of global atmospheric ethane concentrations and implications for methane

It is shown that global ethane emission rates decreased from 14.3 to 11.3 teragrams per year, or by 21 per cent, from 1984 to 2010, and suggested that reduced fugitive fossil fuel emissions account for at least 10–21 teragramS per year of the decrease in methane's global emissions, significantly contributing to methane’s slowing atmospheric growth rate since the mid-1980s.

Large-Scale Controls of Methanogenesis Inferred from Methane and Gravity Spaceborne Data

A combination of satellite data, which indicate water table depth and surface temperature, and atmospheric methane concentrations are used to determine the location and strength of methane emissions from wetlands, the largest natural global source, and tropical and higher-latitude CH4 variations are largely described by Γ and TS variations, respectively.

Biogeochemical aspects of atmospheric methane

Methane is the most abundant organic chemical in Earth's atmosphere, and its concentration is increasing with time, as a variety of independent measurements have shown. Photochemical reactions

Continuing decline in the growth rate of the atmospheric methane burden

The global atmospheric methane burden has more than doubled since pre-industrial times,, and this increase is responsible for about 20% of the estimated change in direct radiative forcing due to

Three‐dimensional model synthesis of the global methane cycle

The geographic and seasonal emission distributions of the major sources and sinks of atmospheric methane were compiled using methane flux measurements and energy and agricultural statistics in

Constraining global methane emissions and uptake by ecosystems

Abstract. Natural methane (CH4) emissions from wet ecosystems are an important part of today's global CH4 budget. Climate affects the exchange of CH4 between ecosystems and the atmosphere by

Global atmospheric methane: budget, changes and dangers

Improved constraints on the global CH4 budget and its break down of emissions by source sector and country will come from an enhanced observation network for CH4 abundance and its isotopic composition (δ13C, δD (D=2H and δ14C).

Interpreting methane variations in the past two decades using measurements of CH 4 mixing ratio and isotopic composition

Abstract. The availability δ13C-CH4 measurements from atmospheric samples has significantly improved in recent years, which allows the construction of time series spanning up to about 2 decades. We
