Significance Methane, the second most important greenhouse gas, has varied markedly in its atmospheric growth rate. The cause of these fluctuations remains poorly understood. Recent efforts to determine the drivers of the pause in growth in 1999 and renewed growth from 2007 onward have focused primarily on changes in sources alone. Here, we show that changes in the major methane sink, the hydroxyl radical, have likely played a substantial role in the global methane growth rate. This work has…

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

Modulation of hydroxyl variability by ENSO in the absence of external forcing

It is found that natural OH variability can produce (unforced) methane trends as large as the observed changes in methane over the last few decades and that ENSO is the dominant mode of OH variability, with the modulation of OH occurring primarily through lightning NOx.

Chemical Feedback From Decreasing Carbon Monoxide Emissions

Understanding changes in the burden and growth rate of atmospheric methane (CH4) has been the focus of several recent studies but still lacks scientific consensus. Here we investigate the role of

Interpreting contemporary trends in atmospheric methane

It is shown that net-zero cost emission reductions can lead to a declining atmospheric burden, but can take three decades to stabilize.

Variability in Atmospheric Methane From Fossil Fuel and Microbial Sources Over the Last Three Decades

Atmospheric measurements show an increase in CH4 from the 1980s to 1998 followed by a period of near‐zero growth until 2007. However, from 2007, CH4 has increased again. Understanding the variability

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

Effects of Chemical Feedbacks on Decadal Methane Emissions Estimates

The coupled chemistry of methane, carbon monoxide (CO), and hydroxyl radical (OH) can modulate methane's 9‐year lifetime. This is often ignored in methane flux inversions, and the impacts of

Anthropogenic emission is the main contributor to the rise of atmospheric methane during 1993–2017

Abstract Atmospheric methane (CH4) concentrations have shown a puzzling resumption in growth since 2007 following a period of stabilization from 2000 to 2006. Multiple hypotheses have been proposed

Methane and Global Environmental Change

Global atmospheric methane concentrations have continued to rise in recent years, having already more than doubled since the Industrial Revolution. Further environmental change, especially climate

On the role of trend and variability in the hydroxyl radical (OH) in the global methane budget

Abstract. Decadal trends and interannual variations in the hydroxyl radical (OH), while poorly constrained at present, are critical for understanding the observed evolution of atmospheric methane



Renewed growth of atmospheric methane

Following almost a decade with little change in global atmospheric methane mole fraction, we present measurements from the Advanced Global Atmospheric Gases Experiment (AGAGE) and the Australian

Three decades of global methane sources and sinks

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

Role of OH variability in the stalling of the global atmospheric CH4 growth rate from 1999 to 2006

Abstract. The growth in atmospheric methane (CH4) concentrations over the past 2 decades has shown large variability on a timescale of several years. Prior to 1999 the globally averaged CH4

Rising atmospheric methane: 2007–2014 growth and isotopic shift

From 2007 to 2013, the globally averaged mole fraction of methane in the atmosphere increased by 5.7 ± 1.2 ppb yr−1. Simultaneously, δ13CCH4 (a measure of the 13C/12C isotope ratio in methane) has

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.

Evidence for Substantial Variations of Atmospheric Hydroxyl Radicals in the Past Two Decades

Global measurements of 1,1,1-trichloroethane (CH3CCl3, methyl chloroform) provide an accurate method for determining the global and hemispheric behavior of OH, and show variations that imply important and unexpected gaps in current understanding of the capability of the atmosphere to cleanse itself.

The trend in atmospheric methane δ13C and implications for isotopic constraints on the global methane budget

A recent paper by Tans [1997] has drawn attention to the isotopic disequilibrium that inevitably prevails when atmospheric methane is not in steady state with its sources, noting in particular the

Evidence for variability of atmospheric hydroxyl radicals over the past quarter century

The hydroxyl free radical (OH) is the major oxidizing chemical in the atmosphere, destroying about 3.7 petagrams (Pg) of trace gases each year, including many gases involved in ozone depletion, the
