Atmospheric Methane: Comparison Between Methane's Record in 2006–2022 and During Glacial Terminations Open

E. G. Nisbet, Martin Manning, E. J. Dlugokencky, Sylvia Michel, Xin Lan , et al. · 2025

Atmospheric methane's rapid growth from late 2006 is unprecedented in the observational record. Assessment of atmospheric methane data attributes a large fraction of this atmospheric growth to increased natural emissions over the tropics, …

Methane’s record rise 2020-2023: likely causes, impacts and consequences Open

Martin Manning, Euan G. Nisbet, Sylvia Michel, Xin Lan, E. J. Dlugokencky , et al. · 2024

From 2020, the atmospheric methane burden has grown at the fastest rate in the detailed observational record. This rise has been accompanied by an unprecedented plunge in d13C(CH4). The causes of recent accelerated growth are as yet uncert…

Atmospheric Methane: Comparison Between Methane's Record in 2006–2022 and During Glacial Terminations Open

Euan G. Nisbet, Martin Manning, E. J. Dlugokencky, Sylvia Michel, Xin Lan , et al. · 2023

Is the current methane growth event comparable to a glacial/interglacial Termination event? Open

Euan G. Nisbet, Martin Manning, David Lowry, Rebecca Fisher, James L. France · 2023

Atmospheric methane shows very sharp growth since 2006. Growing evidence for methane's main sink, atmospheric OH, being relatively stable implies a major increase in methane emissions is occurring. Methane's synchronous isotopic shift to m…

Atmospheric methane: Comparison between methane’s record in 2006-2022 and during glacial terminations. Open

Euan G. Nisbet, Martin Manning, Edward J. Dlugokencky, Sylvia Michel, Xin Lan , et al. · 2023

Atmospheric methane’s rapid growth from 2006 to the present is unprecedented in the observational record. Isotopic evidence implies the growth is mainly driven by an increase in biogenically-sourced emissions, both from wetlands and rumina…

Abstract. We have constructed an atmospheric inversion framework based on TM5 4DVAR to jointly assimilate measurements of methane and δ¹³C of methane in order to estimate source-specific methane emissio…

RADIOCARBON AND ATMOSPHERIC<sup>14</sup>CO<sub>2</sub>PIONEER ATHOL RAFTER Open

Jocelyn Turnbull, Dave Lowe, Martin Manning, Rodger Sparks · 2021

Direct atmospheric 14 CO 2 measurements began in New Zealand in 1954, initially to improve 14 C as a dating tool, but quickly evolving into a method for understanding the carbon cycle. These early 14 CO 2 measurements immediately demonstra…

Atmospheric methane and nitrous oxide: challenges alongthe path to Net Zero Open

Euan G. Nisbet, Edward J. Dlugokencky, Rebecca Fisher, James L. France, David Lowry , et al. · 2021

The causes of methane's renewed rise since 2007, accelerated growth from 2014 and record rise in 2020, concurrent with an isotopic shift to values more depleted in 13 C, remain poorly understood. This rise is the dominant departure from gr…

Methane Mitigation: Methods to Reduce Emissions, on the Path to the Paris Agreement Open

Euan G. Nisbet, Rebecca Fisher, David Lowry, James L. France, Grant Allen , et al. · 2020

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 Agreement. Urgent action is required to bring methane back to a pa…

Advancing Scientific Understanding of the Global Methane Budget in Support of the Paris Agreement Open

Anita L. Ganesan, Stefan Schwietzke, Benjamin Poulter, Tim Arnold, Xin Lan , et al. · 2019

The 2015 Paris Agreement of the United Nations Framework Convention on Climate Change aims to keep global average temperature increases well below 2 °C of preindustrial levels in the Year 2100. Vital to its success is achieving a decrease …

Very Strong Atmospheric Methane Growth in the 4 Years 2014–2017: Implications for the Paris Agreement Open

Euan G. Nisbet, Martin Manning, E. J. Dlugokencky, Rebecca Fisher, David Lowry , et al. · 2019

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 since the 1980s. The increase in the methane burden began in 2…

Rising atmospheric methane: 2007–2014 growth and isotopic shift Open

Euan G. Nisbet, E. J. Dlugokencky, Martin Manning, David Lowry, Rebecca Fisher , et al. · 2016

From 2007 to 2013, the globally averaged mole fraction of methane in the atmosphere increased by 5.7 ± 1.2 ppb yr −1 . Simultaneously, δ 13 C CH4 (a measure of the 13 C/ 12 C isotope ratio in methane) has shifted to significantly more nega…

Cows, Sheep and Science: A Scientific Perspective on Biological Emissions from Agriculture Open

Michele Hollis, Cecile A. M. de Klein, David J. Frame, Mike Harvey, Martin Manning , et al. · 2016

Biological emissions from agriculture (methane and nitrous oxide) make up almost half New Zealand’s total greenhouse gas emissions, so their importance relative to carbon dioxide is of particular policy interest. Motu Economic and Public P…
