  • Forestation in CMIP6: Wide model spread in tree cover and land carbon uptake

    Open AccessSabine Egerer, David M Lawrence et al.ARTICLEEnvironmental Research Letters2025

    Forestation is expected to play an significant role as a terrestrial carbon dioxide removal technology in low-emission scenarios by storing carbon in the biosphere, thereby changing the physical properties of the land surface. To represent land use change, including afforestation and reforestation (AR), Earth system models (ESM) that contribute to the Coupled Model Intercomparison Project Phase 6 (CMIP6) draw on common projected land use data fro…

  • Global Carbon Budget 2022

    Open AccessPierre Friedlingstein, Mike O’Sullivan et al.ARTICLEEarth System Science Data2022

    Accurate assessment of anthropogenic carbon dioxide (CO2) emissions andtheir redistribution among the atmosphere, ocean, and terrestrial biospherein a changing climate is critical to better understand the global carboncycle, support the development of climate policies, and project futureclimate change. Here we describe and synthesize data sets and methodologies toquantify the five major components of the global carbon budget and theiruncertaintie…

  • Dynamic global vegetation models underestimate net CO 2 flux mean and inter-annual variability in dryland ecosystems

    Open AccessNatasha MacBean, Russell L Scott et al.ARTICLEEnvironmental Research Letters2021

    Despite their sparse vegetation, dryland regions exert a huge influence over global biogeochemical cycles because they cover more than 40% of the world surface (Schimel 2010 Science 327 418–9). It is thought that drylands dominate the inter-annual variability (IAV) and long-term trend in the global carbon (C) cycle (Poulter et al 2014 Nature 509 600–3, Ahlstrom et al 2015 Science 348 895–9, Zhang et al 2018 Glob. Change Biol . 24 3954–68). Projec…

  • The Global Methane Budget 2000–2017

    Open AccessMarielle Saunois, Ann R Stavert et al.ARTICLEEarth System Science Data2020

    Understanding and quantifying the global methane (CH4) budget is important for assessing realistic pathways to mitigate climate change. Atmospheric emissions and concentrations of CH4 continue to increase, making CH4 the second most important human-influenced greenhouse gas in terms of climate forcing, after carbon dioxide (CO2). The relative importance of CH4 compared to CO2 depends on its shorter atmospheric lifetime, stronger warming potential…

  • Uncertainty in carbon budget estimates due to internal climate variability

    Open AccessKatarzyna Tokarska, Vivek K Arora et al.ARTICLEEnvironmental Research Letters2020

    Remaining carbon budget specifies the cap on global cumulative CO2 emissions from the present-day onwards that would be in line with limiting global warming to a specific maximum level. In the context of the Paris Agreement, global warming is usually interpreted as the externally-forced response to anthropogenic activities and emissions, but it excludes the natural fluctuations of the climate system known as internal variability. A remaining carb…

    Open AccessCorinne Le Quéré, Robbie M Andrew et al.ARTICLEEarth System Science Data2018

    Accurate assessment of anthropogenic carbon dioxide(CO2) emissions and their redistribution among the atmosphere,ocean, and terrestrial biosphere – the “global carbon budget” – isimportant to better understand the global carbon cycle, support thedevelopment of climate policies, and project future climate change. Here wedescribe data sets and methodology to quantify the five major components ofthe global carbon budget and their uncertainties. Foss…

  • The influence of non-CO 2 forcings on cumulative carbon emissions budgets

    Open AccessKatarzyna Tokarska, Nathan P Gillett et al.ARTICLEEnvironmental Research Letters2018

    Carbon budgets provide a useful tool for policymakers to help meet the global climate targets, as they specify total allowable carbon emissions consistent with limiting warming to a given temperature threshold. Non-CO2 forcings have a net warming effect in the Representative Concentration Pathways (RCP) scenarios, leading to reductions in remaining carbon budgets based on CO2 forcing alone. Carbon budgets consistent with limiting warming to below…

  • Global wetland contribution to 2000–2012 atmospheric methane growth rate dynamics

    Open AccessBenjamin Poulter, Philippe Bousquet et al.ARTICLEEnvironmental Research Letters2017

    Increasing atmospheric methane (CH 4 ) concentrations have contributed to approximately 20% of anthropogenic climate change. Despite the importance of CH 4 as a greenhouse gas, its atmospheric growth rate and dynamics over the past two decades, which include a stabilization period (1999–2006), followed by renewed growth starting in 2007, remain poorly understood. We provide an updated estimate of CH 4 emissions from wetlands, the largest natural …
