  • 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…

  • A holistic assessment framework for marine carbon dioxide removal options

    Open AccessChristian Baatz, Lukas Tank et al.ARTICLEEnvironmental Research Letters2025

    Marine carbon dioxide removal (mCDR) options could potentially play an important role in future CDR policy portfolios. They include, for example, ocean alkalinity enhancement, blue carbon projects such as mangrove cultivation, as well as sub-seabed storage of captured atmospheric CO 2 . In this paper we present a novel assessment framework designed for mCDR options. The framework provides important conceptual advancements to existing frameworks c…

  • Learning increases both acceptability and scrutiny of carbon dioxide removal methods: Quasi-experimental evidence

    Open AccessFelix Dörpmund, David Reiner et al.ARTICLEEnvironmental Research Letters2025

    Carbon dioxide removal (CDR) technologies are increasingly recognized as necessary complements to decarbonization efforts; however, public acceptance remains a critical implementation challenge. This study investigates the impact of educational exposure on perceptions of CDR methods among individuals with a pre-existing interest in climate solutions. We conducted a quasi-experimental study with pre- and post-surveys of participants ( n = 366 pre-…

    Open AccessPierre Friedlingstein, Mike O’Sullivan et al.ARTICLEEarth System Science Data2023

    Accurate assessment of anthropogenic carbon dioxide (CO2) emissions and their redistribution among the atmosphere, ocean, and terrestrial biosphere in a changing climate is critical to better understand the global carbon cycle, support the development of climate policies, and project future climate change. Here we describe and synthesize data sets and methodology to quantify the five major components of the global carbon budget and their uncertai…

  • The drivers and impacts of Amazon forest degradation

    Open AccessDavid M Lapola, Patricia Pinho et al.ARTICLEScience2023

    Approximately 2.5 × 10 6 square kilometers of the Amazon forest are currently degraded by fire, edge effects, timber extraction, and/or extreme drought, representing 38% of all remaining forests in the region. Carbon emissions from this degradation total up to 0.2 petagrams of carbon per year (Pg C year −1 ), which is equivalent to, if not greater than, the emissions from Amazon deforestation (0.06 to 0.21 Pg C year −1 ). Amazon forest degradatio…

  • Neglected implications of land-use and land-cover changes on the climate-health nexus

    Open AccessAnton Orlov, Kristin Aunan et al.ARTICLEEnvironmental Research Letters2023

    Climate change can substantially affect temperature-related mortality and morbidity, especially under high green-house gas emission pathways. Achieving the Paris Agreement goals require not only drastic reductions in fossil fuel-based emissions but also land-use and land-cover changes (LULCC), such as reforestation and afforestation. LULCC has been mainly analysed in the context of land-based mitigation and food security. However, growing scienti…

  • Differences in land-based mitigation estimates reconciled by separating natural and land-use CO2 fluxes at the country level

    Open AccessClemens Schwingshackl, Wolfgang A Obermeier et al.ARTICLEOne Earth2022

    Anthropogenic and natural CO2 fluxes on land constitute substantial CO2 emissions and removals but are usually not well distinguished in national greenhouse gas reporting. Instead, countries frequently combine natural and indirect human-induced CO2 fluxes on managed land in their reports, which diminishes their usefulness for designing policies consistent with climate mitigation targets. Here, we separate natural and land-use-related CO2 fluxes f…

  • Land-use change emissions based on high-resolution activity data substantially lower than previously estimated

    Open AccessRaphael Ganzenmüller, Selma Bultan et al.ARTICLEEnvironmental Research Letters2022

    Land-use and land-cover changes (LULCCs) contributed around one third to the cumulative, anthropogenic CO 2 emissions from 1850 to 2019. Despite its great importance, estimates of the net CO 2 fluxes from LULCC (E LUC ) have high uncertainties, compared to other components of the global carbon cycle. One major source of uncertainty roots in the underlying LULCC forcing data. In this study, we implemented a new high-resolution LULCC dataset (HILDA…

  • Reconstruction of historical forest cover on a 1° grid in central and southeast Europe from AD 1800 to 2000

    Open AccessXue Zheng, Xiuqi Fang et al.ARTICLEThe Holocene2022References: 5

    The natural vegetation has been substantially changed over the last millenium, especially from forest to agricultural areas in Europe. To study the effects of deforestation on carbon and climate system, it is essential to construct spatially precise maps in forest cover. The current representative historical forest data sets are either derivatives of agricultural datasets or are produced based on the deforestation-population relationship. Almost …

  • A review of trends and drivers of greenhouse gas emissions by sector from 1990 to 2018

    Open AccessWilliam F Lamb, Thomas Wiedmann et al.ARTICLEEnvironmental Research Letters2021

    Global greenhouse gas (GHG) emissions can be traced to five economic sectors: energy, industry, buildings, transport and AFOLU (agriculture, forestry and other land uses). In this topical review, we synthesise the literature to explain recent trends in global and regional emissions in each of these sectors. To contextualise our review, we present estimates of GHG emissions trends by sector from 1990 to 2018, describing the major sources of emissi…

  • Global and regional drivers of land-use emissions in 1961–2017

    Open AccessChaopeng Hong, Jennifer A Burney et al.ARTICLENature2021

  • A multi-data assessment of land use and land cover emissions from Brazil during 2000–2019

    Open AccessThais M Rosan, Kees Klein Goldewijk et al.ARTICLEEnvironmental Research Letters2021

    Brazil is currently the largest contributor of land use and land cover change (LULCC) carbon dioxide net emissions worldwide, representing 17%–29% of the global total. There is, however, a lack of agreement among different methodologies on the magnitude and trends in LULCC emissions and their geographic distribution. Here we perform an evaluation of LULCC datasets for Brazil, including those used in the annual global carbon budget (GCB), and nati…

  • 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…

  • Five years of variability in the global carbon cycle: Comparing an estimate from the Orbiting Carbon Observatory-2 and process-based models

    Open AccessZichong Chen, D N Huntzinger et al.ARTICLEEnvironmental Research Letters2021

    Year-to-year variability in CO 2 fluxes can yield insight into climate-carbon cycle relationships, a fundamental yet uncertain aspect of the terrestrial carbon cycle. In this study, we use global observations from NASA’s Orbiting Carbon Observatory-2 (OCO-2) satellite for years 2015–2019 and a geostatistical inverse model to evaluate 5 years of interannual variability (IAV) in CO 2 fluxes and its relationships with environmental drivers. OCO-2 la…

  • Soil carbon sequestration simulated in CMIP6-Lumip models: Implications for climatic mitigation

    Open AccessAkihiko Ito, Tomohiro Hajima et al.ARTICLEEnvironmental Research Letters2020

    Land-use change affects both the quality and quantity of soil organic carbon (SOC) and leads to changes in ecosystem functions such as productivity and environmental regulation. Future changes in SOC are, however, highly uncertain owing to its heterogeneity and complexity. In this study, we analyzed the outputs of simulations of SOC stock by Earth system models (ESMs), most of which are participants in the Land-Use Model Intercomparison Project. …
