  • Degrees of reversibility of ocean deoxygenation in an atmospheric carbon dioxide removal scenario

    Open AccessEstela A Monteiro, David P Keller et al.ARTICLEEnvironmental Research Letters2025

    Over the last century, increasing atmospheric carbon dioxide (CO 2 ) concentrations, among other greenhouse gases, and resulting climate change have greatly impacted the ocean. Observed impacts include lower oxygen solubility and changes in ocean stratification, circulation and biological activity. To reduce the carbon burden in the atmosphere in the future and thereby mitigate anthropogenic climate change, carbon dioxide removal (CDR) techniques…

  • Global Carbon Budget 2021

    Open AccessPierre Friedlingstein, Matthew W Jones 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 datasets and methodology toquantify the five major components of the global carbon budget and theiruncertainties. …

  • CO 2 fertilization of crops offsets yield losses due to future surface ozone damage and climate change

    Open AccessFelix Leung, Stephen Sitch et al.ARTICLEEnvironmental Research Letters2022

    Tropospheric ozone (O 3 ) is harmful to plant productivity and negatively impacts crop yields. O 3 concentrations are projected to decrease globally in the optimistic Representative Concentration Pathway of 2.6 W m –2 (RCP2.6) but increase globally following the high-emission scenario under the RCP8.5, with substantial implications for global food security. The damaging effect of O 3 on future crop yield is affected by CO 2 fertilization and clim…

  • Nitrogen cycle impacts on CO 2 fertilisation and climate forcing of land carbon stores

    Open AccessChris Huntingford, Eleanor Burke et al.ARTICLEEnvironmental Research Letters2022

    Anthropogenic fossil fuel burning increases atmospheric carbon dioxide (CO 2 ) concentration, which is adjusting the climate system. The direct impact of rising CO 2 levels and climate feedback alters the terrestrial carbon stores. Land stores are presently increasing, offsetting a substantial fraction of CO 2 emissions. Less understood is how this human-induced carbon cycle perturbation interacts with other terrestrial biogeochemical cycles. The…

  • 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…

  • 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…

  • Significant feedbacks of wetland methane release on climate change and the causes of their uncertainty

    Open AccessNicola Gedney, Chris Huntingford et al.ARTICLEEnvironmental Research Letters2019

    Emissions from wetlands are the single largest source of the atmospheric greenhouse gas (GHG) methane (CH 4 ). This may increase in a warming climate, leading to a positive feedback on climate change. For the first time, we extend interactive wetland CH 4 emissions schemes to include the recently quantified, significant process of CH 4 transfer through tropical trees. We constrain the parameterisations using a multi-site flux study, and biogeoche…

  • Simulating the Earth system response to negative emissions

    Open AccessChris Jones, Chris D Jones et al.ARTICLEEnvironmental Research Letters2016

    Natural carbon sinks currently absorb approximately half of the anthropogenic CO2 emitted by fossilfuel burning, cement production and land-use change. However, this airborne fraction may change inthe future depending on the emissions scenario. An important issue in developing carbon budgets toachieve climate stabilisation targets is the behaviour of natural carbon sinks, particularly under lowemissions mitigation scenarios as required to meet th…

  • Implications of climate change for agricultural productivity in the early twenty-first century

    Open AccessJemma Gornall, Richard Betts et al.ARTICLEPhilosophical Transactions of the…2010

    This paper reviews recent literature concerning a wide range of processes through which climate change could potentially impact global-scale agricultural productivity, and presents projections of changes in relevant meteorological, hydrological and plant physiological quantities from a climate model ensemble to illustrate key areas of uncertainty. Few global-scale assessments have been carried out, and these are limited in their ability to captur…
