  • Potential impact of Stratospheric Aerosol Injection on horticultural crop suitability in Africa

    Open AccessTemitope S Egbebiyi, Christopher Lennard et al.ARTICLEGeographical Journal2025References: 53

    Global warming will be devastating for agriculture in Africa, impacting food security throughout the continent. Stratospheric Aerosol Injection (SAI), which involves the injection of sulphur into the stratosphere to reduce incoming solar radiation to Earth's surface, has been proposed as a strategy to reduce the global warming rate; however, there is a knowledge gap on how this may affect horticultural crops including mango, orange and tomato in …

  • Stratospheric Aerosol Geoengineering could lower future risk of ‘Day Zero’ level droughts in Cape Town

    Open AccessRomaric C Odoulami, Mark New et al.ARTICLEEnvironmental Research Letters2020

    Anthropogenic forcing of the climate is estimated to have increased the likelihood of the 2015-2017 Western Cape drought, also called 'Day Zero' drought, by a factor of three, with a projected additional threefold increase of risk in a world with 2 C warming. Here, we assess the potential for geoengineering using stratospheric aerosols injection (SAI) to offset the risk of 'Day Zero' level droughts in a high emission future climate using climate …

  • Projected effects of 1.5 °C and 2 °C global warming levels on the intra-seasonal rainfall characteristics over the Greater Horn of Africa

    Open AccessMasilin Gudoshava, Herbert Misiani et al.ARTICLEEnvironmental Research Letters2020

    This study examines the effects of 1.5 °C and 2 °C global warming levels (GWLs) on intra-seasonal rainfall characteristics over the Greater Horn of Africa. The impacts are analysed based on the outputs of a 25-member regional multi-model ensemble from the Coordinated Regional Climate Downscaling Experiment project. The regional climate models were driven by Coupled Model Intercomparison Project Phase 5 Global Climate Models for historical and fut…

  • On the need for regional climate information over Africa under varying levels of global warming

    Open AccessChristopher Lennard, Grigory Nikulin et al.ARTICLEEnvironmental Research Letters2018

    The Paris Agreement of COP21 set a goal of holding global average temperature increases to below 2 C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5 C. This is particularly relevant for the African context where temperatures are likely to warm faster than the global average and where the magnitude of change will be regionally heterogeneous. Additionally, many biogeophysical and socioeconomic systems are …

  • The southern African climate under 1.5 °C and 2 °C of global warming as simulated by Cordex regional climate models

    Open AccessGenito Maúre, Izidine Pinto et al.ARTICLEEnvironmental Research Letters2018

    Results from an 25 regional climate model simulations from the Coordinated Regional Downscaling Experiment Africa initiative are used to assess the projected changes in temperature and precipitation over southern Africa at two global warming levels (GWLs), namely 1.5 C and 2.0 C, relative to pre-industrial values, under the Representative Concentration Pathway 8.5. The results show a robust increase in temperature compared to the control period r…

  • The effects of 1.5 and 2 degrees of global warming on Africa in the Cordex ensemble

    Open AccessGrigory Nikulin, Christopher Lennard et al.ARTICLEEnvironmental Research Letters2018

    There is a general lack of information about the potential effects of 1.5, 2 or more degrees of global warming on the regional climates within Africa, and most studies that address this use data from coarse resolution global models. Using a large ensemble of CORDEX Africa simulations, we present a pan-African overview of the effects of 1.5 and 2 C global warming levels (GWLs) on the African climate. The CORDEX simulations, consistent with their d…

  • Potential impact of 1.5 °C and 2 °C global warming on consecutive dry and wet days over West Africa

    Open AccessNana Ama Browne Klutse, Vincent O Ajayi et al.ARTICLEEnvironmental Research Letters2018

    We examine the impact of +1.5 C and +2 C global warming levels above pre-industrial levels on consecutive dry days (CDD) and consecutive wet days (CWD), two key indicators for extreme precipitation and seasonal drought. This is done using climate projections from a multi-model ensemble of 25 regional climate model (RCM) simulations. The RCMs take boundary conditions from ten global climate models (GCMs) under the RCP8.5 scenario. We define CDD as…

  • Consequences of 1.5 °C and 2 °C global warming levels for temperature and precipitation changes over Central Africa

    Open AccessWilfried M Pokam, Georges-Noel T Longandjo et al.ARTICLEEnvironmental Research Letters2018

    Discriminating climate impacts between 1.5 C and 2 C warming levels is particularly important for Central Africa, a vulnerable region where multiple biophysical, political, and socioeconomic stresses interact to constrain the region's adaptive capacity. This study uses an ensemble of 25 transient Regional Climate Model (RCM) simulations from the CORDEX initiative, forced with the Representative Concentration Pathway (RCP) 8.5, to investigate the …

  • Projected climate over the Greater Horn of Africa under 1.5 °C and 2 °C global warming

    Open AccessSarah E Osima, Victor S Indasi et al.ARTICLEEnvironmental Research Letters2018

    We analyze the potential effect of global warming levels (GWLs) of 1.5 C and 2 C above pre-industrial levels (1861-1890) on mean temperature and precipitation as well as intra-seasonal precipitation extremes over the Greater Horn of Africa. We used a large, 25-member regional climate model ensemble from the Coordinated Regional Downscaling Experiment and show that, compared to the control period of 1971-2000, annual mean near-surface temperature …
