Climate disruptions following a nuclear conflict would substantially affect food security, putting large parts of mankind at risk of starvation as has been shown by climate-crop modelling studies. Yet, earlier studies did not integrate comprehensive uncertainties in crop models across various intensities of climate perturbations from different levels of atmospheric soot injection, the potentials and limitations of adaptation such as timing of growing seasons or crop choice, and further disruptions in agricultural production such as fertilizer and labor shortages. Herein, we propose a project that will set out to address these research gaps by harnessing the comprehensive crop modelling capacities of the Global Gridded Crop Model Intercomparison (GGCMI) ensemble to simulate secondary climatic impacts of nuclear conflict on global crop production at various levels of stratospheric soot injection for the above adaptation options and extended impacts. This will provide the thus far most comprehensive assessment of potential impacts on crop production and the available option space for adaptation under the working hypotheses that adaptation potential is limited and supply chain disruptions may substantially exacerbate impacts already at lower intensities of soot injection.
