2015b). Depending on the future socioeconomic scenario, this could increase global inequality and leave some African countries poorer than at present . Inequalities between African countries are projected to widen under climate change, with negative impacts estimated to be largest in west and east Africa . While negative impacts across African economies are highly likely under climate change, precise magnitudes are debated in the literature. Alternative statistical analyses suggest a 12% reduction of GDP per capita by 2100 under RCP8.5 across African countries relative to a future without climate change , while computable general equilibrium models generate smaller damages as well, ranging from 3.8% reduction across sub-Saharan Africa in 2060 under warming of 2.5℃  to 12% across all of Africa in 2100 under warming of 5℃  .
