  abstract = {{I}n this study, we investigate changes in temperature and precipitation extremes over {W}est and {C}entral {A}frica (hereafter, {WAF} domain) as a function of global mean temperature with a focus on the implications of global warming of 1.5 degrees {C} and 2 degrees {C} according the {P}aris {A}greement. {W}e applied a scaling approach to capture changes in climate extremes with increase in global mean temperature in several subregions within the {WAF} domain: {W}estern {S}ahel, {C}entral {S}ahel, {E}astern {S}ahel, {G}uinea {C}oast and {C}entral {A}frica including {C}ongo {B}asin. {W}hile there are several uncertainties and large ensemble spread in the projections of temperature and precipitation indices, most models show high-impact changes in climate extremes at subregional scale. {A}t these smaller scales, temperature increases within the {WAF} domain are projected to be higher than the global mean temperature increase (at 1.5 degrees {C} and at 2 degrees {C}) and heat waves are expected to be more frequent and of longer duration. {T}he most intense warming is observed over the drier regions of the {S}ahel, in the central {S}ahel and particularly in the eastern {S}ahel, where the precipitation and the soil moisture anomalies have the highest probability of projected increase at a global warming of 1.5 degrees {C}. {O}ver the wetter regions of the {G}uinea {C}oast and {C}entral {A}frica, models project a weak change in total precipitation and a decrease of the length of wet spells, while these two regions have the highest increase of heavy rainfall in the {WAF} domain at a global warming of 1.5 degrees {C}. {W}estern {S}ahel is projected by 80% of the models to experience the strongest drying with a significant increase in the length of dry spells and a decrease in the standardized precipitation evapotranspiration index. {T}his study suggests that the 'dry gets drier, wet gets wetter' paradigm is not valid within the {WAF} domain.},
