With increased GHG emissions, mean temperature is projected to increase over the whole continent, as are temperature extremes over most of the continent . Increased mean annual rainfall is projected over the eastern Sahel, eastern east Africa and central Africa . In contrast, reduced mean annual rainfall and increased drought  are projected over southwestern southern Africa and coastal north Africa, with drought in part as a result of increasing atmospheric evaporative demand due to higher temperatures . The frequency and intensity of heavy precipitation are projected to increase across most of Africa, except northern and southwestern Africa .
