Climate modelers speculatively suggest that this reduction in solar radiation at the surface may have led to the failure of the monsoon in sub-Saharan Africa during the 1970s and 1980s, together with the associated famines such as the Sahel drought, caused by Northern hemisphere pollution cooling the Atlantic.
Os modelos climáticos suxiren especulativamente que esta redución de luz solar na superficie pode conducir á falta de monzóns en África subsahariana durante os anos 1970 e os 80, xunto coas crises por fame asociadas, causadas porque a contaminación do Hemisferio Norte arrefriaba o Atlántico.
