Greenhouse gases could cause a wet Africa

Previous studies had suggested that the AHP was triggered by a ~20,000-year cyclic wobble in Earth's orbit that resulted in increased summertime heating north of the equator. That summertime heating would have warmed the land in such a way as to strengthen the monsoon winds from the ocean and enhance rainfall. Instead, the study revealed the role of two other factors: a change in Atlantic Ocean circulation that rapidly boosted rainfall in the region, and a rise in greenhouse gas concentrations that helped enhance rainfall across a wide swath of Africa.
While the industrialized world looks to reduce greenhouse gas emissions to preserve our current climate, Africa could find itself benefiting from increased emissions.
