The number of Africans leaving their home country to move to other parts of the globe is expected to more than double in upcoming years, with climate change acting as a main accelerator of this expected migration. Although an imminent mass exodus is not expected, new findings do show the real-life effects of changing weather patterns.

A European Commission report aimed to identify past and present migration patterns in Africa and use these models to predict how future migration may look. Results revealed that although the number of Africans leaving their country of birth for long periods of time or for good is currently about 1.4 million a year, by 2050 this number is expected to reach between 2.8 million to 3.5 million a year.
