The map of precipitation differences shows an increase of 20 mm/year in Mali and Niger for a total of 300 mm under present climate conditions. This amount increases when moving southwards and reaches 150 mm in Nigeria and 200 mm in Guinea. These two regions receive more than 2000 mm every year in present climate. This precipitation increases are further heightened with +3°C global warming.
Details and further information:
This table shows that the precipitation increases occur mainly in late summer.
The climate change indicators have been calculated from the CNRM/CNRM-ARPEGE52, CNRM/ENEA-REGCM, ECEARTH/CSC-REMO, ECEARTH/SMHI-RCA4, ECEARTH/DMI-HIRHAM, MPI-ES/CSC-REMO simulations.
