Based on the results of the historical experiment of the CMIP5 and CMIP6 projects, the effectiveness of the scenario estimates (RCP/SSP1 2.6, RCP/SSP2 4.5 and RCP/SSP5 8.5) of the future air temperature for Central Africa for the IPSL and BCC global climate models is evaluated and the simulation results of these projects are compared with each other and with the observations of meteorological stations in the region, both for the historical experimental period and with the observations of recent years for the implementation of future climate projections.
