For the middle (2035–2060) and end (2075–2100) of the 21st century mean ensemble of Regional Climate Model version 4 simulations for the Representative Concentration Pathway 8.5 scenario are presented. The global-coupled models of Coupled Model Intercomparison Project Phase 5 drive the members for the period 1970–2100 using different physics configurations. The delta change approach is applied to filter out the bias of the model simulation. Notable changes of the K–T climates are found in SA, mainly in Brazil. Replacement of tropical wet-dry (Aw) by dry semiarid (Bs) occurs over Northeast Brazil (NEB). Reduction of tropical humid (Ar) and an increase of Aw is projected in the North Brazil and Amazon. Retreat of subtropical humid (Cr) replaced by Aw is found in the Southeast Brazil. An increase of subtropical winter-dry (Cw) and decrease Cr is noted in Argentina and in Paraguay Cr is replaced by Ar. In the south of SA, a retreat of subarctic oceanic (Eo) and an increase of temperate oceanic (Do) and dry arid (Bw) occur. In general, the projected changes of K–T climate types in the 21st century over SA show a tendency for a drier climate.427-434engclimate classificationregional climate changeSouth AmericaArtigo10.1002/asl.785Acesso aberto2-s2.0-850340065812-s2.0-85034006581.pdf
