The objective of this work is to make a current environmental assessment of Brazil and its projection for 2070, with an emissions scenario that will continue to increase throughout the 21st century. Based on the maps of types of bioclimatic regimes in Brazil, its current situation and its situation for an RCP 8.5 scenario for the year 2070 are established according to the CCSM4 climate change model of the Fifth Assessment Report of the IPCC in 2014. The regimes are related current bioclimatics with the main ecoregions existing in Brazil: Amazonia, Cerrado and Caatinga. With the Global Forest Wacht platform, the deforestation processes in this country and their causes are shown, as well as the period of high intensity fires in September 2024. Finally, based on current biolimatic data, the changes in the Amazon are shown, the closed and the Caatinga.
