Figure 1.

PCA of past (1960–1990) and future (2070) climates in each state (a) extracted based on 100 random GPS localities within each state and all 19 Bioclim variables at 30 arc second resolution, (b) correlation plot of 19 bioclimatic variables. Both past (1960–1990) and future (2070) climate data are from WorldClim⁸². The states of Amazonas and Rio de Janeiro have the most disparate climates now and in the future. Rondônia has little overlap with Amazonas despite being in the same biome. Rondônia and Tocantins, states at the same latitude but in different biomes, overlap some in current climate, but not in the future. In an extreme case, Tocantins shows no overlap between current and future climates. See additional details in supplement and Supplementary Table S5 for variable descriptions.
