R code and datasets to support "Stability and changes of global climate diversity by 2100"

After you download and unzip the '.rar' file, it contains three subfolders. The files included in each subfolder and their descriptions are as follows: For the folder named 'code-R':All our R code is stored in the 'code-R' folder, which contains 11 R code files. You should first run the files 'step1-1-function-for-cd-dist.R' and 'step1-2-function-for-cd-combine-zones.R'. Next, run 'step1-3-cd-calculate.R'—in this code, you need to set the path for the supporting data files according to your own directory structure. After completing these steps, please run the step2-related code and step3-related code in sequence to generate the plots. For the folder named 'data':We saved the scaled PCA factors for the five global regions (Extended Data Fig. 9 in the article) at a 2-arcminute resolution in the subfolder named 'p2_pca_scl'. This subfolder contains three '.tif' format files, which are the stacked raster files for the current period, SSP126 scenario, and SSP585 scenario, respectively. The climate diversity results for each of the eight moving windows are saved in the folder named 'p6_disc_merge' for each region. The folder named 'p6_disc_zones_txt' stores the processing files. For the folder named 'stat-csv':We saved the statistical results used for plotting in this folder.
