Table S1. The area and current (1981-2010) climate information including annual average of minimum temperature and total annual precipitation of each refuge.
Table S2. The number of links of each refuge node based on climate directions. The number of ”depart” refers to the number of other refuge nodes where a target refuge node’s current-climate space will be found. The number of ”arrive” means the number of other refuge nodes where their current-climate spaces will occur in a target node for the time period indicated.
Table S3. The climate categories of each refuge under each climate scenario for the time period indicated. Five climate categories are represented using five colors (red: disappearing climates; orange: isolating climates, yellow: dispersing climates, light green: enduring climates, green: climate hubs).
