The margin is calculated as the current temperature of the origin patch ($T_o^c$) minus the future temperature of the destination patch ($T_d^f$) (Fig. S1). This table describes the percent area of all patches with positive margins, meaning they are successful at achieving climate connectivity. Adj indicates results for climate connectivity due to adjacency only. Cor indicates results for climate connectivity due to adjacency and corridors. The A2 emission scenario (bold) (18) is the mean ensemble of 15 projected temperature models for 2050–2099 (19). All others are RCP scenarios (RCP2.6, RCP4.5, RCP6.0, and RCP8.5) and are based upon a Model for Interdisciplinary Research on Climate 5 (MIROC5) model for each scenario (40).
