Figure 3. Climate connections among refuges by 2070-2099. If an initial refuge node’s current climate space is found in other refuge nodes’ future climate (2070-2099), those nodes are final nodes and the arrowheads headed toward the final nodes. We used projections of future climate using two GCMs that respectively are hotter and drier (MIROC ESM), and warmer and wetter (CNRM-CM5) than current conditions. For each GCM we used two emission scenarios (RCP 4.5 and RCP 8.5) that represent lower and higher levels of greenhouse gas concentration. The size of the green circles represents the number of arriving climate connections to a unit or area.
