Assessing Climate Change Vulnerability of Breeding Birds in Arctic ...

Figure 3.5. Changes in the CCVI tool score and vulnerability category output using input from different globalcirculation models (GCMs) for presumed stable through highly vulnerable bird species. (a) Temperature data: A1BSRES emission scenario, SNAP 5-model composite (ECHAM5, GFDL2.1, MIROC, HAD, CCCMA), 2 kmresolution; (b) Temperature data: A1B SRES emission scenario, SNAP CCCMA GCM output, 2 km resolution; (c)Temperature data: A1B SRES emission scenario, SNAP 5-model composite ECHAM5 GCM, 2 km resolution.While the index scores vary somewhat across models, only those highlighted in blue changed category from theinitial run in Figure 3.6a. [Note: Moisture projections from all models show little change to increases for theassessment region. Moisture had little influence over CCVI results in this assessment and is not shown here.]24
