13.4 Regional RMSs that Address Climate Change Vulnerabilities The climate change working group, known as the Core Group, articulated and prioritized regional climate change vulnerabilities and adaptive management strategies, as described in Chapter 11 Climate Change. Table 13-4 identifies applicable regional RMSs that address high-priority climate change vulnerability issues. 13-4.
