Climate Change and Public Policy
  • Regard people as a “keystone species,” not just extracting ecosystem services
  • Require combination of social and ecological systems
    • Respond to new information and understanding
  • Combination of adaptation and mitigation
    • Integrated and inclusive approaches to policy formulation and refinement
