The Climate Change Vulnerability Index (CCVI) uses a scoring system that integrates a species’ exposure to projected climate change within an assessment area, including sea level rise, and three sets of factors associated with climate change sensitivity, each supported by published studies: 1) species-specific sensitivity and adaptive capacity factors, 2) threat multipliers such as barriers to dispersal and anthropogenic threats, and 3) documented and modeled responses to climate change. Assessing species with the CCVI facilitates grouping unrelated taxa by their relative risk to climate change as well as identifying patterns of climate stressors that affect multiple taxa.
