At the edge of (un)inhabitability? Spatial diversity of demographic vulnerability to increasing heat exposure across remote towns of Northern Australia

The study provides a spatially detailed picture of the diversity in demographic vulnerability to increasing heat which is projected from climate change models for remote towns in Northern Australia, in both the immediate and long-term. Using a three-dimensional descriptive typology of warming, ageing, and population decline, the authors demonstrate that vulnerability does not increase uniformly with increasing remoteness but instead reflects the socio-economic and population diversity of these regions. 

The analysis highlights key distinctions among vulnerability types. While population ageing is widely recognized as a major challenge, Indigenous communities face heightened contextual vulnerability due to socio-economic disadvantage, which limits their coping and adaptive capacity. The findings underscore the need for place-based strategies to address the intersecting demographic and climatic vulnerabilities shaping the remote towns of Northern Australia in the face of projected increases in numbers of extremely hot days.
