Critical thresholds, extreme weather, and building resilience in the south central United States
This case study explains the findings from a project on building resilience in the South Central United States, in four small to medium-sized communities (Boulder, CO; Las Cruces, NM; Miami, OK, and San Angelo, TX). A multidisciplinary team used a participatory process to engage local citizens and identify locally relevant critical thresholds for extreme events, and use these thresholds to customize climate projections to community-specific needs. Identifying and better understanding critical thresholds for extreme events is key to developing effective community responses to climate change.
The team learned several lessons from applying this participatory approach to building community climate resilience:
- Successful co-production of actionable science, based on the extreme weather events thresholds concept, show potential to bridge the gap between climate science and on-the-ground action to build resilience.
- Both broad stakeholder engagement and expected attrition in participation can be used to strengthen efforts to build community climate resilience.
- Communities are interested in threshold levels more extreme than those typically selected in scientific analyses, and in a wider range of extremes.
- Communities are opportunistic when acting to build community resilience. In most cases, the communities chose resilience projects that fit with on-going efforts.
- Each community selected a project that has co-benefits and helps build more than one aspect of resilience.
- The threshold concept is useful as an entry point for discussions about climate change.
