Heat Vulnerability Mapping: Designing Visual Tools that Effectively Communicate Risk

Kathryn Lambrecht

Abstract

As the impacts of extreme heat escalate, digital maps have been designed to triangulate the location, timing, and level of risk. To understand how these tools align with a range of heat communication needs, rhetorical topology is used to analyze three mapping tools that make projections at global, national, and local levels. While these tools seek to make heat risk visible, the reliance on numerical definitions and comparative statistics gets prioritized over lived experiences of heat, which could limit their impact. I argue that broadening the focus to include causal relationships and narratives may communicate extreme heat risk more equitably.
