NIEHS’s Climate Change and Environmental Exposures Challenge focused on creating data visualization tools and maps that connect current science on climate change to the exposure pathways for environmental hazards. The goal was to help decision makers and communities identify areas and people at greatest risk and help to prioritize protective actions. In this Part 2 of the 2-part series, we’ll hear about the other two winning projects: innovative visualization tool that identifies vulnerabilities related to flooding, air pollution, and extreme heat; and a website that shows area residents and decision-makers the potential hazards around the city and how that risk may change as climate change brings more flooding.
