Experts Call for Extreme Heat Action Plans as Communities Face Growing Risks

As extreme heat continues to be the leading cause of climate-related deaths in the U.S., experts emphasize the need for improved tracking, response strategies, and community awareness. While the Centers for Disease Control (CDC) reported 2,300 heat-related deaths last year, studies suggest the actual toll may be much higher, with California among the hardest-hit states. Efforts are underway to create more effective heat warning systems, including a new pilot program in California aimed at improving the availability of real-time data on how heat affects individuals, potentially guiding more immediate protective measures in homes, schools, and workplaces.

Communities are exploring various strategies to combat extreme heat, such as planting more trees, increasing access to air conditioning, and establishing cooling centers. However, experts argue that more targeted information is needed to ensure people can make informed decisions about their exposure to heat. Researchers are now studying how individual physiological differences affect responses to heat, which could lead to personalized heat warnings. For example, mobile apps could provide tailored recommendations based on current weather conditions and personal health data to help individuals avoid dangerous heat exposure.

California has already begun implementing its Extreme Heat and Community Resilience Program, which allows local governments and organizations to apply for grants to develop cooling strategies such as increasing shade and making buildings more heat-reflective. In addition, UCLA's new Center for Heat Resilient Communities is spearheading efforts to develop a comprehensive blueprint for building heat-resilient communities. Over the next three years, the program will collaborate with 30 communities nationwide to field-test practical solutions, aiming to help local areas adapt to increasing heat risks and improve public health outcomes.
