Heat waves are becoming more common and intense in Washington state and beyond as a result of climate change, increasing the risk of heat-related illnesses and death. Climate Impacts Group researchers Zach Kearl and Jason Vogel studied the impacts of extreme heat on public health in urban and suburban areas of Washington state. Their resulting paper, Urban extreme heat, climate change, and saving lives: Lessons from Washington state, was recently published in Urban Climate. The paper examines the key factors conditioning public health impacts of extreme heat and a suite of policy options in Washington state.

Kearl and Vogel found extreme heat affects subpopulations differently because of various contextual factors and social determinants of health; this suggests a wide range of policy alternatives is necessary to meaningfully improve health outcomes community wide. Moreover, the array of policy alternatives identified often rely on programs and agencies whose missions do not explicitly prioritize public health. They conclude that without mechanisms for formal coordination among implementing partners and agencies with a role in protecting public health, important policy alternatives that serve vulnerable subpopulations will likely be neglected.
