According to Axios, Massachusetts in August became the first East Coast state and the second in the U.S. after Arizona to appoint a heat resilience officer, as states move to build systems for extreme heat that they were not historically designed to handle. The state has warmed by nearly 3.5°F over the past century, and Massachusetts Department of Public Health data showed nearly 1,500 heat-related emergency room visits last year. Heat resilience officer Katie Schlick said 1 in 5 Massachusetts public schools lacks air conditioning.
Arizona's 2024 heat plan created a chief heat officer role to coordinate heat-response efforts across agencies, expanded heat-relief resources and deployed mobile solar-powered cooling centers made from shipping containers. Visits to two cooling centers at the Arizona Capitol rose 59% in summer 2025 from a year earlier, according to the state. California does not have an official with that title, but it has an office dedicated to extreme heat and a funding program for communities, while its 2022 Extreme Heat Action Plan established what officials called the state's first all-of-government framework for extreme heat. California's updated 2026 plan covers public health, emergency response, housing, infrastructure, energy and worker protections, and a separate law will require cities and counties to address extreme heat hazards when they next update certain general plan elements on or after Jan. 1, 2028.
