To learn where action is needed to protect vulnerable populations now and in the future, CPO’s National Integrated Heat Health Information System (NIHHIS) and partners are launching new community-led campaigns that will map the hottest parts of cities in 11 states across the country this summer. The communities include Albuquerque, New Mexico; Atlanta; New York City; Charleston, South Carolina; Kansas City, Missouri; Raleigh & Durham, North Carolina; San Diego; San Francisco; and parts of New Jersey, Indiana, Massachusetts, and Virginia.
