With a major heatwave ahead this weekend, NOAA Climate.gov will host an extreme heat tweet chat this Friday, July 19, from noon to 1 pm Eastern. Four heat health experts will answer questions about how extreme heat is changing, the impacts extreme heat has on people, and how communities are working together to make themselves more climate resilient.

Community organizers in eight U.S. cities have been offered support for UHI mapping campaigns through the National Integrated Heat Health Information System (NIHHIS) and CPO’s Communication, Education, and Engagement Division.
