The city and its partner organizations released the findings of a heat disparity study last month, and the results helped visualize how different communities across Chicago experience heat because of their geographic surroundings and infrastructure. 

Chicago was one of 18 communities selected by the National Oceanic and Atmospheric Administration (NOAA) back in April to participate in the agency’s annual urban heat island mapping program, a project to record and track heat disparities across geographic areas in municipalities. NOAA has run the project, which is funded through the NOAA Climate Program Office, since 2017.
