The lightest-colored area at the heart of the map below shows the area with the least amount of heat, as measured by the King County Heat Mapping Project. The opening two paragraph of the press release about this new mapping project, issued by King County Executive Dow Constantine:
“King County and City of Seattle today announced the results of a groundbreaking heat mapping project that quantifies the harmful, inequitable impact that hotter summers are having on the region. The data show that surface-level temperatures in areas with paved landscapes, less tree canopy, and industrial activity are substantially higher during summer heat events compared to less urbanized areas.
“King County Executive Dow Constantine outlined how the study results will inform work across departments and initiatives to mitigate the impact of hotter summer temperatures, which is exacerbating inequities.”
