Climate Central developed an Urban Heat Intensity Index for 159 U.S. cities, finding that New Orleans, Newark, New York City, Houston, and San Francisco have the highest intensity scores. The report identifies albedo, lack of greenery, population density, and building height as primary drivers of the UHI effect. These conditions exacerbate heat waves, worsen air quality through ground-level ozone formation, and disproportionately affect vulnerable populations, particularly those in formerly redlined neighborhoods. Proposed solutions include short-term emergency cooling measures and long-term infrastructure changes such as planting trees, installing green and cool roofs, and deploying solar energy.
