But the cooling achieved by such programs is debated, as previous analyzes focus on much smaller scales than the city-wide ones planners are working on. To fill this gap, we performed a scaling analysis of cooling efficiency (CE)\u2014the temperature reduction associated with the 1% growing tree canopy (UTC)\u2014to predict citywide CE. The results show that CE increased with increasing spatial scales in a convex power form. The power law was consistently found across multiple cities with different climate contexts and was also robust under different summer weather conditions within the city. Power-law scaling of CE can provide a tool for urban planners to set UTC targets for extreme heat mitigation.
