📖 Reading Passage

The phenomenon of urban heat islands (UHIs) has garnered significant attention in climate research due to its implications for energy consumption and public health. UHIs occur when metropolitan areas experience higher temperatures than their rural surroundings, primarily because of the prevalence of concrete and asphalt, which absorb and re-emit solar radiation more effectively than natural landscapes. Additionally, waste heat from vehicles and air conditioning units exacerbates the effect. Recent studies suggest that incorporating green infrastructure, such as rooftop gardens and permeable pavements, can mitigate UHI intensity by enhancing evapotranspiration and reducing surface albedo. However, the effectiveness of these measures varies with local climate, urban density, and seasonal weather patterns, necessitating tailored adaptation strategies for different cities.
