The phenomenon of urban heat islands (UHIs) has garnered significant attention in climate research due to its profound 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 heat-absorbing materials such as concrete and asphalt, coupled with the scarcity of vegetation. Recent studies indicate that the intensity of UHIs is exacerbated by anthropogenic heat release from vehicles and air conditioning systems. Mitigation strategies, including the implementation of green roofs and reflective pavements, have been proposed, yet their effectiveness varies with local climate conditions and urban morphology. Consequently, urban planners are urged to adopt context-specific adaptation measures rather than relying on universal solutions.
