The phenomenon of urban heat islands (UHIs) has garnered increasing attention in climate research due to its significant 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, which replace natural vegetation. Additionally, anthropogenic heat emissions from vehicles, air conditioning, and industrial processes exacerbate this effect. Studies indicate that the intensity of UHIs correlates with city size, population density, and the absence of green spaces. Mitigation strategies, including the implementation of green roofs and reflective pavements, have been proposed, yet their effectiveness varies with local climatic conditions and urban morphology. Understanding these dynamics is crucial for urban planners aiming to design sustainable cities that can adapt to global warming.
