📖 Reading Passage

The phenomenon of urban heat islands (UHIs) has garnered increasing 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 dark, heat-absorbing surfaces such as asphalt and concrete, which replace natural vegetation. Additionally, anthropogenic heat from vehicles, air conditioning, and industrial processes exacerbates the effect. Recent studies indicate that the intensity of UHIs can be mitigated through strategic urban planning, including the incorporation of green roofs, reflective materials, and increased tree canopy. However, the effectiveness of these measures varies with local climate, city layout, and socioeconomic factors, necessitating tailored approaches rather than one-size-fits-all solutions.
