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 dark, heat-absorbing surfaces such as asphalt and rooftops, coupled with the scarcity of vegetation. Recent studies indicate that the intensity of UHIs can be mitigated through the implementation of green infrastructure, including green roofs and urban parks, which enhance evapotranspiration and provide shade. However, the effectiveness of such measures varies with regional climate conditions and urban morphology, suggesting that a one-size-fits-all approach is inadequate. Consequently, policymakers are urged to adopt localized strategies that integrate climate data with urban planning to optimize thermal comfort and reduce energy demands.

B. B. Su eficacia depende del clima local y de la estructura urbana.
C. C. Aumenta el consumo de energía a largo plazo.
D. D. No tiene ningún impacto en los resultados de salud pública.
✅ 正确答案
B. Its effectiveness depends on local climate and urban structure.
