Answer:
installing cool roofs and increasing tree canopy can lower heat island temperatures and lessen the exposure and sensitivity of city residents to climate change impacts, while also lowering the greenhouse gas emissions that cause climate change.
Installing high-albedo roof surfaces, using roofing materials with high SRI value, and installing a vegetated roof that covers at least 50% of the roof area are all ways to reduce heat island effect on a roof.
Heat islands form as a result of several factors: Reduced Natural Landscapes in Urban Areas. Trees, vegetation, and water bodies tend to cool the air by providing shade, transpiring water from plant leaves, and evaporating surface water, respectively
Heat waves occur naturally in the summer, but climate change is exacerbating these events because emissions of heat-trapping greenhouse gases are causing average temperatures to increase.
Why do we care about urban heat islands? Elevated temperatures with urban heat islands affect a community's quality of life and can adversely impact both natural and built environments.

Explanation:
Heat causes an increase in blood flow to the skin and pooling of blood in the legs, which can lead to a sudden drop in blood pressure. There can be a feeling of light-headedness before fainting occurs. Heat exhaustion – this is a serious condition that can develop into heatstroke.
During heat waves, the air becomes stagnant and traps emitted pollutants, often resulting in increases in surface ozone. Heat waves and drought also dry out vegetation and provide more fuel for wildfires whose smoke is a serious medical hazard. One type of cold wave also allows air pollution to accumulate.
