Today in our environmental science lecture, we'll discuss urban heat islands. As cities grow, concrete and asphalt absorb sunlight and re-emit heat, making urban areas warmer than surrounding rural regions. One effective mitigation strategy is increasing green spaces, like parks and green roofs. Trees provide shade and release moisture through transpiration, which cools the air. However, studies show that the cooling effect is most significant when green spaces are connected, forming corridors, rather than isolated patches. This connectivity allows cooler air to flow into built-up areas. So, when planning new developments, city planners should prioritize linked green networks over single large parks.
