Today in our environmental science lecture, we'll discuss urban heat islands. Professor Thompson explained that cities are often warmer than surrounding rural areas due to concrete and asphalt absorbing heat. He highlighted a study in Melbourne, where adding green roofs to buildings reduced local temperatures by up to 2 degrees Celsius. However, he noted that the most effective solution is increasing tree canopy along streets, as trees provide shade and release moisture. Interestingly, he mentioned that white-painted roofs reflect sunlight, but their effect is smaller in humid climates. Finally, he emphasized that planners should prioritize green spaces, not just for cooling, but also for improving air quality and residents' mental health.
