Today in our environmental science lecture, we'll discuss the impact of urban green spaces. Recent studies show that adding parks and community gardens can reduce local temperatures by up to 3 degrees Celsius, mainly through evapotranspiration and shade. However, the effectiveness depends on the size and connectivity of these areas. Small isolated patches have limited cooling effects, while larger interconnected networks can create 'cool corridors' that benefit surrounding neighborhoods. Interestingly, the study found that trees are more effective than grass in lowering daytime heat, but grass cools better at night. This has implications for city planning, especially in heat-vulnerable districts.
