Today in our environmental science lecture, we'll discuss the impact of urban green spaces on local climate. A study conducted in Melbourne compared two neighborhoods: one with extensive tree cover and another with minimal vegetation. The results showed that the tree-covered area had surface temperatures up to 4 degrees Celsius lower during summer afternoons. Additionally, residents in the greener neighborhood reported using air conditioning 15% less frequently, which led to a noticeable reduction in energy consumption. However, the researchers noted that the cooling effect was strongest within 50 meters of large trees, and it diminished significantly in open paved areas. So, for urban planners, strategic placement is key.
