Today in our environmental science lecture, we're discussing urban green spaces. A recent study in Melbourne found that adding more parks and trees can reduce city temperatures by up to 2 degrees Celsius. However, the researchers noted that the effect is strongest when green areas are interconnected, like a network, rather than isolated. They also highlighted that rooftop gardens are less effective than ground-level parks for cooling, because they're often too high to influence street-level air. Interestingly, the study showed that even small pocket parks, if spaced regularly, can lower energy consumption in nearby buildings by about 10%.
