Today in our environmental science lecture, we'll discuss the impact of urban green spaces. A recent study in Melbourne found that adding parks and trees can reduce local temperatures by up to 4 degrees Celsius during heatwaves. However, the researchers noted that the effect depends on the density of vegetation and the size of the area. Small gardens with scattered trees have limited cooling, while large connected parks with dense canopy provide significant relief. Interestingly, the study also showed that green roofs on buildings are more effective in winter insulation than in summer cooling. So, for cities aiming to combat rising temperatures, prioritizing large green corridors is key.
