Today in our environmental science lecture, we discussed the impact of urban green spaces on city temperatures. Professor Thompson explained that parks can reduce local temperatures by up to 5 degrees Celsius due to shade and evapotranspiration. However, he emphasized that the size and distribution of these spaces matter more than their total area. For instance, many small pocket parks scattered across a city are more effective than one large central park, because they cool a wider range of residential areas. He also noted that adding green roofs to buildings can further enhance this effect, but the initial cost remains a barrier for many municipalities.
