Today in our environmental science lecture, we will discuss the impact of urban green spaces on local climate. Recent studies show that parks can reduce surrounding temperatures by up to 5 degrees Celsius during heatwaves. This cooling effect is due to shade from trees and water evaporation from plants. However, the effectiveness depends on the size and density of the green area. Small gardens may only cool their immediate vicinity, while large connected parks can create wind corridors that benefit entire neighborhoods. City planners are now integrating these findings into design guidelines, prioritizing green roofs and vertical gardens in high-rise districts.
