Today, in our environmental science lecture, we will discuss the impact of urban green spaces on city temperatures. Recent studies have shown that parks and gardens can reduce local temperatures by up to 5 degrees Celsius during heatwaves. This cooling effect is mainly due to shade provided by trees and the process of evapotranspiration, where plants release water vapor. However, the effectiveness depends on the size and density of the green area. Small, scattered gardens have a limited impact, while large, connected parks can create a 'cool island' that benefits surrounding neighborhoods. So, city planners should prioritize creating larger, interconnected green spaces rather than many tiny ones.
