Today in our environmental science lecture, we'll discuss the impact of urban green spaces. A recent study in Melbourne found that parks can reduce local temperatures by up to 4 degrees Celsius during heatwaves. However, this effect depends on the size and tree density of the park. Small gardens with scattered trees have minimal cooling impact, while large, densely planted areas create a significant 'cool island' effect. Interestingly, the study also noted that water features, like ponds, contribute to humidity but do not lower temperature as effectively as tree shade. So, for cities aiming to combat rising heat, investing in large wooded parks is more beneficial than adding small green pockets.
