Green Space Cools Cities

According to a recent study, adding parks in urban spaces can cool the city by as much as 4°C.

Vegetation cools local temperatures when the water it has absorbed is evaporated from its leaves – much like the cooling effect of perspiration. The researchers say that the increased greenery would not have to involve building new parks. For instance, green roofing – roll-out strips of soil planted with succulents, commonly used in Germany – would have a similar effect.
