I would add that city people underestimate or simply do not know about the ability of vegetation to cool off its environment. My city has areas (few abandoned plots) with a wild high grass and bushes on them. When it’s hot and you walk nearby, like 2-3m close, it is as if you went from the street to under AC. I don’t know how they do it, but my guess is that photosynthesis is a hell of an endothermic process. And you’re right, modern “city trimming” is just a disgusting non-functional nonsense.

- compressedgas 5y agoIt's called transpiration. It is how the plants keep their temperature below the point at which photosynthesis no longer is possible.
- wruza 5y agoTIL. But that means plants move heat somewhere, and not pack it into chemical bonds. This maybe defeats the idea, because these areas are cold because they are rare. If ubiquitous, in a still hot day they would just raise humidity and probably make things worse?
- peterbraden 5y agoNot at all. The areas where they are ubiquitous, which we normally call forests, are still cool.
