This is important for managing heat on a human level in cities. So I'm not saying this is stupid.
But don't get this twisted: This is useless for addressing the climate change problem. It's not even a bandaid on a stab wound, this is equivalent to offering someone bleeding out a glass of warm water and fanning them with a brochure about new plastic doodads. A trillion trees planted tomorrow wouldn't even be a pebble on the pavement to that SUV flying down the fiery freeway.
