2 ways cities can beat the heat: Which is best, urban trees or cool roofs?

As cities heat up, the search for smarter cooling strategies grows more urgent. New research shows that two simple tools—planting trees and installing reflective “cool roofs”—can make a measurable difference. But not every solution fits every street. Trees work wonders where they can grow, but in dense or drought-prone areas, light-colored roofs might be the better bet. The key? Tailoring the response to the neighborhood. With the right mix, cities can cut heat, lower energy bills, and protect vulnerable residents—all without breaking the budget. Ian Smith with The Conversation has the full story.
