Cities around the world are getting dangerously hotter — not just from climate change, but from the concrete and glass we build. In this episode, we unpack the urban heat island effect: why cities can be 7–20°C hotter than surrounding areas, the massive economic costs in energy, productivity, and healthcare, and the surprising financial wins from smart solutions.

From reflective roofs in New York and cool pavements in Phoenix to restored rivers in Seoul and green corridors in Medellín, we explore real-world strategies that save money, protect health, and boost property values. Whether you’re an investor, policymaker, or city resident, this episode reveals why cooling our cities is one of the smartest economic decisions of our time.
