Digitally scanning old waterways reveals new ways to cool cities impacted by climate change.
Flowing beneath the surface of cities around the world is an overlooked and sometimes forgotten resource. From Naples, Italy, to Seoul, South Korea, ancient aqueducts and buried streams make up a vascular system under the concrete, asphalt, and steel. As climate change turns up the heat, researchers argue that tapping this vascular system could be a way to cool cities from below.
