Air conditioning is not enough to keep people cool — can scientists find an alternative?

TL;DR - Nature highlights advances in materials that could passively cool buildings as temperatures rise. The provided excerpt is brief, so it does not identify specific materials or quantify their performance.

• Air conditioning alone may be insufficient for keeping people cool in a warming climate.
• Emerging materials could reduce building temperatures through alternative cooling approaches.
• Such materials may complement conventional air conditioning and reduce reliance on energy-intensive cooling.
• Technical methods, experimental results, and deployment constraints are not included in the provided content.
