This summer, hundreds of millions of people have endured temperatures above 35°C. Around the world, schools are closing, wildfires are burning, hospitals are overwhelmed, and workers are losing productive hours in conditions that were once rare and are now routine. The trajectory is clear: heat is no longer a future risk, it's a present crisis reshaping daily life on every continent. Access to effective, sustainable cooling has become one of the defining resilience challenges of the climate era, yet today's solutions are often energy-intensive, inequitably distributed, and inadequate for the scale of what is coming. Part of the Top 10 Emerging Technologies series, this session will explore the next generation of climate technologies designed to help societies adapt to a hotter world while reducing the environmental footprint of cooling itself. Experts will discuss innovations in energy-efficient cooling, heat-resilient infrastructure, advanced materials, passive design, thermal storage and climate-smart urban systems. The conversation will examine the technologies that could help communities adapt to rising temperatures, the obstacles to scaling them, and the policies and investments needed to deploy them at speed — and at scale — across the world.
