How to keep cool while the world gets hotter

Record-breaking heat waves and a growing reliance on fossil-fuel-powered cooling systems are accelerating a dangerous feedback loop, with global air conditioning usage projected to drive emissions up by 90% by 2050 if left unaddressed. To mitigate this crisis, innovators and policymakers are deploying a mix of passive building designs, natural cooling strategies, and urban greening initiatives in cities like Athens and Cairo to reduce temperatures without exacerbating the problem. Successful long-term outcomes depend on scaling affordable, low-energy technologies globally to ensure developing nations can meet cooling demands while avoiding high-end exclusivity and further environmental degradation.
