Your kitchen fridge is merely the surface of a global, planet-altering cold chain.
In short: Food storyteller Nicola Twilley examines the massive artificial Arctic we have constructed to maintain food freshness. She explains how this global refrigeration network is contributing to the melting of the real Arctic and discusses emerging technologies that could sustain our food supply without further damaging the climate.
The modern cold chain is a vast, interconnected system that extends far beyond the appliance in your kitchen. While this infrastructure is essential for keeping food fresh, it creates a paradox: the energy and processes required to maintain this artificial cold are actively accelerating the warming of the natural environment.
Recorded at the TED Countdown Summit on June 17, 2025, Twilley highlights that we have reached a critical juncture. The talk explores how we might rethink our reliance on these cooling systems and introduces potential technological innovations that promise to preserve food quality while reducing the environmental impact of our global refrigeration habits.
