Frostbite: Nicola Twilley and the global chill required to keep food moving around a warming planet

In this episode, host Amy O’Neill Houck speaks with Nicola Twilley, a journalist and frequent contributor to The New Yorker, and host of the podcast Gastropod. Nicola tells us about her new book, Frostbite: How Refrigeration Changed Our Food, Our Planet, and Ourselves and lets us in on the global effects that keeping food cold has had on the food system, on humans as eaters, and on our warming planet.

Over the last 150 years, refrigeration has reshaped how we produce, distribute, and consume food, sparking the industrialization of agriculture and influencing everything from meat production and nutrition to food waste. Yet, this cold revolution hasn’t come without costs—refrigeration is a major contributor to greenhouse gas emissions due to its energy demands and refrigerant gasses. Twilley explores how we might reimagine refrigeration for a food system that prioritizes public health, environmental sustainability, and equitable food access.
