Cold Comfort

Big Picture Science

Air conditioning and refrigeration may beat the heat, but they also present a dilemma. The more we use them, the more greenhouse gases we emit, the hotter the planet becomes, and the more we require artificial cooling. Can we escape this feedback loop? We look at the origins of these chilling technologies, tour the extensive chain of cold that keeps food from perishing, and consider how a desert city like Phoenix could not exist without AC.

Guests:

Nicola Twilley – co-host of the Gastropod podcast, a contributing writer at The New Yorker, and the author of “Frostbite: How Refrigeration Changed Our Food, Our Planet, and Ourselves”

Erik Morrison – Chief cooling engineer at Transaera, Somerville, Massachusetts

Stan Cox – Lead scientist at the Land Institute, author of “Losing Our Cool: The Uncomfortable Truths about our Air-Conditioned World”

Featuring music by Dewey Dellay and Jun Miyake
