Ruth Townend is joined in the studio by Gwynne Dyer, author of Climate Wars, and Chatham House's own Dr Daniel Quiggin to talk about climate solutions from the magical to the mundane. For his forthcoming book Intervention Earth, Dyer has spoken with more than 50 thinkers, innovators and engineers about how we might cool the planet and avoid catastrophe.

Dyer, Quiggin and Townend explore the potential of unicorns, workhorses, and the odd dark horse technology, discuss the moral hazard of reliance on unproven technology, and consider the role of both technology and governance in meeting the Paris Agreement goals.

You can find out more about Gwynne Dyer's work on his website, and read Daniel Quiggin's work on the role of the aviation industry in reaching net zero on the Chatham House website.

Presented by Ruth Townend. Sound by Alex Moyler.
