As large swathes of the Caribbean have been left devastated by Hurricane Irma, the issue of climate change is once again back on the global news agenda. It’s easy to feel defeated when the environmental crises we face are so immediate and huge. But action is urgently needed. In this special edition of the Weekly Economics Podcast (recorded before Irma took place), we explore some of the possible solutions, debate what real action looks like and how those most affected can be the most powerful agents for change. David Powell, Environment Lead at the New Economics Foundation, takes over hosting duties and is joined by Alice Bell, Director of Communications at 10:10, and Asad Rehman, Executive Director at War on Want. — Enjoying the show?
