Every generation faces challenges that previous generations could scarcely imagine. Twenty years ago, few people were talking about climate change, now it's one of the most hotly-contested areas in politics.How do artists, writers, musicians and broadcasters respond when a new subject appears that is as large and significant as this? What kind of novels, plays, paintings, sculptures, movies and music begin to emerge?‘Mediating Change’ is a four-part series, chaired by BBC Radio 4’s Quentin Cooper, which looks at what happens when culture meets climate change. In each podcast, Quentin is joined by a panel of experts. The panellists range from artists and curators to academics andjournalists. There’s also a campaigner and a comedian. Together they explore the cultural response to climate change: where it started, what it looks like today, who it’s aimed at, and where it’s going.Mediating change is produced by The Open University in partnership with the Ashden Trust.Thanks to the Tipping Point Conference 2010, Eden Project, Open University at Camden and National Theatre Studio where the conversations were held.Artwork: 'Endangered Species' by choreographer, Siobhan Davies
