Climate change - what lies beneath its widespread denial? Laurie Taylor talks to Sally Weintrobe, the editor of the first book of its kind which explores, from a multi disciplinary perspective, what the ecological crisis actually means to people. In spite of a scientific consensus, many continue to resist or ignore the message of climate communicators - but why? What are the social and emotional explanations for this reaction? They're joined by the Professor of Social Policy, Paul Hoggett. Also, Simon Abernethy looks at the history of class and commuting on the London Underground. Although builders and managers travel in the same coaches in the 21st century 'tube', the mixing of classes was once seen as revolutionary.
