The meteorologist, John Hammond explores how science fiction has long served as a barometer for our wonder, curiosity and sometimes anxiety about the environment. With expert insight from Sarah Dillon - Professor of Literature and the Public Humanities and Professor of Human Geography Mike Hulme, we find out how writers imagined – sometimes very accurately – the changing world around them.

We also hear from John's ÃÛÑ¿´«Ã½ Weather Centre colleague and friend, Sarah Keith-Lucas about the challenges of communicating complex science in an accessible and relevant way.

As we reach the turn of the millennium on our journey through fiction, we hear Patricia Cumper’s powerful drama 'Biomass' from 1999.
