An archaeologist who specializes in South America and the Caribbean, and particularly in the historical effects of climate change on insular communities, Jago Cooper is currently the curator of the Americas Department of the British Museum. As well as his work at the museum, he has written and directed a number of programmes for BBC Four in which he disseminates his fieldwork and reveals some of the ancient mysteries of Latin America. He will talk to Gabrielle Walker, a Doctor of Chemistry from Cambridge University and the author of four books about climate change.
