David Keys has been The Independent’s Archaeology Correspondent since the paper started in 1986. He has worked in journalism (staff and freelance; newspapers, magazines, radio and TV) for 45 years - and has specialized successively in home affairs (1970s), foreign affairs, aviation and international trade (1970/80s) and archaeology/history (after 1986). He has visited more than a thousand archaeological and historical sites in 60 countries – and, over recent years has originated and/or acted as consultant on 40 archaeology/history TV documentaries.

His major book - Catastrophe, an Investigation into the Origins of the Modern World - explores the relationship between climatic problems and history. A new edition is about to be published on kindle – and will include major new revelations about how modern climate change is likely to impact the world economically and politically. www.david-keys.com, dmekeys@gmail.com
