Duncan Depledge is a Research Analyst working on the Climate Change and Security Programme at the Royal United Services Institute, London. He holds an M.Phil in Geographical Research from the University of Cambridge, as well as an MA in Political Theory and a BA (Hons) in History from the University of Sheffield. His postgraduate research explored the remarkable changes that have occurred in UK security discourses since 1997 in response to the growing prevalence of climate change and other environmental issues. Duncan's latest research at RUSI focuses on the implications of climate change for UK national and international security, and he has contributed to recent RUSI studies on climate change implications for global governance, and climate-related security impacts in Mesoamerica and China. Duncan is also undertaking a Ph.D under the supervision of Professor Klaus Dodds at Royal Holloway, University of London. His thesis will focus on the implications of climate change for Arctic geopolitics.
