Throughout October and November we're bringing you the special podcast mini-series ‘Climate Change and National Security’, in the run up to the 2021 United Nations Climate Change Conference (COP26), hosted by the Environmental and Security Research Group in the School of the Security Studies. How do different states view the relationship between climate and security? Is there a best practice for climate security and a sense of momentum as we move into COP26? Should we be worried about the securitisation of the climate agenda? In the first of this five part mini-series Climate Change and National Security, Professor Matt McDonald from the University of Queensland and Dr Duraid Jalili from the King's Environmental Security Research Group consider different governmental responses to climate change and national security from '50,000 feet’.
