With climate change increasingly being seen as a security issue, we ask what role the United Nations Security Council could and should play. To answer this question, we are joined on the Climate Diplomacy podcast by UN expert and Chatham House Associate Fellow Oli Brown. In this podcast, Oli explains some of the challenges that the UN Security Council has had in tackling climate change and outlines the prospects for action in the future. Martin Wall is an Irish Research Council/European Commission funded Marie Curie CAROLINE Fellow who is currently seconded to adelphi and contributes to the Climate Diplomacy Project. He is funded through the European Union’s Horizon 2020 research and innovation programme under the Skłodowska-Curie grant agreement No 713279.
