The last panel presented a ‘net assessment’ of the risks to international security presented by climate change. Lieutenant Colonel Ian Astley, of the Global Strategic Trends Programme within the UK Ministry of Defense’s Development, Concepts and Doctrine Centre, gave a presentation arguing that climate change is a ‘ring road issue’, in that it will affect all other areas of security.
Though it will not cause conflict, it will adjust the tipping points of other societal factors, making conflict more likely. Cleo Paskal, an Associate Fellow in the Energy, Environment and Development Programme at Chatham House, focused her presentation predominantly on how climate change will affect maritime security, particularly as it relates to China. Jeffrey Mazo, the IISS Research Fellow for Environmental Security and Science Policy, gave a presentation that focused on how vulnerability to climate change correlates with areas of the world with already weak or failing states.
