As the science of climate change becomes increasingly well understood, the ramifications of projected increases in temperature, changes to rainfall patterns, rises in sea-level and increase in extreme weather events require attention from policy-makers worldwide. This is particularly apparent in relation to migration, refugees and international security, with climate change acting as a threat multiplier to exacerbate existing tensions and instability. The Institute of Environmental Studies, in conjunction with the Climate Change Research Centre, the Faculty of Law and the Refugee Council of Australia held a public forum at UNSW on these very issues featuring Professor Andy Pitman, Dr Jane McAdam and Anna Samson.
