In 1951 diplomats from around the world met in Geneva, Switzerland to sign the UN convention relating to the status of refugees. The Convention was designed to address the most pressing cause of displacement in Europe at the time: the persecution of minorities and political opponents by authoritarian governments. In the years since, we've come to learn of a new threat: climate change. The changing climate and associated weather events are forcing many to leave their homes. The 1951 Convention does nothing to protect these people. So, what should be done?

One suggestion is that we sign a new convention, create a legal category for those displaced by climate change and award them a set of uniform rights. Jamie Draper from Oxford university is not convinced. Today. I asked him why. Also, what have philosophers had to say about climate displacement? What does justice demand in the case of sinking island states? And why are so many people against using the term “climate refugee”?
