Climate Change, Displacement and International Justice

Climate change is widely expected to lead to widespread displacement and migration worldwide. Rising sea-levels, flooding, heatwaves and drought are threatening the livelihoods of hundreds of millions of people. Climate justice requires us to respect and protect the human rights of people facing climate-related displacement. What rights do climate migrants have, and whose responsibility is it to assist those who seek to escape the ecological threats that climate change produces? Does international law offer sufficient legal protection for displaced people? Or do we need to strengthen international protection regimes for climate migrants?
