This chapter examines the legal, human rights and ethical dimensions of the fact that human-induced climate change is already displacing people from their communities while threatening to create millions of climate refugees, that is people who are forced to leave their homes, communities and often their nations because of the adverse effects of global warming. Although as a matter of international law, the word refugee is often limited to individuals who are displaced from their country, this chapter will use the term refugee to include all people who are forced to leave their communities because of climate change without regard to whether they leave their nation and cross national boundaries.
