What makes a person a climate refugee? The human cost of global environmental changes
Climate change is forcing millions of people to leave their homes yet climate refugees and climate-induced migration are not legally recognised.
There are about 20 million refugees globally, according to the United Nations High Commissioner for Refugees (UNHCR).
Refugees and migration are rarely far from the headlines – the Syrian refugee crisis continues and thousands of people from countries such as Afghanistan and Eritrea are dying as they try to cross the Mediterranean Sea.
But not all refugees are fleeing conflict. As global temperatures increase at rates exceeding most scientific predictions, more and more of the global population are feeling the impacts of climate change.
