Immigration, which previously occured as a result of economic motives, is today a mixture of forced processes, coressponding to forfeit one’s place. The changing nature of immigration on one hand indicates that it is becoming more global and also illegal, and on the other hand that it has become almost the last strategy of many people for survival. Climatee refugees, who are forced to temporarily or permenantly leave their traditional living space because of environmental insecurities caused by global warming, are signs of this reality. This study aims to show the changing structure of immigration process and the role of global warming in this change. It argues that the issue of climate refugees, which is related to environment as well as human rights and security issues, is not only a problem of immigration but also it is a phenomenon in which people loose their living space, and therefore which contains potential conflict risks.
