Resumen: The denomination of individuals affected by ecological migrations has often changed since the problem was first identified in 1985. In consideration of the subjective component, they are referred to as refugees, displaced persons or emigrant s; in consideration of the reason that triggers their displacement, they are named environmental, ecological or climatic. The nine variants which result from the combination of these two sets of words conform the standard terminology in the matter. In part icular, the use of the term ‘refugees’ seems to claim a correspondence with that of ‘political refugees’, and the adjective ‘climatic’ seems to impose a financial responsibility on the developed economies.
