| Summary: | Climate change is the most important environmental problem facing humanity in this century. And it has become the great axis of public policies and private actions in developed societies. The effects of altering the planetary energy balance due to anthropogenic greenhouse gas emissions are already becoming evident in some regions of the planet. Among them, the evidence is already significant in the areas with a Mediterranean climate. This paper collects, as a review paper, the evidence and trends that are being recorded in two areas with a Mediterranean climate (the Spanish Mediterranean coast and the central sector of Chile) to assess the effect of the global warming process. The impact that the current climate change is having on the main elements of the climate and on specific environmental processes in both of these geographical spaces has been analysed. The study seeks to update, through an evaluative summary, the state of the issue of climate change in Mediterranean areas, indicating its future impact on elements of the natural environment and on the functioning of the societies that exist in these regions.
