One of the direct consequences of climate change lies in its impacts on the hydrological cycle: the recurrence of extreme positive and negative anomalies of precipitation is set to become more and more frequent, while the rising of global temperatures is already impacting on freshwater availability,or excess, in many regions of the world. The Great Alpine Region (GAR), i.e. the geographical area comprising the European Alps and their close proximity, is in this context a particularly impacted spot as it is showing high levels of both exposure and vulnerability to climate change. This is especially relevant because of the importance of the Alps for the freshwater resources across the whole continent.
