It is always more evident that something in the climate is changing, everybody can see it on their own, but evaluating the numbers supporting the change it is not always so simple. In an area where the water quantity is actually not a problem, the global warming identified through the meteorological data analysis of the historical time series seems to have consequences on the phreatic aquifer of the Isonzo /Soča River Plain (NE Italy). The analysis of the piezometric levels in facts show a decreasing trend actually still sustainable but not sustainable any more if compared to the climate models at 100y showing a temperature increase and a decreasing in the precipitation amount.
