The “Frontiers in Earth Science” journal published an article: “Changes in the Thickness of Ice Cover on Water Bodies Subject to Human Pressure (Silesian Upland, Southern Poland)”, by Dr. M. Solarski and Prof. M. Rzętała. Thirty-nine water reservoirs located in the Silesian Upland, which are subject to various anthropopressure influences, were investigated. The aim of the research was to determine to what extent the air temperature and the thickness of the snow cover influenced the thickness of the ice cover during the three winter seasons. In addition, it was determined to what extent the morphometric features of the reservoirs (area, capacity, average depth) as well as the average water temperature and the thickness of snow accumulating on the ice affect the average and maximum thickness of the ice. The research shows that the vast majority of the studied reservoirs (35) are characterized by a quasi-natural ice regime, in which the variation in the thickness of the ice depends primarily on the course of the air temperature and the variation in the thickness of the snow that accumulates on the ice during winter. In the remaining 4 cases, the inflow of warmer underground water from the mines was the element that had a decisive influence on the thickness of the ice.
