Projected changes in 20-year maximum daily precipitation in summer (left) and winter (right) from 1961–1990 to 2071–2100 based on the ensemble mean using a regional climate model (RCM) nested in 6 general circulation model (GCMs). Changes that approximately lie outside of ± 10 % for the ensemble average are significant at the 10 % significance level.

Fresh water is scarce!
Some 97.5% of water on the Earth is salt water, leaving only 2.5% as fresh water. Of this over two thirds is frozen in glaciers and polar ice caps. The remaining unfrozen fresh water is found mainly as groundwater, with only a small fraction present in rivers, lakes or in the air. Water is a precious resource, use it responsibly and don’t waste it!
