Climate change spares hardly any body of water, and not only in southern Europe. Because of the heat waves last summer, many groundwater levels are at a record low.

The consequences are also being felt in Burgenland in Austria: Lake Neusiedl continues to dry up. Now the mayor of the neighboring municipality of Jois is also concerned. 200 residents and 40 tractors blocked the B50, the most important federal highway – for four hours on Tuesday (9 May) The drying up of the lake is an "imminent environmental catastrophe", says the mayor.
