The intensifying melting of glaciers in the Alps poses a challenge for the "water tower of Europe."

Recently, many areas in Europe have been experiencing high temperatures and little rain, causing the water levels of several rivers such as the Rhine and Danube to drop to historic lows. This has not only affected cargo transportation but also impacted river cruise tourism. Tang Bowen, Managing Director of Viking Cruises in China, told reporters that the routes on the Rhine and Danube are significantly affected at the moment. In some sections, the water levels are too low, which disrupts the normal navigation of vessels, necessitating flexible adjustments to itineraries.
