The Rhine and Danube have indeed become shallower, but it's not just drought that's causing it. Summer heat in 2022-2024 led to evaporation and lowered groundwater levels that feed these rivers. Plus global warming is changing how snow melts in the Alps - it used to happen gradually throughout the season, now it's all compressed into a shorter timeframe. In practice, this means tankers operate at half capacity, power plants run their hydroelectric facilities at minimum, and some regions have faced water supply restrictions. Europeans are still working out long-term solutions: dredging work, backup channels, switching to alternative transport and energy sources - but that's not something you solve in one season.
