Overview
- Record-low flows on the Danube and Rhine have pushed cooling water below safe thresholds, prompting Hungary to power down the Paks nuclear plant and Romania to take units at Cernavodă offline with outages that may last days to weeks.
- Cargo traffic is sharply impaired as vessels must sail with much lighter loads, Kaub on the Rhine is forecast to hit historic lows and freight costs and delays have pushed Rotterdam–Rhine volumes about 10% below normal.
- Hundreds of World War II wrecks near Prahovo have re-emerged and specialists in Bulgaria are examining mammoth bones found at Ryahovo, but many wrecks may hold unexploded ammunition so EU-backed salvage and clearance work is slow and safety-focused.
- The energy system is under strain beyond nuclear limits: hydropower reservoirs and river-cooled plants across central and western Europe have cut output, some industry has paused production and countries are increasing power imports or asking for voluntary cuts.
- Scientists link the heatwaves and drought to human-driven climate change and a strengthening El Niño, and officials warn that long-term river declines — Germany cites 60 billion cubic metres lost in 25 years — will raise future economic and energy risks without adaptation.
