Danube drought exposes WWII ships, disrupts shipping

Europe’s drought has pulled water levels on major rivers down so far that sunken World War II warships are resurfacing and ancient fossils are reappearing along riverbeds.

The Danube, the continent’s second-longest river, is at historic lows after months of extreme heat and little rain. In Romania, the receding water has uncovered the bones of a woolly mammoth that lived tens of thousands of years ago. In Germany, fishing boats are stranded on the dried-up banks of the Rhine, while sections of France’s Loire have turned into cracked mudflats.

Water levels on the Danube near the Romanian port of Orșova have dropped below 50 centimeters in places, exposing the rusting hulls of at least 24 German warships scuttled by the country’s navy in 1944 to avoid capture by Soviet forces. Local officials say the wrecks, normally hidden by 3–4 meters of water, are now visible for the first time in decades. In the same region, archaeologists digging into the riverbed found a near-complete mammoth skeleton, including tusks and molars, preserved in sediment for roughly 20,000 years.

The drought is part of a wider climate trend: Europe has seen its driest summer in 500 years, according to the EU’s Copernicus climate service. Rivers carry roughly a third of the continent’s freight, and low water has already cut shipping capacity on the Rhine by about 40% this year, forcing cargo companies to slash loads and raise prices. Scientists warn that shrinking rivers could become more common as temperatures rise, making it harder to move goods, cool power plants, and protect fragile ecosystems. With no major rainfall forecast in the coming weeks, officials are bracing for further disruptions and the chance of more long-buried history—or hazards—being revealed.
