The Danube has fallen to one of its lowest levels in decades, exposing possible mammoth remains and a coal ship that sank in 1937

Imagine stumbling across the jawbone of a millions-of-years-old mammoth while strolling along a Bulgarian river on a hot July afternoon. This is not a feverish dream; this is just another day in the Danube basin, Europe's second-longest river, which has reached one of its lowest points in decades. As the waters recede, they are exposing some very bizarre lost and found items, including the remains of a mammoth, an old Nazi warship dating back to World War II, and an old Hungarian coal freighter that sank about 89 years ago in 1937.

According to the World Weather Attribution, a collaboration of climate scientists who analyze extreme weather events, the harsh heat and lack of precipitation during the summers have resulted in one of the worst droughts in years in Europe. The paper says that western Europe’s April–June drought now happens about once every five years, but would have been much less likely in a climate 1.4°C cooler. In the eastern region, the January–June soil-moisture deficit is now expected roughly every 15 years and is estimated to be about 11 times more probable because of human-induced climate change.

The mammoth in the room, literally


A villager came across some bones at the newly exposed riverbed in the village of Ryahovo in Bulgaria, prompting him to alert the local museum authorities. As per reports from CNN, the director of the Regional History Museum of the nearby city of Ruse said the find so far amounts to a lower jaw and two tusks, with a possible rib bone from the same animal, and that the bones are undergoing tests to confirm their age and species.

While this finding was a happenstance, there had been speculation regarding the presence of bones in this area for years. If the find turns out to be that of the woolly mammoth, it would add another entry to its impressive fossil history. A 2024 genomic study titled “Temporal dynamics of woolly mammoth genome erosion before extinction,” published in the journal Cell, found that woolly mammoths persisted on Siberia's Wrangel Island long after the species died out everywhere else, only going fully extinct around 4,000 years ago.

Meet the Fulton, the ghost ship nobody asked for

In Croatia, the drought managed to pull off an even more macabre glimpse into the past: the remains of the Hungarian cargo ship, the Fulton, that sank in 1937 while carrying coal down the Danube River. The same CNN report notes that the shipwreck has resurfaced in the town of Opatovac after lying hidden for nearly nine decades. However, in Serbia, the dropping river levels have also revealed another warship from World War II.

The part that’s actually more concerning

This is where the term "fascinating discovery" becomes a real nuisance. Apart from becoming a bonus for archaeologists, this particular catastrophic event has caused some real damage to the residents and the area. CNN's coverage describes that cruise boats are changing their routes or are being grounded, and one cruise boat with more than 180 passengers on board ended up stuck on a sandbar in Bulgaria. In addition, cargo boats have to reduce their cargo volume and thus slow down their operations and make them more expensive, resulting in increased prices of the transported goods, including those coming from Europe into America.

But what makes the current drought so unique is that it's not just a Danube problem; it is being intensified by human-made climate change, which World Weather Attribution's analysis links to sharply higher evaporation from soil, rivers, and reservoirs across the continent. That's the part that should resonate on this side of the Atlantic: the same atmospheric mechanics drying out the Danube are driving the heat waves scorching the American Southwest and the falling water levels at Lake Mead. While mammoth bones and sunken ships make for great photos, what they really represent is a warning sign, and not just a European one.
