A passenger ship flying the Swiss flag was on the Danube. The captain attempted to drain water from a ballast tank to balance the ship. A mixture of water and diesel fuel was accidentally pumped into the river.
The captain of a passenger ship accidentally pumped several liters of diesel into the Danube. The captain actually wanted to drain water from a ballast tank to rebalance the ship, the police said. But instead of pure water, there was a mixture of water and fuel in the tank. Police suspect that between 1,000 and 5,000 liters of the mixture ended up in the river.
Drone footage from the fire department showed that an oil film about 400 meters long had formed on the Danube from the pier to the top of the town. Firefighters set up oil barriers on the river. Because of the low water level, the Danube flows more slowly than usual, so the fuel does not spread as quickly.
According to the police, the fuel from the ship flying the Swiss flag could still be clearly smelled further downstream in the city. According to the information, the smell may persist in the old town in the coming days.
Investigators were initially unable to estimate what impact the incident had on the environment. It also remained unclear why diesel was stored in the ballast tank. The police started the investigation.

A study in the journal Science shows that rising temperatures due to climate change are leading to a loss of species on European mountain peaks, while at the same time new species such as alpine bluegrass and arnica are conquering the peaks. The research analyzed data from 62 mountain peaks between 2001 and 2022.
After around 100 years of extinction, the wolf has been found again in Germany since the turn of the millennium, which has led to an emotional dispute about its protection. While environmentalists welcome its return, hunters and some district offices in Bavaria are calling for it to be made easier to shoot, citing the protection of farm animals. The Bundestag has cleared the way for easier shooting, with individual districts such as Oberallgäu and Ostallgäu having designated hunting areas. Critics such as the Association for Nature Conservation in Bavaria point out that individual wolves like GW999m have never killed livestock and that the hunt is therefore unfounded.

In Croatia, tens of thousands protested against an illegal landfill in Gospic that is said to contain toxic waste from Italy, Slovenia and Germany. The demonstrators are demanding the renovation of the landfills, a ban on importing waste and new waste management. Since February 2025, Europol has been investigating 13 suspects who are said to have made at least four million euros in profit.
Expeditions on Mount Everest contribute significantly to the melting of the Khumbu Glacier through fuel consumption and human waste. According to a study, around 2,500 tons of ice melt every year due to the heat generated in the base camp.

The Helmholtz Center GFZ warns of ongoing water shortages in Germany and Europe. Despite a rainy year in 2024, water storage has been steadily declining since 2015, mainly due to falling groundwater levels. Heat increases potential evaporation, while precipitation levels show no long-term negative trend. Data on the hot summer of 2024 will not be available until autumn.
After an extremely dry summer, forest experts warn of the risk of branches breaking in autumn and advise walkers to stay on paths and look up. Climate change is changing the tree species in German forests in the long term.
