“In 2025, the North Sea reached an average temperature of 11.6 degrees Celsius, the highest value recorded in the data series since 1969,” the BSH said in a statement.
Continue to rise for centuries
BSH chairman Helge Heegewaldt uses the publication of the data to once again warn about the consequences of climate change. “Even if we immediately stopped greenhouse gas emissions worldwide, sea levels would likely continue to rise for centuries.” That’s why it’s important to “do more to protect the climate,” he argues.
The seas around the world are warming as a result of climate change. According to the UN climate panel IPCC, the rate at which the oceans are warming has more than doubled since 1993.
