North Sea warming twice as fast as world's oceans

 Climate change has caused the North Sea's temperature to increase twice as fast as that of the world's oceans, according to Germany's Environment Ministry.

The average temperature of the North Sea rose by 1.67 degrees Celsius (3 degrees Fahrenheit) over the past 45 years, during which time the temperature of oceans such as the Pacific or Atlantic increased by 0.74 degrees Celsius on average.

That is according to an environment ministry response to a parliamentary question from the Green Party, the Neue Osnabrücker newspaper reported on Saturday.

The data is based on assessments up until 2010 from the Intergovernmental Panel on Climate Change and the Alfred Wegener Institutes.

The German government warned that the North Sea's temperature could rise by another 1.7 to 3.2 degrees Celsius by 2100.

The temperature increase could lead to the displacement of "indigenous species that fail to adapt," it warned.

"The warming of the sea waters has repercussions for many types of marine organisms. Especially, species that are sensitive to temperature will vanish," the Environment Ministry said.

As a result, cold-water species such as cod are likely to move further north after the degradation of their ecosystems and overfishing already hit populations.

In its place, fish accustomed to warmer waters such as the red gurnard, striped mullet, sardines, anchovies and sea bass are likely to move into the North Sea's once colder waters.

The impact of climate change on marine species also carries implications for fisheries.

The rising sea temperature is also expected to increase the intensity and frequency of storms along Germany's low-lying North Sea coast.

The North Sea last year recorded its second-highest average temperature of 11 degrees Celsius. Only in 2014 was the average temperature higher, at 11.4 degrees Celsius.
