New research says that the rate of warming in the Baltic Sea has coincided with the appearance of Vibrio infections in people living north of the continent.
British, Finish, Spanish and American scientists have contributed to the examination and their findings have been published in the journal Nature Climate Change.
The Vibrios are a group of bacteria which are known to grow in warm, tropical marine environments.
Some of the infections it can cause in humans include cholera and gastroenteritis. The symptoms are alike to those that occur from eating raw or undercooked shellfish or from exposure to seawater.
The findings discovered by the scientists show that the temperature of the waters rose by one degree while the cases of Vibrio rose by nearly 200%.
The journal article states: "[It] represents, to our knowledge, the fastest-warming marine ecosystem examined so far anywhere on Earth."
