Research published Sunday in the scientific journal Nature Climate Change claims that warning sea levels in the Baltic Sea are strongly linked to recent blooms of the Vibrios bacteria group, which have corresponded with an uptick in humans reporting foodborne illnesses in northern Europe.

And while the study notes that the Baltic Sea is “the fastest warming marine ecosystem examined so far anywhere on Earth,” scientists also found that other temperate and even cooler regions, like Peru, Chile, Israel, the U.S. Pacific northwest and northwest Spain, have all seen growth in Vibrios infections after warmer weather.
