A map with the assessment shows increases in the populations of warm-water species around coasts of northern Europe, including the west coast of Scotland.
Warmer water is linked with an increase in harmful algal blooms which can kill fish by lowering the amount of dissolved oxygen in the water, and cause disease by damaging the fish’s gills.
An international group of marine scientists led by Professor Michael Burrows of the Scottish Association for Marine Science (SAMS) in Oban has compiled the comprehensive assessment of how ocean warming is affecting the species mix. It is published in the journal Nature Climate Change.
Researchers analysed three million records of thousands of species from 200 ecological communities from the North Atlantic, Western Europe, Newfoundland and the Labrador Sea, east coast USA, the Gulf of Mexico, and the North Pacific from California to Alaska. Read the article.
