Warming ocean temperatures have changed the distribution of many critical marine species off the British coast, as warm water fish are increasingly expanding into northern waters and cold-water species are swimming to colder depths, according to a new report. The report of the Marine Climate Change Impacts Partnership, published by the UK and Scottish governments, found that warm water species such as the bluefin tuna and thresher sharks are more frequently appearing in the waters off southwest England and squid have become increasingly abundant in the North Sea. One southern species, the bib, has moved north by 212 miles (342 kilometers) in the last two decades, while common North Sea species such as cod and lemon sole are swimming at an average of 5.5 meters deeper per decade. The report, based on an analysis of scientific studies, warns these changes pose potential threats for native species and the commercial fishing industry as changing water temperatures could introduce invasive species and new diseases.
