Global warming already has a significant impact in the North Sea.
It caused the displacement of benthic schools of fish northward or to deeper layers of the ocean. These variations concern twenty-one of the thirty-six species studied by a team of British researchers (1) that has accumulated data between 1977 and 2001.
Among the species observed were cod, hake and monkfish. If current trends continue, some species may withdraw completely from the North Sea by 2050, oceanographers argue. (1) Science, 12 May 2005
