North Seafish are de­clin­ing due to ris­ing tem­per­a­tures

ARISE IN tem­per­a­ture of oceans and seas could se­ri­ously af­fect popular North Sea fish, such as had­dock, plaice and lemon sole, which thrive in cold wa­ter. A team of Bri­tish re­searchers have found that the North Sea, which washes the eastern shores of Bri­tain, has warmed four times faster than the global av­er­age in the last 40 years and would warm fur­ther over the com­ing cen­tury. But its fish species will not be able to move north­wards to avoid warm­ing since those ar­eas are not deep enough. As their pop­u­la­tion de­clines, warmer wa­ter fish from south­ern Europe are likely to take their place. The re­searchers' model used fish­eries data­bases and cli­mate model projects.
