A northward shift of 1000 km of warmer-water plankton, with a similar retreat of colder water plankton, has been observed in the north-east Atlantic over the past 40 years as the seas around the UK have become warmer.

There is a correlation between plankton shifts and changes in various fish stocks.

Continued increase in sea temperature and ocean acidification may exert a major influence on plankton variability, with implications for primary production and climate control.
