description	Climate change is unambiguous and its effects are clearly detected in all functional units of the Earth System. This paper presents analyses of sea surface temperature and show that climate change is affecting both biological and ecological systems of the world and most specifically the North Atlantic and its adjacent seas. Changes are seen from phytoplankton to zooplankton to fish and are modifying the dominance of species and the structure, the diversity and the functioning of marine ecosystems.
