This briefing summarises some of the ways in which climate change is impacting Europe’s marine ecosystems. It identifies how various ecosystem features are influenced by climate change and spotlights potential areas of concern. It also highlights areas where marine life may be more impacted by climate change compared with other areas. This work supports the recent integration of climate change as a key consideration in the Marine Strategy Framework Directive (MSFD). It does this by presenting a spatial description of the vulnerabilities of marine areas to climate change.
