  By 2100 the overall level of the Mediterranean could rise between 3 and 61 cm (1.2 and 24.0 in) as a result of the effects of climate change. This could have adverse effects on populations across the Mediterranean:
  
  Coastal ecosystems also appear to be threatened by sea level rise, especially enclosed seas such as the Baltic, the Mediterranean and the Black Sea. These seas have only small and primarily east–west movement corridors, which may restrict northward displacement of organisms in these areas. Sea level rise for the next century (2100) could be between 30 and 100 cm (12 and 39 in) and temperature shifts of a mere 0.05–0.1 °C (0.09–0.18 °F) in the deep sea are sufficient to induce significant changes in species richness and functional diversity.
