The study examined many parts of the marine ecosystem, including fish, algae, sea turtles, dolphins, and more. Seagrass meadows, like Posidonia oceanica, could vanish by 2100. Corals are more resistant but would still face high risk at 3°C of warming. Fish populations could decrease by 30-40% and move northward. Moreover, coastal areas are especially vulnerable to rising sea levels and erosion.
