These studies suggest ocean acidification negatively impacts coral reefs and marine life by reducing coral recruitment, survival of reef fishes and shelled molluscs, habitat complexity, and invertebrate recruitment, while some studies suggest coral reefs can locally buffer these impacts.

Ocean acidification (OA) refers to the decrease in pH of the ocean's surface waters due to the uptake of atmospheric carbon dioxide (CO2). This phenomenon poses a significant threat to marine ecosystems, particularly coral reefs and various marine life forms. The following synthesis presents key insights from multiple research papers on the impact of ocean acidification on coral reefs and marine life.
Impact on Coral Recruitment and Growth:
Effects on Marine Calcifiers:
Changes in Marine Invertebrate Communities:
Behavioral Effects on Marine Life:
Ecosystem-Level Impacts:
Ocean acidification poses a multifaceted threat to coral reefs and marine life, particularly affecting coral recruitment, growth, and the structural complexity of reef habitats. Marine calcifiers, including corals and mollusks, are especially vulnerable, with long-term studies indicating limited capacity for acclimatization. While some marine invertebrate communities may adapt, others face significant declines. Interestingly, recent research suggests that the behavior of coral reef fishes may not be as impacted as previously thought. Overall, the cascading effects of ocean acidification on marine ecosystems underscore the urgent need for mitigating CO2 emissions to protect these vital habitats.
