Climate change impact on marine ecosystems

Climate change impacts marine ecosystems primarily through ocean warming, acidification, and sea level rise. Warmer waters can disrupt species habitats, reduce fish populations, and cause coral reefs to bleach and die. Increased CO₂ absorption makes oceans more acidic, harming shell-forming creatures like mollusks and plankton. Rising sea levels alter coastal habitats and shoreline ecosystems. These changes threaten the balance of marine life, affecting biodiversity, fisheries, and communities that depend on the ocean. Overall, climate change weakens the health and resilience of marine ecosystems, jeopardizing their ability to support life both above and below the surface.
