Top Marine Ecosystems Most Threatened by Climate Change

Mangrove forests are vital coastal ecosystems that serve as natural barriers against storm surges and erosion. However, their location at the land-sea interface makes them extremely vulnerable to sea-level rise, ocean acidification, and rising water temperatures, all direct threats from climate change.

Offshore epipelagic ecosystems, encompassing the ocean's surface zone, are particularly vulnerable to climate change disruptions due to their direct reliance on sunlight for photosynthesis and their crucial role in the oceanic food web. Rising water temperatures, acidification, and changes in ocean currents directly impact the species inhabiting this layer, from phytoplankton to large predators, threatening their survival and the ecosystem's stability.

Rocky Reefs are marine ecosystems particularly vulnerable to ocean temperature fluctuations and acidification, key factors of climate change. Their physical structure and dependence on specific species make them susceptible to degradation, impacting the biodiversity they harbor.

Seagrass meadows are threatened by increased water temperatures and reduced light availability due to sedimentation.
