Passage - 6 As oceans warm and absorb increasing amounts of carbon dioxide from the atmosphere, they undergo acidification. This change in ocean chemistry reduces the concentration of carbonate ions, which are essential building blocks for calcifying organisms like corals, molluscs, and some forms of plankton. The decline of these foundational species disrupts marine food webs, diminishes fish stocks, and weakens the natural coastal protection that coral reefs provide against storm surges.
