The ocean is both a victim and a hero in the fight against climate change. Its role in carbon recycling is vital to the Earth’s climate system, but this function has come under strain due to excessive anthropogenic CO₂ emissions. Ocean acidification, driven by this excess carbon, poses a serious threat to marine life, ecosystems, and human livelihoods. While several methods exist or are being developed to manage oceanic CO₂, each comes with its own set of challenges and uncertainties. The most prudent course of action involves a combination of emissions reductions, protection of natural marine systems, and cautious innovation in CO₂ removal technologies. By understanding and respecting the ocean’s central role in the carbon cycle, humanity can chart a path toward a more sustainable and resilient future.
