Ocean-Based Geoengineering Approaches
Ocean-based geoengineering is key in fighting climate change. It uses the oceans to cut down carbon dioxide in the air. This slows global warming. Methods include iron fertilization, artificial upwelling, and enhanced weathering in the sea.
These methods help the ocean absorb more carbon dioxide. They also support biodiversity and lessen climate change's harm on marine environments. For example, iron fertilization adds iron to the sea to grow phytoplankton. These plants take in carbon dioxide as they grow.
Artificial upwelling and enhanced weathering are also being looked into. They use tech to bring deep water to the surface. This helps marine life grow and turns carbon dioxide into solid minerals. More study is needed to see if these methods work well and how they affect biodiversity and marine environments.
