oceanic uptake of CO2

Oceanic uptake of CO₂ refers to the process where the world's oceans absorb carbon dioxide from the atmosphere. CO₂ dissolves into surface waters, driven by natural factors like wind and temperature differences. Once in the ocean, it can form carbonic acid, bicarbonate, and carbonate ions, which help buffer the ocean's pH. This process plays a key role in regulating global climate by reducing the amount of greenhouse gases in the atmosphere. However, increased CO₂ absorption can lead to ocean acidification, impacting marine life and ecosystems.
