- When scientists discovered that increasing the ocean’s natural alkalinity could enhance seawater’s capacity to absorb and store carbon dioxide (CO₂), the idea quickly gained attention as a potential geoengineering solution to climate change.
- Early visions suggested it could remove gigatonnes of CO₂ from the atmosphere each year. But the reality is far more complex.
- In a new article published in Nature Reviews Earth & Environment, scientists urge that the focus of ocean alkalinity enhancement (OAE) be shifted from a science fiction–flavored geoengineering intervention to a practical, flexible tool for local CO2 management.
