Ocean Acidification
Increasing CO₂ absorption lowering ocean pH.
Direct Ocean Carbon Capture Explained
Direct ocean carbon capture (DOCC) is an emerging climate technology that removes CO₂ directly from seawater to enhance the ocean's natural carbon sink. While…
Ocean Alkalinity Enhancement: Potential and Risks
Quick verdict: Ocean alkalinity enhancement is a promising but unproven carbon removal method that could also mitigate ocean acidification. It faces significant uncertainties regarding…
How Carbon Dioxide Changes Ocean Chemistry
When carbon dioxide (CO₂) from the atmosphere dissolves in seawater, it triggers a series of chemical reactions that lower the ocean's pH, a process…
Ocean Acidification vs Ocean Warming: Key Differences and Combined Impacts
Ocean acidification and ocean warming are two distinct but interconnected consequences of rising atmospheric carbon dioxide. Acidification refers to the chemical change in seawater…
Ocean Acidification: Causes, Evidence and Ecological Consequences
Learn what ocean acidification is, how rising CO₂ changes seawater chemistry, its impacts on marine life, and why it has become a planetary boundary.
