Ocean Acidification Crosses Planetary Boundary, Threatens Global Marine Ecosystems
A recent study reveals that ocean acidification crossed a critical planetary boundary five years ago, posing an existential threat to marine ecosystems and human societies. d
What is Ocean Acidification?
- Ocean acidification occurs when oceans absorb excess carbon dioxide (CO₂) from the atmosphere, lowering pH levels and making seawater more acidic.
- This reduces calcium carbonate levels, which marine organisms like corals, mollusks, and sea butterflies need to build shells and skeletons.
- The boundary for safe ocean acidity is crossed when calcium carbonate availability drops below 20% of pre-industrial levels. The current global average is now at 17%.
