4PLANET IMPACT / ISSUE
Ocean acidification
Uptake of anthropogenic carbon dioxide changes seawater carbonate chemistry, affecting conditions for marine organisms.
Why it matters
Ocean acidification is driven directly by carbon dioxide uptake and carbonate chemistry, not by warming itself.
What the sources establish
IPCC AR6 documents ongoing ocean acidification caused by uptake of anthropogenic carbon dioxide and associated changes in ocean carbonate chemistry.

Published action
No project on this issue has passed the IMPACT publication gate yet. That is not evidence that no work exists.
Known and not established
- Local pH observations and global trends must be distinguished, and organism-level effects require appropriate evidence.
- This issue record is source-grounded context, not proof that any particular project, action or intervention is effective.
