These changes pose significant threats to marine ecosystems, coastal communities, and global food security. Key findings include evidence of ocean acidification triggering past extinctions, neurological impacts on marine invertebrates, and ongoing alterations to seawater chemistry affecting calcifying organisms.\n\n*   **Ocean Acidification Linked to Past Extinctions:** Northwestern University scientists have identified chemical evidence within 113-million-year-old microscopic fossils suggesting ocean acidification played a role in one of the ocean’s most severe extinction events during the Cretaceous period.

This effect is attributed to rising levels of oceanic CO₂ impacting squid neurology.
