When most people hear the phrase "ocean acidification," they think of coral reefs, shellfish or declining fisheries. Those ...

Since the Industrial Revolution, scientists estimate that the ocean has become around 30% more acidic from the uptake of additional anthropogenic carbon dioxide. Ocean acidification has widespread ...

Scientists have known for decades that soaring atmospheric carbon dioxide emissions are causing changes in ocean chemistry, threatening marine life and ecosystems. In June 2025, a study found that ...

An unhealthy sea butterfly, or pteropod, showing effects of ocean acidification including ragged, dissolving shell ridges on upper surface, a cloudy shell in lower right quadrant, and severe abrasions ...

Ocean acidification is the lowering of seawater pH over time, as the ocean absorbs carbon dioxide (CO 2) from the atmosphere. The pH scale is used to measure how acidic or basic a water-based solution ...

A new assessment finds that the world’s oceans crossed the safe threshold for acidification in 2020, breaching a key planetary boundary and posing serious threats to marine life. Ocean acidification ...

An international research team develops a rubric for governments and policymaking bodies to evaluate preparedness for ocean acidification. In a paper published today in the journal Environmental ...

Increasing global capacity for observation of and research in ocean acidification is key to help minimize the impact of climate change on oceans, participants heard at a side event at the global ...
