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 ...

Ocean acidification is a consequence of increasing carbon dioxide (CO 2) emissions, a greenhouse gas driving climate change. The ocean absorbs around one third of all human induced CO 2, causing a ...

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 ...

The ocean is the lifeblood of our planet—producing over half of the world’s oxygen, regulating global temperatures, and supporting millions of species. Yet today, marine ecosystems are under severe ...
