A critical measure of the ocean’s health suggests that the world’s marine systems are in greater peril than scientists had previously realized and that parts of the ocean have already reached ...

The world’s oceans absorb about a quarter of humanity’s carbon dioxide emissions, buffering us against higher atmospheric CO2 levels and greater climate change. But that absorption has led to a ...

Sharks are some of the world’s most formidable predators, but their place at the top of the marine food chain may be threatened by ocean warming and acidification. As carbon dioxide levels in the ...

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 ...

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 ...
