(via Reactions) The ocean is getting more and more acidic. Can we solve it by emptying a giant bottle of antacid into the ocean? No… but the idea of lowering the ocean’s acidity in order to decrease ...

MAYOTTE, INDIAN OCEAN - NOVEMBER 2017: Diver from the Mayotte Marine Natural Park carry out a survey on the reef, called REEFCHECK, on November 27, 2017, Mayotte, Comoros archipelago, Indian Ocean.

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 ...

A research team led by Prof. Li Mingsong at Peking University has provided new insights into the Paleocene-Eocene Thermal Maximum (PETM) and its effects on ocean chemistry. The Paleocene-Eocene ...

Ocean acidification is sinking into marine regions as deep as 1500 metres, posing new threats to organisms like sea butterflies, sea snails and cold-water corals. The ocean is the largest natural sink ...

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 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 ...

Sharks are the most feared predators in the sea, and their survival hinges on fearsome teeth that regrow throughout their lives. But changes in the ocean's chemistry could put those weapons at risk.

Acidification is threatening the ocean’s ability to pull carbon dioxide out of our atmosphere, so scientists and startups are looking to ocean-sized antacids to raise its pH. While they might not be ...
