Ocean acidification is often described as the evil twin of climate change. Prof Richard Twitchett explains what ocean acidification is and what it could mean for the planet. Earth's oceans are ...

A research team has shown that methanogens, micro-organisms ubiquitous in low-oxygen environments like aquifers, soil and even permafrost, can propel their growth by dissolving calcium carbonate ...

The ocean water in the Pacific Northwest is more vulnerable to rapid acidification, where the carbon dioxide levels are naturally higher.

Human-caused climate change exacerbates ocean acidification ... This lowers the pH of sea water, making it more corrosive to calcium carbonate and leading to stressful conditions for marine ...
