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 ...

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 ...

A more acidic ocean could give some species a glow-up. As the pH of the ocean decreases as a result of climate change, some bioluminescent organisms might get brighter, while others see their lights ...

“The signs of the ocean in distress are all around us”, said Peter Thomson, Special Envoy of the Secretary-General of the United Nations for the Ocean, at the conference in Nice, France last week.

An international study published in Communications Biology has used unique coral reefs in Papua New Guinea to determine the likely impact of ocean acidification on coral reefs in the face of climate ...

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 ...
