Marine scientists are concerned that the process of ocean acidification constitutes a threat to sea life and to the cultures that depend on the ocean for their food and livelihood.

Ocean acidification is the ongoing decrease in the pH of the Earth's ocean. Between 1950 and 2020, the average pH of the ocean surface fell from approximately 8.15 to 8.05. [2] .

Aug 16, 2025 · Ocean acidification is the long-term, global decrease in seawater pH caused primarily by the ocean’s uptake of carbon dioxide (CO₂) from the atmosphere. As CO₂ …

Dec 24, 2025 · Ocean acidification is reshaping marine biology as rising CO₂ lowers ocean pH, dissolves shells, disrupts food webs, and threatens fisheries worldwide.

Ocean acidification refers to a gradual increase in the acidity of ocean water, caused mainly by human-emitted carbon dioxide mixing with the water.

Apr 22, 2025 · Explanation of the sources of pollution that cause ocean and coastal acidification, as well as the basic science behind these phenomena.

Ocean acidification is the 'evil twin' of climate change. Discover how it works, how it affects animals and how studying pH in the past can teach us about the future of our oceans.

Sep 25, 2025 · Because of human-driven increased levels of carbon dioxide in the atmosphere, there is more CO 2 dissolving into the ocean. The ocean’s average pH is now around 8.1, …

Of the total carbon-dioxide generated by human activities, around 25% is absorbed by the ocean, which mitigates the effects of global warming. However, the excess CO 2 changes the …
