Climate change and the ocean

Climate change has serious, long-term, and far-reaching negative consequences for our ocean.

Tale of two climate crises gives clues to the present

Figuring out what lies ahead for our species and our planet is one of the most pressing and challenging tasks for climate scientists. While models are very useful, there is nothing quite like Earth's history to reveal details ...

Stony corals: At the limits of adaption?

Corals fascinate amateurs and experts alike: small polyps that extract calcium carbonate from seawater and use it to build their elaborate skeletons. But climate change, with rising water temperatures and increasing ocean ...

Climate change could shrink oyster habitat in California

Ocean acidification is bad news for shellfish, making it harder for them to form their calcium-based shells. But several other factors related to climate change could also make California bays less hospitable to shelled organisms ...

Study considers sensory impacts of global climate change

Studies of how global change is impacting marine organisms have long focused on physiological effects—for example an oyster's decreased ability to build or maintain a strong shell in an ocean that is becoming more acidic ...

Ocean acidification

Ocean acidification is the name given to the ongoing decrease in the pH of the Earth's oceans, caused by their uptake of anthropogenic carbon dioxide from the atmosphere. Between 1751 and 1994 surface ocean pH is estimated to have decreased from approximately 8.179 to 8.104 (a change of -0.075).
