Pteropods, or sea butterflies, are pelagic molluscs whose delicate aragonitic shells render them especially susceptible to declining carbonate saturation. As the ocean absorbs anthropogenic carbon ...

Our planet is sick, and its life-threatening symptoms are getting worse, a new report warns. Earth has been pushed past multiple physical and chemical boundaries crucial for keeping the world a ...

A small but growing group of scientists and researchers is exploring ocean-based carbon geoengineering, which involves adding chemicals to make oceans less acidic. These largely untested experimental ...

The beleaguered snow crab of the Bering Sea may have one strength that could help their population endure rapidly changing marine conditions: an apparent resilience to ocean acidification. Research by ...
