NSF Ocean Sciences Division Director David Conover answers questions about ocean acidification

The video explains how increasing CO2 levels in the atmosphere lead to ocean acidification, affecting marine life by lowering pH levels. It highlights historical contexts of ocean acidity and the uncertainties of future impacts due to unprecedented CO2 levels. The video also discusses the challenges faced by marine species, particularly those with calcareous skeletons, in building shells in more acidic conditions. Finally, it emphasizes ongoing global research efforts to understand the broader impacts on ocean systems.
