Ocean Acidification ‐ A Paleo Perspective
Dissolution of atmospheric CO 2 in seawater has lowered ocean pH and carbonate ion concentrations with impacts on marine organisms and ecosystems. The geological record contains long‐term evidence for a variety of global environmental perturbations, including ocean acidification, and the biotic resp...

Dissolution of atmospheric CO 2 in seawater has lowered ocean pH and carbonate ion concentrations with impacts on marine organisms and ecosystems. The geological record contains long‐term evidence for a variety of global environmental perturbations, including ocean acidification, and the biotic responses associated with them, and can provide insight into consequences of current anthropogenic acidification. This e‐lecture focuses on the paleo‐perspective of ocean acidification, proxy evidence for pH changes and several events exhibiting evidence for elevated atmospheric CO 2 , global warming, and ocean acidification over the past ˜300 million years are reviewed. Comparison between these events and the present suggests that the current and projected rate of acidification may be unprecedented in past events with unknown consequences for marine life and humans who depend on it.
