Increased atmospheric CO2 concentrations might have what effect on seawater?

Question

Quizplus · Accepted Answer

Increased atmospheric CO2 concentrations lead to an increase in dissolved CO2 in seawater, which creates more carbonic acid in the water. This then leads to a decrease in pH and an increase in acidity, causing a reduction in the concentration of carbonate ions in the water. As a result, marine organisms that rely on carbonate ions to build their skeletons or shells may have difficulty adapting to these changes.
