Ocean Acidification and Climate Change

What do scientists believe is causing the waters around the Florida Keys and elsewhere to become more acidic? How does this affect the pH of the seawater?

What trends do you notice on the graphs above?

If these trends continue, what would you expect the CO2 and pH levels to be today?

Although this data is taken from Hawaii, we can assume oceans around the world are experiencing similar situations, as noted in the article. What other oceanic characteristics might have an impact on the rate of these changes?

How might a pH change have an effect on marine organisms? Give at least three examples.

The following equation can be used to explain ocean acidification. What is one key aspect that offers evidence of the ocean becoming more acidic?

Based on the information above, which substances are more acidic than sea water?
