Does CO2 lower pH?

As mentioned,

when carbon dioxide is dissolved in water, the release of hydrogen ions in carbonic acid is what lowers the pH

. As CO

2

levels increase around Earth, the amount of dissolved CO

2

also increases, which increases the amount of carbonic acid, therefore decreasing the pH.
