As atmospheric CO 2 continues to increase, more and more CO 2 enters the ocean, which reduces pH (pH is a measure of acidity, the lower the pH, the more acidic the liquid) in a process referred to as ocean acidification. Declines in surface ocean pH due to ocean acidification are already detectable and accelerating.

The Montreal Protocol on Substances that Deplete the Ozone Layer, signed in 1987, has been successful in that the amount of chlorofluorocarbons is now slowly diminishing. A common misunderstanding, however, is the belief that the ozone problem has been solved and the ozone layer is back to its original state.
