This decline corresponds to a 30 % change in oceanic acidity. Observed reductions in surface-water pH are nearly identical across the global ocean and throughout Europe’s seas. Ocean acidification in recent decades is occurring a hundred times faster than during past natural events over the last 55 million years. Ocean acidification already reaches into the deep ocean, particularly in the high latitudes. Average surface-water pH is projected to decline further to 7.7 or 7.8 by the year 2100, depending on future CO 2 emissions. This decline represents a 100 to 150 % increase in acidity. Ocean acidification may affect many marine organisms within the next 20 years and could alter marine ecosystems and fisheries.

This change has occurred at a rate that is about a hundred times faster than any change in acidity experienced during the past 55 million of years. A further decline of 0.3-0.4 pH units, projected for surface waters during the 21st century, represents a 100-150 % increase in acidity.
