Ocean Acidification

Ocean Acidification (OA) is a term used to describe changes to the chemistry of the ocean.

It occurs when carbon dioxide gas (or CO2) is absorbed by the ocean and reacts with seawater to produce acid. Although CO2 gas naturally moves between the atmosphere and the oceans, the increased amounts of CO2 gas emitted into the atmosphere, mainly as a result of human activities (e.g. burning fossil fuels), has been increasing the amount of CO2 absorbed by the ocean, which results in seawater that is more acidic.

Note: the water being more acidic does not mean its actually acid, rather it is less alkaline or base, seawater pH is typically limited to a range between 7.5 and 8.4 - with 7 being pH neutral.

    The NGO Partnership for Observation of the Global Oceans (POGO) is after $15B upfront, then $5B a year to improve our ability to measure ocean acidification on the basis of a 0.1 change in pH from 8.2 to 8.1. This is monumental waste of money and we explain why.
