This is the drop in
seawater pH as the oceans
absorb an estimated 22 million tons of carbon dioxide
from the 80 million tons emitted each day by human activities.
just a small example: rain washes CO2
from the air into the sea - > water turns CO2 into carbonic acid - > coral
absorbs that compound — > keeps the carbon for itself - > releases the oxygen
from the CO2 molecule, to replenish the
seawater with oxygen.
Although the CO2 that is taken up by the ocean does not contribute to greenhouse warming, ocean warming reduces the solubility of carbon dioxide in
seawater; and thus reduces the amount of CO2 the oceans can
absorb from the atmosphere.
Fish are known to
absorb calcium
from seawater, binding it to carbon and excreting it as a carbonate molecule that can form a weak base capable of neutralizing ocean acidity.
It does this by shifting the series of equilibria (below) to the right, thereby increasing the capacity of
seawater to
absorb carbon dioxide
from the atmosphere and by decreasing the propensity for
seawater to desorb carbon dioxide into the atmosphere.»
