Ocean acidification








Ocean acidification is the newest global environmental threat
confronting the earth.

It is the consequence of the same anthropogenic excess that is
responsible for global warming-release of much more CO2 at much faster
rates, minute after minute, than the earth's capability to assimilate.



Considering that oceans cover almost 70% of the earth's surface, any
upset in the balance of forces in the oceans due to anthropogenic CO2
emissions has, potentially, much more massive consequences than the
impacts scientists are witnessing on the rest 30% of the earth.

Ocean acidification is the name given to the lowering of ocean pH that
is beginning to occur because the oceans are being forced to absorb CO2
at a much faster rate during the last few decades than it has been over
the previous thousands of years.



The term does not imply that the oceans have actually become acidic, or
will become acidic in the near future; it signifies a shift of ocean pH
toward less alkaline levels.



This shift has already threatened coral reefs and calcifying organisms.
The latest forecast based on the most sophisticated models and the most
authentic field data indicate that the adverse impact may become
precipitous in the much more immediate future than was forecast
previously.



Ocean acidification has also come to be called the other CO2 problem.
Oceans are also absorbing large quantities of two more acid-forming
gases being released at unprecedented rates into atmosphere-SOx and
NOx. Thus far, on a global scale, their impact has been relatively
minor; less than 3% of the impact of CO2, but is expected to grow in
magnitude as the emissions continue to increase.
