Oceans turning to acid from rise in CO2

Editor : A 0.1 change over 200 years? I'd like to see how they calculated that, and their standard error - but as with the last article, don't panic just yet! Still, if it's a real trend, it could be alarming. Oceans are quite big... It takes a lot of acid to change its pH, I guess!

A report issued by the Royal Society in the U.K. sounds the alarm about the world's oceans. "If CO2 from human activities continues to rise, the oceans will become so acidic by 2100 it could threaten marine life in ways we can't anticipate," commented Dr. Ken Caldeira, co-author of the report and a newly appointed staff scientist at the Carnegie Institution's Department of Global Ecology in Stanford, California.* The report on ocean acidification was released today by the Royal Society.

Many scientists view the world's oceans as an important sink for capturing the human-induced greenhouse gas CO2 and slowing global warming. Marine plants soak up CO2 as they breathe it in and convert it to food during photosynthesis. Organisms also use it to make their skeletons and shells, which eventually form sediments. With the explosion of fossil-fuel burning over the past 200 years, it has been estimated that more than a third of the human-originated greenhouse gas has been absorbed by the oceans. While marine organisms need CO2 to survive, work by Caldeira and colleagues shows that too much CO2 in the ocean could lead to ecological disruption and extinctions in the marine environment.

When CO2 gas dissolves into the ocean it produces carbonic acid, which is corrosive to shells of marine organisms and can interfere with the oxygen supply. If current trends continue, the scientists believe the acidic water could interrupt the process of shell and coral formation and adversely affect other organisms dependent upon corals and shellfish. The acidity could also negatively impact other calcifying organisms, such as phytoplankton and zooplankto
