Informative article about the rise of ocean acidity in recent years, and its impact on the environment. This report cites recent findings from the University of Chicago and Columbia University, among others, which suggest that ocean acidification could decimate corals and a large number of other species. Thoughtful and well-documented article on an important issue.

Without giving opponents ground to complain of excessive predictions of disaster, Leahy presents a good introduction to the issues--and questions surrounding--acidification of the oceans. Findings from the most northwestern point of continental US warrant a certain amount of alarm.

The oceans cover nearly 71% of the surface of Earth, and play a critical role in our weather, water, food, and the overall habitability of our planet. Tatoosh, a tiny, remote island off the northwest tip of Washington state, is the point where Puget Sound and the Pacific Ocean meet. The entire Olympic Peninsula is among the least-inhabited, most protected chunks of coastline, home to wildlife, coastal estuaries, bird and marine sanctuaries. News that we're killing marine life in ... More »

Ocean acidification is a very new field of science and the best ways to do research are still being investigated. In fact, the Leibniz Institute of Marine Sciences was host ... More »

very factual, this story also includes the reservations and unknowns regarding the increase in ocean acidity and the loss of mussels and other shellfish in the study area. unfortunately the global/climate crisis has been less conspicuous lately with so much news of the financial crises that appear more pressing. there is a warning here that the oceans will be very different in 20 years, but not one about the future economic picture if attention is not paid here.

Good story but doesn't address the principle problem. It isn't limiting CO2, it's limiting population, but maybe that's too scarey for some people

An important warning about what could very well eventuate over the whole ocean

Buffers by their nature can absorb a quantity of acid without hardly any pH change. Once the buffer is used up, a tiny amount more acid will cause a sharp drop in pH. As far as I know, sea water is multiply buffered and so should acidify in a number of steps. The question is, how close are we to the first precipice and is the first step acidic enough to start the dissolution of Calcium carbonate. A marine chemist with a pH metre and a spare week should be able to work out the ... More »
