Rising acidity threatens oceans

From ananova.com/BBC

Yet another stunning peace of evidence for the relentless destruction of our enviroment from our technological marvels.

What sort of a dump are we leaving our children ??

It should be possible to arrive at an educated estimate of the extent of the effects of humans and the long range implications. Stating a credible volume of surface water (oceans and seas mainly) and the existing average pH's overall, and applying the added chemical influence by human industrialization since a given year to arrive at a new pH value. (Note that this has similarities to a method used by early geologists to estimate the age of the earth by comparing freshwater and ocean salinity levels. ) Make sure one omits the estimated 50,000 tons or more of accumulating meteorotic space dust ,of various chemical composition, per year on average ... perhaps there is a more accurate value. Right now with the pressure/temperature/pH/salinity ratios in the vicinity of the Titanic wreck the skeletons (calcium) of the unfortunate dissolved long ago, unlike the skeletons contained within shipwrecks of much older dates in shallower water of freshwater seas. Overall the ocean is in much better shape than some localized areas of high salinity or other measureable chemical discrepancy. The most immediate effect of "Rising acidity threatens oceans" would probably be a reduction in the efficacy of coral reefs to maintain or increase their territory. Perhaps in the past few billion years Earth's geologic conditions favored or disfavored coral reef growth with (un)predicatable (ir)regularity, but you're right we don't have any excuse today to pollute the fragile ecosystems around the globe
