From ABC Environment: OCEAN ACIDIFICATION has risen by a quarter since pre-industrial times as a result of rising carbon emissions, casting a shadow over the seas as a future source of food, scientists warned on Wednesday. In the past two centuries, the seas acidity level has risen 26 per cent, mirroring the proportion of carbon dioxide it absorbs from the air, they said in a report to the UN Convention on Biological Diversity meeting in South Korea. Rising acidity will have damaging consequences for shellfish, corals and other calcium-making organisms which play a vital part in the food web, they said. It is now nearly inevitable that within 50 to 100 years, continued anthropogenic [man-made] carbon dioxide emissions will further increase ocean acidity to levels that will have widespread impacts... on marine organisms and ecosystems and the goods and services they provide, they said.
