In "Study: Man-made ocean acidity threatens sea life," (1/23/12) Wendy Koch at USA Today explains recent findings published in the journal Nature Climate Change (on a topic that receives little media coverage), "Detecting regional anthropogenic trends in ocean acidification against natural variability" (1/22/12).USA Today excerpt: "Scientists have found that human-caused carbon dioxide emissions, from the burning of fossil fuels in the last 100 to 200 years, have already raised ocean acidity far beyond the range of natural variations. [T]hey say these emissions, which increase water acidity by reacting with saltwater, may significantly reduce the calcification rate of marine organisms such as corals and mollusks."
